Recently, an industry friend asked me what positive and negative pressure vacuum suction molding machine and negative pressure vacuum suction molding machine, what are their uses? Below I give you a detailed analysis of the negative pressure vacuum suction molding machine and negative pressure vacuum suction molding machine what is the difference:




	
The difference between the negative pressure blister machine and the positive and negative pressure blister machine is that the negative pressure blister machine only has the blister function, and the positive and negative pressure blister machine has the functions of blow molding and blister. The negative pressure blister machine forces the positive and negative pressure blister machine to have lower cost and simpler structure.




Principle of Blister Forming Machine: Blister forming is also called thermoplastic forming. This forming process mainly uses thermoplastic plastic sheets such as PVC, PET, PETG, APTT, PP, PE, PS, etc. after vacuum generated by vacuum pump to form vacuum covers of various shapes through molds or stick to the surfaces of products of various shapes. According to the thickness of the sheet, the blister is divided into thin sheet blister and thick sheet blister.


The main structure of the machine is composed of feeding, pulling, upper and lower electric heating furnace, lower gate, multi-function adjustable size, lower mold plate, upper mold, upper gate, knife gate, slicing, sheet release and vacuum device, etc;


The common products of thick blister are: household appliances inner container shell, luggage, display rack accessories, decoration, car interior, bumper, fender, beauty equipment, light box shell, toy car shell, industrial panel, advertising light box, blister LOGO, bathroom products, refrigerator inner container, etc.
