Vacuum press: features of varieties of vacuum presses, characteristics of a vacuum thermo and membrane press, as well as the operation of vacuum machines. Vacuum Presses Vacuum Press Machine

Furniture production in our country is very well developed. There are many companies that make cabinets, tables, headsets, etc. Consequently, competition in this market segment is unusually high. In order to make a good profit, enterprises of this specialization need to pay maximum attention to both the quality of their products and their appearance. Simply put, the furniture should be not only solid, but also beautiful. In order to achieve this, of course, it is necessary, first of all, to use high-quality machines in production.

Machine tools for the manufacture of blanks

In specialized enterprises, such as:

format machines. This equipment is designed specifically for cutting MDF or chipboard.

Milling and copying machines. They are necessary for applying a certain relief to the plates.

Presses for the production of bent facades.

They are necessary for processing facade parts when applying paint or varnish to them.

Also in the furniture industry, a vacuum-membrane press is mandatory, which will be discussed in this article. This equipment is used for pasting the facades of cabinets and sets with decorative PVC film or veneer. Modern machines of this type have a fairly simple design and are also easy to use.

The main elements of the design of the vacuum machine

The arrangement of this type of equipment is not too complicated. Any such machine consists of five main elements:

• A table on which furniture blanks are laid out. Its surface is usually sheathed with a metal sheet or thick tin.
• vacuum pump.
• clamping frame. This press element is also made of durable metal.
• heating installation. Different presses use different types of this equipment. The heating installation can be infrared or contact.
• Actually the press itself. It can be made in the form of a hinged or rolled cover.

Additional design elements

Such equipment is called vacuum because the dense pressing of the film to the blanks in it is carried out by completely pumping out air from under it. From the end of the table in such equipment there are shafts (one or more) for rolls of PVC film. In order for the workpieces to fit the material as tightly as possible, they are placed on special substrates on the table. When finishing MDF or chipboard with veneer, special glue is additionally used. The press is controlled using an automatic remote control. In this case, the operator has the ability to manually configure the equipment.

Types of presses

At the moment, enterprises use only two main types of such machines:

Actually vacuum presses. Used for finishing furniture blanks in a gentle way. Such installations can provide a pressure of no more than 0.95 kg/cm 2 .

Vacuum with additional pressure. Such equipment is much more expensive. At the same time, it can provide pressure up to 8.5 kg/cm 2 .

The first variety is usually used for gluing PVC film or for veneering simple blanks. Vacuum presses of the second type are used for facing MDF furniture parts with a complex configuration.

Membrane for presses

Both types of vacuum machines are usually supplemented with a special membrane. It is used most often when pasting blanks with veneer as an additional “press” that prevents unwanted movements during work. Also, the membrane is used when finishing parts with very thin films that do not tolerate extreme temperatures. This element is attached to hooks located along the perimeter of the clamping frame.

In such a sphere of the national economy as furniture production, only two main types of membranes are used. Most often, these elements are made of rubber. Sometimes durable silicone is also used. The latter is obtained by vulcanization, and therefore, it has all the qualities of natural rubber. At the same time, silicone also has a greater degree of wear resistance.

Among other things, the use of a rubber or silicone membrane in the press allows you to:

to veneer details of very small sizes;

reduce film waste.

Film finish

The procedure for gluing furniture blanks with PVC material using equipment such as a vacuum membrane press includes the following steps:

On the surface of the table, the substrates are carefully laid out. At the same time, technological gaps of several centimeters are left between them. This is necessary because during the pressing process, the film is stretched and compresses, including the ends of the blanks along the perimeter. Without gaps, this becomes simply impossible.

Blanks are laid on the substrates: cabinet doors, drawer slats, parts of the facade, etc.

The table with blanks is completely covered with a PVC film rolled off the rollers.

A clamping frame is lowered onto the film along the perimeter, pulling and straightening it.

Depending on the design, the press itself is lowered from above or advanced from the side.

The operator sets the temperature and pressure values ​​required by the technology on the control panel and turns on the equipment. After that, the film begins to warm up. As soon as its surface reaches a certain temperature, the vacuum unit is turned on. Air begins to be pumped out from under the film (at a given pressure and a certain speed).

