Recently, a friend in the industry asked me what positive and negative pressure vacuum blister machine and negative pressure vacuum blister machine, and what are their uses? Below I will give you a detailed analysis of the difference between the negative pressure vacuum blister machine and the positive and negative pressure vacuum blister machine:
The difference between the negative pressure blister machine and the positive and negative pressure blister machine is that the negative pressure blister machine has only the function of blister, and the positive and negative pressure blister machine has the functions of blowing and blister; the negative pressure blister machine forces the positive and negative pressure to suck The cost of the molding machine is lower and the structure is simpler.
The principle of blister forming machine: blister forming is also called thermoforming. This kind of forming process mainly uses the vacuum produced by the vacuum pump to suck the thermoplastic plastic sheets such as PVC, PET, PETG, APTT, PP, PE, PS, etc. Molded into various shapes of vacuum covers, or attached to the surface of various shapes of products. According to the thickness of the sheet, the blister is divided into thin blister and thick blister.
The main structure of the machine is composed of feeding, drawing, upper and lower electric heating furnace, lower gate, multi-functional adjustable size, lower mold plate, upper mold, upper gate, knife gate, slicing, placing film, and vacuum equipment. ；
The common products of thick blister include: household appliance inner 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 liner, etc.
Alright, the above is the difference between the negative pressure vacuum blister machine and the positive and negative pressure vacuum blister machine that I introduced for you? related information! I hope to be helpful! Technical support: Mingpinhui Network
