production costs and speed of production of furniture according to customer designs. The fact is that when making furniture according to individual orders manufacturers are faced with the need to use rounded or non-flat elements such as parts of cornices, various columns, pediments, semi-columns, seats of chairs and chairs, drawers, table tops, oval tables, curved doors, panels, door frames, stairs, shaped details of facade door frames, semicircular bar counters. Orma CVM membrane press. It is to facilitate the work with such parts that a vacuum press is needed, consisting of a table on which the manufacturer places the workpieces, a heater, which is used to heat the film, vacuum system, which ensures uniform pressure due to injection overpressure or atmospheric pressure on the film and membrane.

Membrane vacuum press is a lining machine different surfaces wood and lumber (for example: furniture facades, countertops, doors) films made from thermoplastics such as PP, polyvinyl chloride and ABS. In addition, such equipment makes it possible to veneer wood with synthetic and natural veneer and use thermal printing on ribbed and flat surfaces of wood.

Most devices allow it to be used as membrane, vacuum and membrane-vacuum equipment. That is, you can remove the membrane from this equipment, which is mainly used for finishing with natural wood veneer, and cover surfaces with thermoplastic films without it, which will significantly reduce costs when using the machine. As for the pump, it allows gluing surfaces of different levels of complexity without causing damage to the quality of the cladding.

In addition, the membrane press is very easy to operate, because... With the help of a special remote control, anyone can operate it.

Membrane vacuum press - operating principle

As for the principle of operation of this equipment, it is not complicated - the worker must place prepared furniture blanks with pre-applied glue on its retractable surface, cover it with the film he needs and move it all into the machine. After this, the device can be closed (in the closed equipment the heating process will take place until optimal temperature film) and the film will cover the wood using pressure and vacuum (to make the film fit more tightly, use a membrane).

Vacuum equipment can also be cold, and the main element of such a device will be a vacuum bag, on which the quality of pressing depends. That is why the bag must be made of a material characterized by high strength, elasticity, transparency and repairability. Despite this, some craftsmen make several pressings to create thin material bags made from improvised materials such as air mattresses, films for greenhouses, etc. Professional bags are designed for frequent and repeated use, allowing you to perform quite wide range pressing work, can withstand prolonged and heavy loads, sometimes withstand heat, and therefore are made of PVC (plasticized polyvinyl chloride) and polyurethane. That is why, when choosing the equipment you need, you should take into account not only the dimensions of the workpiece and the lining method, but also the quality of the bag.

In addition to membrane vacuum presses, there are simply membrane presses used for one of the processes: lamination of flat parts, lamination of flat parts and veneering of parts complex shape. Lamination is the process of fusing the outer layer of a material under pressure with molten melamine or paper impregnated with melamine. Thanks to this process, a durable and durable coating is obtained. During the lamination process, urea-formaldehyde glue, dry glue or PVA is applied to a special film (laminated paper, paper impregnated with formaldehyde resins, natural veneer). Cladding is carried out using compressed air and vacuum, and both membrane and non-membrane presses can be used for this process.

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

How the equipment works

Vacuum press for facades has the following components:

• frame, which is load-bearing and has a collapsible type
• desktop, which is also load-bearing. A special clamp-type 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 heating devices electric type. The vacuum press works using automatic control Therefore, performing work on this equipment does not require manual labor. A few operators are sufficient to maintain and run the installation.

Kinds

Today there are several modifications of vacuum presses. They differ in automation and quantity 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.
• semi-automatic. In such devices, opening the installation door, pressing the buttons to start it into operation, then turning it off and removing the workpiece is carried out by the operator himself. The operator must monitor the operation of the installation
• membrane In such a press, the surface is covered with film or veneer. To do this, a material is placed into a heat-resistant membrane onto which glue is first applied. Then the membrane warms up, and a 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 glued to the material
• membraneless. This type of press is used for gluing thicker coatings. This option is not suitable for thin films.

Today, membrane-vacuum presses are used more and more often, compared to old-style equipment. This popularity is due to the fact that much less time is spent processing the material using a vacuum press, but the quality finished product does not decrease, but rather increases.