After the set time has elapsed, the operator turns off the press and folds it back (or moves it back).

Vacuum presses are used most often in furniture industries, as well as other types of enterprises that produce products consisting of wood-based panels. Sometimes such devices are also used to give relief to materials, as well as to form products.

How the equipment works

The vacuum press for facades has the following components:

• a frame that is load-bearing and has a collapsible type
• desktop, which is also a carrier. A special clamping frame is installed on the table
• vacuum pneumatic working system. Without it, it is impossible to implement the entire technological process.
• retractable carriage. It is equipped with electric type heating devices. The vacuum press works with the help of automatic control, therefore, the performance of work on this equipment does not require the involvement of manual labor. A few operators involved in the maintenance and start-up of the plant are quite sufficient.

Kinds

Today there are several modifications of vacuum presses. They differ in automation and the number of additional options present on a particular device.

The press can be:

• auto. In such a press, all work is performed without the participation of an operator in
• semi-automatic. In such devices, opening the installation door, pressing the buttons to start it up, then turning off and removing the workpiece is carried out by the operator himself. The operator must also monitor the process of the installation
• membrane. In such a press, the surface is pasted over with a film or veneer. To do this, a material is placed in a heat-resistant membrane, on which glue is preliminarily applied. Then the membrane warms up, and the vacuum pump pumps air out of the membrane. As a result, negative pressure is formed in it. Under such conditions, the film or veneer is firmly adhered to the material.
• membraneless. Such a press is used for gluing thicker coatings. For thin films, this option is not suitable.

Today, the membrane-vacuum press is used more and more often, in comparison with the equipment of the old model. Such popularity is due to the fact that much less time is spent on processing the material using a vacuum press, but the quality of the finished product does not decrease, but rather increases.

Also presses can be: Types of vacuum pressing equipment:

• vacuum sublimation press
• 3d vacuum sublimation press
• press vacuum drying chamber.

Vacuum presses are characterized by a high level of productivity. The equipment has a rather high cost due to the fact that workpieces of large dimensions are processed on it.

3d vacuum sublimation presses are versatile electro-mechanical devices. They are needed in order to create souvenir products. They apply images to objects of regular and irregular shapes. Such equipment is most in demand when applying different images to ceramic, fabric, and other products. Modern production uses such presses to decorate decorative stones, patterns on the protective covers of cell phones, on crystals, puzzles.

In a vacuum sublimation press, an image is transferred from one medium to another. For this purpose, high pressure and elevated temperatures are used. The operation requires preliminary preparation of the pattern on a special surface and its fixing. After that, the temperature rises, and the air is pumped out. The products are of fairly high quality.

The marketable appearance of a product created using a vacuum press is distinguished by a longer period of operation. Another advantage of such devices is the fact that the resulting surface does not need further refinement. You can immediately assemble products.

Vacuum press operation

The vacuum press for MDF has a fairly simple principle of operation. First, the workpiece with glue applied to it is placed on the surface of the table. Next, a membrane for a vacuum press is placed on it. And in the closed position, the operation of the vacuum pump and the heating system begins. There is a simultaneous heating of the object to the required temperature and the creation of a vacuum.

Silicone membrane for vacuum presses is used when it is necessary to guarantee a tight fit of the film. The pump for the vacuum process is able to form a vacuum of different depths, it all depends on the properties of the material. In addition, it is necessary that the membrane is suitable for a vacuum press. It is worth purchasing along with the unit.

Types of membranes

Vacuum press membranes can be:

• silicone
• rubber.

Silicone membranes have a long service life. They can also be used in bag sealing machines for cold and hot pressing.

Rolled silicone membrane sheet is used as a membrane sheet in hot and cold membrane-vacuum and membrane presses for applying veneer to furniture facades, door panels and other shaped panels, creating bent-glued furniture products.

The membrane is made of an elastic silicone film or heat-resistant rubber. The rubber membrane has the ability to stretch up to 700%. The membrane is needed in presses, both for finishing with natural veneer, and when working with workpieces that have a complex profile (for example, if the film needs to be brought to the back of the facade) or high-gloss films. The last films must never touch the upper heating plate of the press. The membrane is also used when the dimensions of the film are smaller than the dimensions of the loading table or when the film thickness exceeds the standard 0.3-0.6 mm.

