Product Details

PET Screw for Injection Moulding Machine and Extruder

PET is commonly used raw materials for general plastic bottled beverages. They have features of  low viscosity, good flow ability, large specific heat capacity, and easy to stick materials. The molding temperature is high, but the material temperature adjustment range is narrow and the process ability is poor. If the material temperature during PET injection molding is too high, When the screw shearing is too large or the rotation speed is too fast, acetaldehyde is easily generated and the acidification occurs, so ordinary screw need to be chrome plated and it is necessary to add an anti-flow device in the nozzle.
