How to Choose Thermoforming Machine Thickness and Cooling System

How to Choose The Sheet Thickness and Cooling System of Automatic Plastic Thermoforming Machine

Sheet Thickness

Automatic plastic material thermoforming machine is our common machine, the thickness of the sheet of automatic thermoforming machine is usually 0.12-2mm, the sheet is from a wide range of sources, such as PS, PET, PVC, PE, recyclable materials and so on, and the main products are pharmaceuticals, hardware, cosmetics, food and so on;

The thickness of thick sheet automatic plastic thermoforming machine is 1.5-8mm, and the main products produced are light box advertisement, back shell of home appliance, refrigerator inner liner, bathtub and so on. Some products can replace the injection molding products, but compared with the injection molding process, the mold cost of the thick sheet automatic plastic thermoforming machine is lower, the mold production time is shorter, and the efficiency is higher than the injection forming machine.

Cooling System

When choosing automatic plastic absorbing machine, you must fully consider the characteristics of your products. If you have any questions during the purchase process, you should make more references. Why is cooling important for the production of automatic themoforming machine?

As we all know, in the molding process of automatic themoforming machine, it is necessary to make the plate contact with the mold for vacuum molding. The mold repeatedly comes into contact with the heated sheet and the accumulated heat during the operation. When the temperature reaches a higher temperature, it is necessary to wait for the mold to drop to a lower temperature before production can continue. At this point, a cooling system will be used to accelerate mold cooling.

During the product molding process, the fully automatic themoforming machine has a cooling process to enhance the strength of the product and help it to be formed. Built-in cooling structure of the mold is the ideal purchase nowadays, the product in contact with the mold both inside and outside need to be cooled.

Semi-automatic themoforming machines are mainly water-cooled and air-cooled, which cools the paper by spraying water mist or blowing cold air. Although spraying water mist and blowing cold air can achieve the cooling effect, the cooling speed from outside to inside is slow, but it is characterized by wide material adaptability. Non-metallic materials such as plaster and wood can be used.

Maintenance of fully automatic plastic themoforming machine:

1, lubrication: all columns, chains and bearings should be kept well lubricated. Running without lubrication will seriously damage the machine and cause deformation of the column.
2, water filter, oil mist: observe and record the indicators, regular refueling and water replacement.
3、Keep the working environment clean and sanitary. Waste material around the body, oil inside the machine, etc. need to be dealt with every shift.