In most presses, the membrane is installed on a special frame with a hermetic seal along the upper and lower perimeters. Such a frame can be easily dismantled, thereby making a single-chamber press from a two-chamber press, and a two-chamber press from a three-chamber press. Thus, the operator can not only control the lining process more precisely, but also change the pressing mode, which is more suitable for the company's technology.

The tasks that the membrane performs:

• more evenly heats the film, in comparison with just hot air
• acts as a frame
• prevents film breaks
• does not allow air to enter under the membrane, which significantly reduces the amount of defects in production
• evenly transfers heat to end surfaces of a product.

The film shrinking procedure consists of the following steps:

• laying the workpiece on the table
• sealing
• film heating
• air extraction
• cooling
• cutting blanks and removing excess film from the facade.

The operator can press the membrane against the heating film before it touches the workpiece. As a result, the formation of air bubbles between the membrane and the film is excluded. After pressing, the pressure in the upper and middle chambers stabilizes.

At the same time, the air that enters the middle chamber separates the film from the membrane, and the finishing process becomes more like a membraneless method. The only difference is that the film is evenly heated. At the end of the press cycle, cool air enters the lower pressurized chamber to cool the workpiece slightly. This helps to prevent the film from peeling off the part during removal from the press, while the part is still warm.

The membrane is a consumable. If you follow all the rules of operation correctly, then it will last approximately 3000 working cycles. The average period of its operation is no more than two months.

Before you start creating a vacuum press with your own hands, remember that 5 years after assembly, the device needs to be upgraded or made new. If you correctly plan the purchase of components and do all the work correctly, then the cost of the press will turn out to be significantly lower than the factory device.

The first step is to create a good frame, since it is the support of the entire device. However, before that, select the optimal type of heating unit, because this will affect not only the design of the frame, but also all other components of the press. A retractable thermal module is best suited for this. It is easy to assemble, convenient to use, but it has quite impressive parameters.

To create a bed you will need:

• profiled steel pipe
• rails for thermomodule.

If you are good with a computer, then the design of the bed is best modeled using special 3D modeling programs.

Tools that may be needed for the job:

• small single-handed angle grinder with a disc diameter of 115 or 125 mm welding device
• electric drill
• locksmith set
• including hammer
• spanners
• pencil
• roulette.

When everything is assembled, you can get to work. First you need to cut the steel profile into parts strictly according to the cutting map. Lay them on a flat surface according to the project, align and fix with clamps. Next, start welding the parts. Welding seams must be cleaned with a grinder with a grinding wheel. After that, you can drill all the necessary holes, prime the part and paint it.

The table assembly procedure is perhaps the most important event. During design, you will determine its dimensions and material. Be sure to consider a method of fixing and sealing the connector elements in order to maintain an internal vacuum. The vacuum table is a design that consists of:

• baths
• pressure frame
• clamps.

The dimensions of the vacuum bath affect the number of workpieces placed in it. Experts advise making a bath about 2.5 meters long. The width should be chosen depending on the width of the PVC film used. Most often, the width is 1.4 m. And the height of the bath is provided taking into account the small space between the upper part of the facade and the film with which it will be covered. The bottom of the bath can be a steel sheet, the thickness of which is 2 mm, and the frame can be made from a profile pipe.

It is also possible to create a clamping frame and clamps from a profile pipe, its dimensions must completely match the dimensions of the bath. To keep the pressure frame up, 4 gas lifts must be installed and ensure that they can hold it. Clamps guarantee a secure and tight hold of the film during pressing. The upper frame must be firmly and evenly pressed against the perimeter of the tub. In fact, the clamps are eccentrics. They can be created from steel rolled metal. They need to be mounted in 8 pre-drilled holes in the vacuum table.

In the event that the table does not have a perfectly flat surface, it can be leveled with special epoxy compounds.

