Vacuum curved surface Vacuum Forming machine, also known as vacuum laminating machine, is a mechanical device that uses vacuum negative pressure technology to coat PVC film or other materials on workpieces of various shapes.
After improvement, the vacuum curved surface Vacuum Forming machine can coat a variety of materials, including PVC film, thermal transfer, Boeing film, solid wood veneer, paint paper, etc. In addition, it is also suitable for the production of polymer doors. It has multifunctional characteristics and is widely used in the furniture and home decoration industry. Modern vacuum Vacuum Forming machines are highly automated and easy to operate.

It should be noted that the size of the station can be customized according to the size of the workpiece and the width of the PVC film, and the equipment specifications of different manufacturers may vary.
1. The equipment should be installed in a clean, dust-free, flat-ground workshop, and can be moved by forklifts and other tools.
2. After the equipment is properly placed, the accessories should be properly installed and the anchor bolts should be adjusted to ensure that the equipment is placed horizontally and the forces of each component are balanced so that the moving parts of the equipment can run smoothly.
3. The equipment uses a 380V power supply (three-phase five-wire system), and the cross-sectional area of the power cord is not less than 6mm2. In order to ensure the safety of the equipment and personnel, the equipment should be reliably grounded, and the cross-sectional area of the grounding wire should not be less than 2.5mm2.
4. Adjust the vacuum gauge pointer so that the vacuum degree is between -0.06Mpa and -0.09 Mpa. Adjust the temperature control table and set the temperature between 180буC and 220буC. These process parameters can be fine-tuned according to actual conditions (such as PVC diaphragm, special laminating glue).
5. Connect the lines of the external components and the electric control box, and connect the vacuum pipeline. After confirming that the power supply voltage is correct, you can power on the machine for testing.
6. Turn on the electric heating switch to power on the equipment for heating. Observe whether the three-phase current is balanced and whether the heating control is normal through the ammeter on the panel.
7. Let the equipment run at no load and check whether the electrical control system and mechanical moving parts are normal and reliable.
8. Press the vacuum pump switch once or twice to check whether the motor rotates in the correct direction.
1. The equipment should be operated by a dedicated person. The operator must receive training, be familiar with the equipment performance, master the laminating process, understand the operating procedures, and pay attention to safe production.
2. Turn on the heating switch and vacuum switch, and set the temperature, vacuum degree and preheating timing according to the production process requirements. Before starting the vacuum pump for the first time, you should press the switch twice to help the normal use of the vacuum pump.
3. Polish the surface of the workpiece to be coated and evenly apply the PVC special glue.
4. Reasonably place the workpiece on the special bottom frame in the suction and coating station, lift the film pressing device, lay the PVC film and fix it. The film is required to be flat, without damage and air leakage.
5. Move the suction and coating station to the heating box, heat the PVC film according to the preset time. When the time is up, the vacuum pump automatically starts for suction and coating. After completion, continue heating for 30S~90S, take out the suction and coating station, and remove the workpiece after cooling slightly.
6. Carefully and in detail record the process parameters of various PVC materials and special glues in the production process, which will be beneficial to future work.
7. If you need to know more about the process parameters and operation methods of veneer lamination, thermal transfer, etc., please consult the after-sales service department or technicians.
1. Check the density and milling quality of the board. Poor-quality boards or improper milling may cause the surface of the product to be uneven after lamination.
2. It is recommended to use a medium-hardness PVC film to avoid rebound after suction lamination. If the product turns outward and rolls inward, it may be due to inconsistent tension during the composite processing of the PVC film.
3. The adhesive produced by the film should not have rebound phenomenon. The quality of the special glue is directly related to the quality of the product. To solve the problem, suction lamination can be performed once before spraying glue to eliminate insufficient pressure or milling quality problems. If the phenomenon of turning inward and rolling outward occurs, it indicates that there is a problem with the PVC film. If the bonding is not strong, it indicates that there is a problem with the adhesive. Only after everything is normal can the glue be sprayed and formal production can be carried out. If you have any questions, please consult the after-sales service department or technicians.
1. Keep the work surface clean to avoid dust, wood chips and other debris falling into it. Clean the air filter regularly to prevent clogging and affect product quality.
2. After the first cumulative use of 100 hours, the vacuum pump oil should be replaced. The oil level should be checked weekly thereafter. When the oil level is lower than 1/3 of the dipstick, it should be added in time. It is recommended to use 1# vacuum pump oil. If oil stains are found, it should be replaced immediately. Before replacement, the vacuum pump should run for 30 minutes to make the oil thinner, then stop the pump, drain the old oil, and then open the air inlet to run for 1-2 minutes. At this time, a small amount of new oil can be slowly added to replace the stored oil in the oil chamber.
3. After the equipment stops running, the clamping device of the PVC diaphragm should be loosened. During normal operation, all protective covers must not be removed to avoid accidents.
4. Pay attention to the operating status of the equipment during production and deal with problems in a timely manner. When electrical failures are involved, they should be handled by professionals.