Presses can also 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 quite high cost due to the fact that large-sized workpieces are processed on it.

3D vacuum sublimation presses are universal electro-mechanical devices. They are needed in order to create souvenir products. In them images are applied to objects in the correct and irregular shape. Such equipment is most in demand when applying various images to ceramic, fabric, and other products. Modern production uses such presses for decoration decorative stones, drawings on protective covers cell phones, on crystals, puzzles.

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

The commercial 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 require further modification. You can immediately assemble products.

Vacuum press operation

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

Silicone membranes for vacuum presses are used when it is necessary to ensure a tight fit of the film. A pump for a vacuum process is capable of forming a vacuum of varying depths, it all depends on the properties of the material. In addition, the membrane must be suitable for a vacuum press. It is worth purchasing it together with the unit.

Types of membranes

Membranes for a vacuum press 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 elastic silicone film or heat-resistant rubber. 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 placed on the back side of the facade) or high-gloss films. Under no circumstances should the final films touch the top heating plate of the press. The membrane is also used when the film dimensions are smaller than the loading table dimensions or when the film thickness exceeds the standard 0.3-0.6 mm.

In most presses, the membrane is installed on a special frame that has a hermetically sealed seal along the upper and lower perimeters. Such a frame can be easily dismantled, thereby turning a two-chamber press into a single-chamber one, and from a three-chamber press into a two-chamber one. 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:

• heats the film more evenly compared to just hot air
• acts as a frame
• prevents film breaks
• prevents air from entering under the membrane, which significantly reduces the amount of defects in production
• transfers heat evenly to the end surfaces of the product.

The film shrinking procedure consists of the following steps:

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

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

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

The membrane is consumables. If all operating rules are followed correctly, it will last approximately 3000 operating 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 a new one made. If you plan the purchase of components correctly and carry out all the work correctly, then the cost of the press will 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 this, 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 the thermal module.

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

Tools that may be needed for work:

• small one-handed corner Grinder with disk diameter 115 or 125 mm welding device
• electric drill
• locksmith kit
• including hammer
• spanners
• pencil
• roulette.

When everything is collected, you can start working. First you need to cut steel profile on the parts strictly according to the cutting map. Place them on a flat surface according to the design, level and secure with clamps. Next, start welding the parts. Welding seams need to be cleaned with a grinder and a grinding wheel. After this, you can drill all the necessary holes, prime the part and paint it.

The table assembly procedure is perhaps the most important undertaking. During design, you will determine its dimensions and material. It is imperative to consider a method for fixing and sealing the connector elements in order to maintain the internal vacuum. Vacuum table is a structure that consists of:

• baths
• clamping frame
• clamps.

The dimensions of the vacuum bath influence the number of workpieces placed in it. Experts advise making a bath approximately 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 top part facade and the film with which it will be covered. The bottom of the bath can become steel sheet, the thickness of which is 2 mm, and the frame can be made from profile pipe.

You can also create a clamping frame and clamps from a profile pipe; its dimensions must completely match the dimensions of the bathtub. To hold the clamping frame in a raised state, it is necessary to install 4 gas lifts and make sure that they can hold it. The clamps ensure that the film is held securely and airtight during pressing. The upper frame must be pressed tightly and evenly against the perimeter of the bathtub. In fact, the clamps are eccentrics. They can be created from rolled steel. They need to be mounted at 8 in advance drilled holes in a vacuum table.

In case the table does not have perfect 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 covers the surface of the workpiece. During the system installation process, pay attention to the following points:

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

The thermal module is heating device, which allows you to evenly heat the film to the desired temperature and hold it for a certain time. The frame for it is made from steel pipe with a section of 20 by 20 mm. The housings of the profile wheel supports and L-shaped handles for movement along the module rails need to be welded to the frame. Ball bearings can be used as wheels. After this, the frame must be sheathed with sheet steel and reinforced with aluminum blind rivets. You need to make openings on the side of the casing rectangular shape for observation windows and install silicate glass, darkening them in advance with a tinting film.

