The difference between a negative pressure -sucking machine and a positive and negative pressure suction machine is that the negative pressure -absorbing machine only has a planting function, and the positive and negative pressure plastic sucking machine has the function of blowing plastic and plastic. The cost of plastic machines should be low and the structure is simpler.

Principles of sucking molding machine: Breeding molding is also called hot -shaped molding. This molding process is mainly PVC, PET, PETG, APTT, PP, PE, PS, etc. generated by vacuum pumps.

Thermoplastic plastic sheet is vacuumed into various shapes, or the surface of various shapes is attached to various shapes. Based on the thickness of the piece, it is divided into thin pieces of suction and thick slices.

The main structure of its machine is consisting of feeding, pull -up, power -up heating furnace, down gate, multi -function adjustable size, lower mold disk, upper gate, upper gate, knights, slices, fillets and vacuum devices, etc. It