The vacuum system is responsible for removing and pumping out air so that the film easily fits the surface of the workpieces. When installing the system, pay attention to the following points:

• Purchase all components in retail so that they can be easily replaced
• it must guarantee the speed of pumping air and the depth of vacuum so that they are enough to create typical flat facades and overlays
• the air removal system should not harm the environment
• controlling and managing bodies should be simple and give signals about the current pressure, smoothly regulate the speed of air pumping out.

The thermal module is a heating device that allows you to evenly heat the film to the desired temperature and hold it for a certain time. The frame for it is made of a steel pipe with a cross section of 20 by 20 mm. To the frame, it is necessary to weld the cases of profiled wheel supports and L-shaped handles for movement along the rails of the module. Ball bearings can be used as wheels. After that, the frame must be sheathed with sheet steel and reinforced with aluminum blind rivets. On the side part in the casing, it is necessary to make rectangular openings for viewing windows and mount silicate glasses, darkening them in advance with a tinting film.

To improve the reflectivity, inside the thermal module must be equipped with aluminum foil. The next step is to install the heating elements. Linear lamps KGT (quartz halogen thermal) are excellent for this purpose. They need to be connected according to the electrical circuit. This scheme must take into account the requirements in terms of three-phase load symmetry and the possibility of zonal control of groups of lamps.

As you can see, the procedure for self-manufacturing a vacuum press is not so complicated. Remember that it is very important to use personal protective equipment, because working with such a device can become dangerous if safety rules are not followed.

The main equipment for the production of MDF facades in PVC film is a thermal vacuum press.Today, a huge number of presses with a wide variety of technical characteristics are presented on the Russian market.Therefore, before purchasing, you should ask yourself a few questions in order to correctly answer the main one - how to choose a vacuum press for MDF facades.

The size of the working surface of the vacuum press for MDF facades

When choosing the size of the working table of the press, the expected volume of production and the range of MDF products should be taken into account. Manufacturers of thermal vacuum presses for the manufacture of MDF facades offer equipment with a working surface of 1150× 1090 mm, such as, for example, a membrane-vacuum press for bent MDF facades from the New Technologies company, Penza. The maximum size of the working table of a vacuum press for MDF facade cladding is currently boasted by Latvian equipment VP -4000, from ISTRA-A (Latvia), with table 4000× 1400 mm.

Please note that the standard width of PVC film rolls for vacuum pressing is 1400 mm. Some European companies offer films with a width of 1420 and 1450 mm. However, the main manufacturers of equipment for membrane vacuum pressing are oriented towards the 1400 mm standard.

In addition, for continuous flow production of MDF facades, some developers offer membrane-vacuum presses with 2-3 working tables, such as Master PRO, Moscow. The movable heating carriage, moving freely over the working surfaces, provides alternate heating of the PVC film. The structure of the vacuum press can include a table for cladding curved facades.

The design of a vacuum press for MDF facades and its dimensions

With a shortage of working space in the furniture workshop, the size of the vacuum press for the production of MDF facades and the area it occupies will become a natural question. But we should not forget about the convenience of equipment maintenance. Here you should understand the design solutions for the location of the working table and the heating module offered by manufacturers of vacuum presses.

The main manufacturers offer the following options for the design of the membrane vacuum press:

· With movable heating carriage on rail guides. This design of the vacuum press allows you to lay out MDF facades from 3 sides.

· Vacuum press for MDF facades with hinged lifting thermal module. The effectiveness of this design lies in saving the working space of the furniture workshop. However, laying down parts and stretching the PVC film becomes more difficult.

· With pull-out table for loading MDF and PVC foil parts, such as the vacuum press for MDF facade cladding MTA-2500. Ideal for small furniture production, as it will compactly fit into any corner of the workshop.

· The most effective in terms of workshop space saving and serviceability are membrane-vacuum machines with vertical pneumatic or hydraulic lifting of the heating module, such as the VPF-2 vacuum press from a Latvian manufacturer, or the Italian PM ORMA press, which, among other things, allows to produce facing products with 2 -x sides.