To improve reflectivity, the inside of the thermal module must be equipped with aluminum foil. Next comes the installation of heating elements. Linear KGT (quartz halogen thermal) lamps 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 symmetry of the three-phase load and the possibility of zone control of groups of lamps.

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

Furniture production in our country is very well developed. There are many companies that manufacture cabinets, tables, furniture, 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, furniture should not only be of good quality, but also beautiful. In order to achieve this, you must, of course, first of all use high-quality machines in production.

Machines for making blanks

At specialized enterprises the following is used:

Format machines. This equipment is intended for cutting MDF boards or chipboard.

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

Presses for the production of curved facades.

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

also in furniture production A vacuum membrane press is required, which will be discussed in this article. This equipment is used for covering the facades of cabinets and furniture with decorative PVC film or veneer. Modern machines This type has a fairly simple design and is also easy to use.

Basic design elements of a vacuum machine

This type of equipment is not very complicated. Any such machine consists of five main elements:

• A table on which furniture pieces are laid out. Its surface is usually sheathed metal sheet or thick tin.
• Vacuum pump.
• Pressure frame. This element of the press is also made of durable metal.
• Heating installation. Different presses are used different types this equipment. Heating unit can be infrared or contact.
• Actually the press itself. It can be made in the form of a hinged or roll-on lid.

Additional design elements

Such equipment is called vacuum because the film is tightly pressed to the workpieces in it by completely pumping out the air from under it. At the end of the table in such equipment there are shafts (one or several) for rolls of PVC film. In order for the workpieces to fit as tightly as possible with the material, they are placed on the table on special substrates. At MDF finishing or Chipboard veneer In addition, special glue is used. The press is controlled using an automatic remote control. At the same time, the operator has the opportunity to manually configure the equipment.

Types of presses

Enterprises currently use only two main types of such machines:

Actually vacuum presses. Used for finishing furniture pieces in a gentle way. Such installations can provide a pressure of no more than 0.95 kg/cm2.

Vacuum with additional pressure. Such equipment is much more expensive. Moreover, it can provide pressure up to 8.5 kg/cm2.

The first type is usually used for gluing PVC film or for veneer finishing simple blanks. Vacuum presses of the second type are used for cladding furniture parts made of MDF that have a complex configuration.

Membrane for presses

Both types of vacuum machines are usually supplemented with a special membrane. It is most often used when gluing workpieces with veneer as an additional “press” that prevents unwanted movements during work. The membrane is also 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 an area 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 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 a press allows you to:

clad parts of very small sizes;

reduce the amount of film waste.

Film finishing

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

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

Blanks are placed on the substrates: cabinet doors, drawer trims, parts of the facade, etc.

The table with workpieces is completely covered with PVC film, unrolled from the shafts.

A clamping frame is lowered onto the film around the perimeter, tensioning and straightening it.

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

The operator sets the required temperature and pressure values ​​on the control panel and turns on the equipment. After this, 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 allotted time has elapsed, the operator turns off the press and tilts it back (or moves it away).

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

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

Many may think that the design of a vacuum press is not particularly reliable. There are a number of reasons for this, the main one of which is its not entirely presentable appearance. But still, it is worth saying that in this design all its elements are strictly in 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, since 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 labor-intensive tasks. Often, we are talking about high-quality pressure distribution in all directions of a given device. This is what allows us to create a high vacuum level.
• Desktop – this element can include a certain number of devices. All of them, although not so significant, still make a significant contribution to the overall success of the device.

Above we have listed only the most obvious components of the vacuum system, which can be noticed at first glance. But it is worth remembering that within 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.

Vacuum press is divided into two main categories:

• Semi-automatic
• Auto

If the semi-automatic operating principle involves some human assistance, then the automatic one performs all operations independently. But still, at the moment, the semi-automatic operating principle is very popular.

But it is definitely very problematic to say something about this. After all, everyone has their own tasks that need to be solved. But what kind of press is for this? fits better, only you can determine.

