china pet prefrom injection molding machine .
PET injection molding machine chemical name is polyethylene terephthalate, also known as polyester. At present, GF-PET is the most widely used among customers, mainly the bottle embryo. PET has good rheological properties in the molten state, and the influence of pressure on viscosity is greater than that of temperature. Therefore, the main way to change the fluidity of melt is from pressure. 330T multi-cavity bottle embryo injection molding machine is a professional PET bottle embryo injection molding machine. It uses specially designed screw and high-torque glue melting motor to facilitate the plasticization of PET raw materials and meet the ejection device of PET product production. It uses high-power motor-pump system to achieve a shorter cycle.pet prefrom mold injection molding machine.