Features of the configuration of membrane-vacuum presses for the manufacture of MDF facades

1. Heating module of the membrane vacuum press . At the current level of development, manufacturers of vacuum presses for cladding MDF facades in PVC film use quartz-halogen thermal heaters that provide fast heating with minimal energy consumption. In other embodiments, infrared lamps may be used. Some manufacturers of membrane-vacuum presses use hot air for heating, supplied through heating elements, to prevent uneven heating on the membrane surface. In addition, additional thermal equipment for heating the table can be installed on the vacuum press. Chinese machine tool manufacturers heat PVC film by pumping hot air underneath it.

2. Automation of the process of facing MDF facades in PVC film . Vacuum presses equipped with automation systems have proven themselves well in in-line and continuous furniture production. Human participation is reduced only to laying the details of the MDF facades on the desktop and then trimming the excess PVC film. However, in small businesses that work daily with a wide range of PVC films, it is easier to carry out the cladding process manually, “by eye”.

3. Silicone, rubber or rubber membrane . Most manufacturers supply a vacuum press for MDF facades with silicone membrane, which has high heat resistance and elasticity. With the help of a silicone membrane, some technological operations are performed for gluing various materials, giving them a curved shape according to a pattern, as well as for the rational use of PVC film with small bookmark volumes. In some designs of vacuum presses, the silicone membrane is mounted on a special frame, which makes it more convenient to use. In other cases, the process of cladding MDF facades in PVC film is based directly on the use of a silicone membrane, and it is an integral part of the equipment.

4. Vacuum pump. As a rule, modern membrane-vacuum presses for MDF facades are installed oil pumps, which currently have the highest performance. With a small size of the vacuum press table and a short pressing time, oil-free "dry" pumps with lower performance. As a budget option, a membrane-vacuum press can be installed VVN water ring pump. With a significant size of the working table of the vacuum press, the vacuum pump can be supplemented with a receiver. Some machine tool builders combine a vacuum supply with a counter-supply of high pressure, so a compressor may be required with the equipment.

5. Dividing frame . It is used when dividing the working table of a membrane-vacuum press for the simultaneous use of two types of film or one, in combination with a silicone membrane, for the rational use of PVC film with a small number of products.

6. Additional desktop . In large-scale production of MDF furniture facades in PVC film, the installation of one additional working table allows increasing the productivity of the membrane-vacuum press and, accordingly, the output by 1.5 times or more.

7. Membrane vacuum press control panel . When crimping MDF facades "in manual" mode, as a rule, two buttons are used to turn on the heating and the vacuum pump, as well as a valve that regulates the vacuum supply rate. More powerful and automated equipment requires an appropriate control panel.

8. Possibility of manufacturing radius (curved) MDF facades . In view of the design features, some membrane-vacuum presses do not allow the production of MDF radius facades and their cladding in PVC film. On the other hand, as for example the Master PRO company in Moscow, machine tool builders took care of this option by supplementing their equipment with additional devices.

9. Unwinders . Including with manual or pneumatic cutting of PVC film. Such equipment can significantly increase the productivity of a vacuum press with large production volumes.

10. Antistatic brushes . Allows to remove a static charge from a PVC film to facilitate its cleaning and eliminate debris sticking to its surface before feeding it to a vacuum press. They are installed in order to improve the quality of the manufacture of MDF facades and other products.

11. Support system. Special supports, including magnetic ones, are used as a substrate when laying MDF facades on the working table of a vacuum press. Some manufacturers even took care of such a “little thing”.

12. PVC Film Waste Briquetting Press, Silicone Membrane Tears and Damage Repair Devices, PVC Film Roll Storage Movable Racks - all this may not be included with a membrane-vacuum press for MDF facades, however, it is often offered by the manufacturer as additional equipment, such as, for example, German designers of vacuum presses BR 2600, Wemhoener. Such devices make the production of MDF facades more convenient and efficient.

Before you finally decide and choose a vacuum press for MDF facades, you should also study the price range, the availability of options for installation and adjustment of equipment, staff training, further warranty and service.

This machine is mainly used as a woodworking equipment. The principle of its operation is to cover wooden surfaces with a PVC film or veneer. The main consumer of this device are furniture factories. This is due to the fact that the process of lamination using a vacuum press significantly accelerates the productivity of the factory and makes it possible to create an exclusive design of furniture surfaces. In addition, the machine can be used to decorate bent interior items. This feature has become available due to the improvement of the press and the expansion of its capabilities. The same possibilities allow the use of carbon films and fiberglass to cover the surfaces of water and land transport. Such presses are called specific.

