Characteristics of screw of PET special injection molding machine
What is the difference between the screw of PET special injection molding machine and others?
1. High melting point, low viscosity, strong adhesion to metal, easy to hydrolyze;
2. Hydrophilic, sticky material is more sensitive to water at high temperature.
Powerjet PET Preform Injection Molding Machines are specialized for different sizes of PET preforms. With PET special screw, it highly increases the plasticizing speed and shot weight.
PET screw highly increases the plasticizing speed and shot weight, lowers the plasticizing temperature and AA value, also achieves better products transparency.
