What Are The Points To Pay Attention To When Operating The Vacuum Laminating Machine?

How to use the vacuum laminating machine

1. Before work, check whether the pressing device and each rotating part are in good condition, clean up the dust and scum in the workbench, and prepare necessary materials such as product pads.

2. Turn on the heating switch and vacuum switch, and set the temperature, vacuum degree and preheating timing according to the needs of the production process. After turning on the vacuum pump for the first time or shutting down for a long time every day, turn on the vacuum pump after turning on the switch twice, which is conducive to the normal use of the vacuum pump.

3. Polish the surface of the workpiece to be coated smoothly, and spray the special PVC glue evenly.

4. Place the prepared workpieces reasonably on the special bottom frame in the suction covering station, lift up the film pressing device, lay the PVC film, and lock the film pressing device. The PVC diaphragm is required to be flat and free from damage and air leakage.

5. Move the suction cover to the heating box, and heat the PVC film according to the preheating timing. When the set time is up, the vacuum pump will automatically turn on for suction and cover. After the suction cover is in place, continue to heat for 30S~90S (this parameter can be controlled by yourself ), move out of the suction and cover station, and take out the workpiece after a little cooling.

6. Carefully and carefully record the process parameters used in the production process of various PVC materials and special glues, which will be helpful to future work.

7. When the machine is found to work abnormally, the power supply should be turned off immediately and the supervisor in charge should be notified.

8. During work, the operator shall not leave the machine tool, and the power supply shall be turned off in time when the work is completed.

What to pay attention to when operating the vacuum laminating machine

1. Medium-hard PVC film should be used as far as possible, and there will be no rebound phenomenon after being sucked and covered. If the product is turned inside out, it is caused by the different tension of the PVC film during the compound processing.

2. Adhesives cannot rebound in the production of diaphragms, so the quality of special adhesives must be good. If the adhesion is not strong, it means that there is a problem with the adhesive.

3. Check and adjust the temperature and timetable setting values according to the thickness of the film material, and place the appropriate distance according to the thickness of the processed plate when multiple pieces are combined.

4. Before turning on the heating cover, check whether the material pressing rack is locked, whether there are objects on and around the guide rail and whether the hands of personnel leave.

5. During the working process of the machine, it is strictly forbidden to stand around the machine, let alone put your hands on the guide rails and equipment, to prevent the machine from automatically returning to the heating cover and hurting people.

6. It is strictly forbidden to place products and other objects on the heating cover, and do not disassemble the safety cover and other protective items at will.