The coating of the surface with the processing material is very high quality and such a surface lasts for a long time. And the technology itself is very simple and consists in the simultaneous interaction of vacuum technology and heating of the working surface. The cost of the machine does not allow many factories to introduce it into their workshop, but if you still purchase it, then the payback will not be long in coming. The reason for this is the savings on the purchase of ready-made materials for cabinet furniture (for example), since by purchasing bare chipboard and processing it yourself on a vacuum press, it will be much cheaper than buying an already laminated pressed board.

Vacuum presses are:

• Book pressing. The top cover of the unit opens and closes in the form of a book. There are covers with manual and automatic drive;
• Conveyor pressing. A table equipped with a conveyor belt that feeds the processed material to the working body of the press. Such models have a design with one and two work tables;

Vacuum press vp 3000

A vacuum press is used to transfer an image or inscription to any surface of a product using sublimation. Sublimation is the process of printing under high temperature any image that has been previously printed on special paper to display it on the surface of the processed object. The final image can have both a black and white look and a color palette, including ultraviolet paints, which multifacetedly expands the possibilities of using a vacuum heat press. Due to the ability to transfer an image from paper to an object, such a unit is called a 3D press.

For the rational use of equipment, there are several features that save time and money in the event of a marriage. It's about temperature control. Depending on the material from which the object for processing is made, the temperature of the working membrane of the heat press must be different. If the applied image is underheated, then the image will turn out to be pale and vulnerable to mechanical stress. If you overheat, the picture will become blurry and the color contrast will change, wear resistance will also leave much to be desired.

What are vacuum heat presses?

• Household. Compact body designed to handle small items at low throughput rates. Although, modern models are quite multifunctional and are equipped with processors that control the temperature regime, which speeds up the crimping process;

Household heat press

• Industrial. They have a large working area and are able to apply 3D patterns at high speed;

This type of press differs from the usual vacuum press in that it is intended mainly for covering wooden and other surfaces with veneer. The membrane is an additional equipment that promotes a tighter fit of the material applied to the surface to be treated, thereby creating a lot of pressure in combination with an increased temperature, which makes it possible to fit the workpieces with such a hard material as veneer. In addition, membrane presses are widely used for applying film and similar raw materials to the relief surfaces of doors, columns, cornices, interior elements, structural facade slabs, and more.

Membrane vacuum press

Special equipment that is designed to create plastic molds, packaging, figures and other elements. For a certain product, an appropriate machine is needed, since everything depends on the dimensions, density of the plastic and the variant of the process.

The principle of operation of vacuum machines is the same in almost all modifications. A blank is placed inside the vacuum chamber (it is made of wood, gypsum, polystyrene foam, rubber, metal, etc.). Also, a raw material (plastic) is placed in the chamber, which becomes elastic under the influence of temperature and, when stretched, can increase its area up to 10 times. A pump is connected to the working chamber, which at the right time creates a vacuum, which ensures that the plastic adheres to the workpiece, completely repeating its shape. The thicker the plastic must be for the finished product, the more powerful the pump is required to create a vacuum.

Vacuum forming machine

Vacuum technology for food products, medicines, precious metals and banknotes. With the help of vacuum packaging machines, the process of decomposition of food molecules is inhibited and they are kept fresh for more than 20 days. By the same principle, tablets and banknotes are packaged to avoid moisture and dirt.

Vacuum packaging machine

Packaging machines have different variations of vacuuming performance. So, they are divided into:

• Single and double plank. Sealing of the edges of the packaging is carried out on one or both sides;
• Single and double chamber. Packaging can occur both in individual form and paired with another type of product;
• Household and industrial. The first modification is used at home, in catering processes and mini-factories. The second one is used in enterprises specializing in vacuum packaging in large volumes;

The purpose of vacuum forming machines is to form relief forms from sheet plastic, polymer or PVC, with a depth of cavities or bulges up to 500 mm. The body of these units is designed for overall products, which allows you to form a wide range of finished products. The peculiarity of vacuum forming machines is that due to the zonal heating of infrared heating elements (each zone is divided into separate sectors of 0.2 m 2), it is possible to simultaneously carry out forming of varying complexity and with different relief depths on one sheet of raw material. The whole process takes place automatically, after setting all the parameters by the operator using the software.

