What Is a Blister Machine?

Blister machine, also known as thermoplastic molding machine, is a machine that absorbs heat-plasticized PVC, PE, PP, PET, HIPS and other thermoplastic rolls into various shapes of advanced packaging boxes, frames and other products. By using the vacuum suction generated by the vacuum pump, the thermoplastic plastic sheets such as PVC and PET after heating and softening are blistered into various shapes of vacuum covers, blister trays, blister shells, etc. through a mold.

Principle of blister molding machine: blister molding is also called thermoplastic molding. This molding process mainly uses

When producing the first product, set the heating time to more than 1.5 times of the time required by the process, start the lower gate, and observe the sheet heating In some cases, when the heating zone of the sheet material reaches the molding temperature, jog the sheet in advance to move the sheet out of the heating region under the driving of the chain, enter the molding action, and modify the set number of heating time.

20. After the sheet is shaped and cooled, it is taken out of the molding area by the chain and enters the cutting area. At this time, the knife gate should be closed, the receiving box should be moved, and after adjusting the cutting position, the receiving box is positioned and the knife gate is opened. .

21. When the blister machine is in automatic production, the operator should check the product quality to see if the temperature meets the product quality requirements, adjust the temperature, and then check the details to check whether the uniformity of the film formation of the production variety is consistent and perform local temperature adjustment. To maintain the quality requirements of the product.

22. Secondary upper mold: used to protect the product from demoulding when the product is not deformed, crack-free, fragile, and difficult to demold. Function setting: The upper mold function is selected in the second upper mold. When the upper mold is lowered to the surface of the product, the cold wind stops and the bottom wind starts to blow. Adjust the time for the second upper mold to be down: about 2 seconds less than the time when the water spray time counts up and the cold wind counts up. If the upper mold comes down too early, increase the use of water spray, otherwise, reduce the spray time.

23. Vibration demolding: It is usually used in products with high or deep molding and difficult to demold. The button of vibration demolding is selected to be on, and the bottom blowing time is set to more than 2 seconds, which is set according to the number of product demoulding vibrations. The more the number of vibrations, the longer the bottom blowing time is set. Open the control box on the bottom right, there are two 10-second time systems. The time system on the left controls the time of the lower mold, the right controls the total time of the next cycle of the mold plate, and adjusts the limit valve according to the reaction of the mold plate up and down, and performs electrical combination to achieve the purpose of vibration.

24. Electric synchronous mold adjustment: According to the degree of combination of upper and lower molds, when the function button system is selected to rise, the jog adjustment will overshoot, and the upper mold will rise, otherwise it will fall.

25. Pull in advance: Start the lower brake within the heating time, observe the heating of the sheet. When it meets the requirements of product molding, click this button to make the sheet out of the heating area under the lead of the chain and enter the molding action.

26. Lower brake: This function can be operated in both manual and automatic states. It can be adjusted locally when manual, and used to observe the heating status of the sheet when automatic.

27. Stop gate: In the automatic state, according to the needs of product molding, it is not necessary to close the gate when it is used.