Membrane vacuum press

This type vacuum press is intended for use exclusively in the furniture industry. The main reason for this is the operating principle of the device, which is intended exclusively for the furniture industry. Diaphragm vacuum pumps are available for sale in a variety of configurations. It all depends on how expensive the user has chosen and how big her tasks are.

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 specifications. Concerning appearance devices, then in this regard there are no differences as such. Many on at this stage We are confident that very soon this category of presses will explode into new level, since it is she who has the greatest potential.

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

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

This is exactly what became main reason to turn your attention to this model of the VPR-3000 membrane vacuum press.

Vacuum press for MDF

Cladding kitchen and furniture facades is not the easiest process, which requires special equipment. One of best views equipment in this regard can be called a vacuum press for MDF. Having gone through a similar process, the material gets a completely different look, which means that its durability and density increases several times. If this type of processing is ignored, then subsequently all this may turn out to be far from the best consequences.

Another direction in the work of vacuum presses is the lining of various types of materials using high-gloss film. This type of processing makes it possible to raise the quality level of the material. Absolutely all elements that have undergone such processing become protected from the influence of the outside world. As for heating such equipment, this process is also far from the easiest. A significant role in this is played by special heating elements, which are actually intended for this.

Vacuum presses for facades

The facade cladding process combined a number of stages, each of which is responsible for the solution specific task. Many users say that the facade vacuum press process is one of the most effective at this stage. Already at the moment, a huge number of different enterprises are ready to pay a lot of money to get equipment of this type.

But it is worth understanding that a vacuum press for facades is only one subcategory of a vacuum press. But this does not at all prevent him from gaining more and more popularity and reaching an ever higher level.

As for performance indicators, in this regard everything is no worse. High level productivity also depends on how carefully such equipment is treated. But in fact, this is far from the end of the development of this industry and in the future everything can change very much.

But if there are enough advantages in such systems, then it is worth noting the fact that such systems also have their disadvantages. One of them can be called cooling of average quality. In certain situations, this element may not be the most reliable, which is why they try to take care of it in advance.

Where to buy a vacuum pump

But you shouldn’t pay all your attention to just two aspects that everyone considers the most important. Indeed, in addition to characteristics and cost, there are a considerable number of factors that play an equally important role. One of these indicators can be considered stability, on which a lot also depends in the work process.

No less important point You can name the brand that you are going to buy for yourself. After all, by purchasing devices from a trusted person, you can be sure that in the end you will be able to get your money back.

Now, we will look at several of the most reliable manufacturers of vacuum pumps:

• Atlas Copco is one of the oldest manufacturers, which has long ago managed to establish its place in the market.
• Edwards is a lesser known company. But still, she is in considerable demand in her circle, which is why many pay attention to her.
• Becker - This manufacturer pays the greatest attention to the quality of the products it sells. Of course, defects may occur during the manufacturing process, but all this can be corrected with the help additional equipment, which will not leave you in trouble.

Vacuum presses are designed for lining furniture parts, kitchen facades, doors and insert panels with PVC films and veneer. Suitable for molding composites with a relief surface.

The KAMI company sells equipment with delivery throughout Russia. Our website offers membrane-vacuum units that are distinguished by their performance and reliability. Thanks to these characteristics, the devices have gained wide popularity among professional furniture makers.

Design features of a membrane-vacuum press

The units have a simple but functional design, the main components of which are:

• Work table for the processed material;
• Vacuum pump;
• Pressure frame;
• Heating device – infrared or contact;
• Press;
• Membrane – allows you to work with materials that are permeable to air.

The operation of the installation is based on vacuum technology and a thermal system. Temperature effects make it possible to perform many tasks: from cladding furniture, manufacturing bent-glued products to cladding the surface of car interiors, sea and air transport composite materials. Vacuum technology is in demand not only in furniture production, but also in other industrial sectors: machine, aircraft and shipbuilding.

Thanks to the vacuum principle of operation, a tight fit of the film to the body of the product is achieved by sucking out air from under facing material. Special backings help glue the film to the ends.