Vacuum casting machine
plastic mold

This fixture is an accessory for CNC milling machines. As standard, the milling machine has special bolt clamps for the workpiece, but they apply strong point pressure on the material, which can damage it. In order to avoid such nuances, a vacuum table was created that works on the principle of a suction cup, attracting the workpiece to itself with the help of a compressor that pumps air between the surface of the table and the workpiece. Thus, there is a reliable fixation of the material for further milling.

CNC machine with vacuum table

A vacuum press is a device that is primarily designed to process various materials. This process is carried out by applying a film that can have a variety of standards. Often, such devices have, in addition to the main one, a number of additional functions. Such installations have found their active application in various industries. But most often, they are used in large industries. As for those industries where the vacuum press has become an integral element, then for sure - this is the furniture industry. This direction simply cannot function without a vacuum press.

One of the target tasks of a vacuum press is the creation of various figures from wood, plastic and similar materials. Judging by the sales statistics and customer reviews, such equipment is indeed very effective and it will not be difficult to find a use for it. Such equipment is able to easily perform even the most complex functions, and do it very quickly.

It may seem to many that the design of a vacuum press is not particularly reliable. There are a considerable number of reasons for this, the main of which can be called its not quite presentable appearance. But still, it is worth saying that in this design all its elements are purely in their place, which actually allows the device to be used with such efficiency.

The main elements of a vacuum press:

• Carriage - this element can be called a kind of adapter for the interaction of all elements of the system. Many consider this element to be one of the most important, as it performs a huge amount of work.
• The pneumatic vacuum system is one of the fundamental elements of this system, which is responsible for most of the labor-intensive tasks. Often, we are talking about the qualitative distribution of pressure in all directions of this device. This is what allows you to create a high vacuum level.
• Desktop - a certain number of devices can be attributed to this element. All of them, although not so significant, still make a considerable contribution to the overall success of the device.

Above, we have listed only the most obvious components of the vacuum system, which can be seen at a glance. But it is worth remembering that inside such a system there are still a huge number of other elements. Although they are less noticeable, their role in the overall workflow is also very impressive.

The vacuum press is divided into two main categories:

• semi-automatic
• Auto

If the semi-automatic principle of operation implies a certain amount of human assistance, then the automatic one does all the operations on its own. But still, at the moment, the semi-automatic principle of operation is very popular.

But to say something about this is definitely very problematic. After all, everyone has their own tasks that need to be solved. But which press is best suited for this, only you can determine.

Membrane vacuum press

This type of vacuum press is intended for use exclusively in the furniture industry. The main reason for this is the principle of operation of the device, which is designed exclusively for the furniture industry. Diaphragm-vacuum pumps come on sale in a variety of configurations. It all depends on how expensive the option is chosen by the user, and how big the task is.

If we talk about the most significant differences between membrane-vacuum pumps, then they simply do not exist. The only thing is more compact dimensions and higher technical characteristics. As for the appearance of the device, in this respect there are no differences as such. Many at this stage are sure that very soon this category of presses will break out to a completely new level, since it is precisely this category that has the greatest potential.

Now, as an example, we will consider the most compact and versatile version of a vacuum press:

Membrane vacuum press VPR-3000 is one of the best models of vacuum membrane presses in the middle price range. Many users at this stage prefer to purchase this particular vacuum pump model. The reason for this can be attributed to the high level of productivity and quality of the vacuum press. As for the place in the market, now VPR-3000 vacuum presses occupy one of the leading positions in the middle price segment.

This was the main reason to turn our attention to this model of the membrane-vacuum press VPR-3000.

Vacuum press for MDF

Facing kitchen and furniture facades is far from the easiest process that requires special equipment. One of the best types of equipment in this regard can be called a vacuum press for MDF. After going through a similar process, the material gets a completely different look, which means that its durability and density increase several times. If this type of processing is ignored, then later all this can turn into far from the best consequences.
