PET material injection molding process technology

PET material injection molding process technology

PET injection molding application
Automotive area (such as automotive lamp mirror frame), electronic area (like motor housing), electronic connector, relay, switch…), Industry application( Pump housing, handcraft equipments).

PET injection molding process condition:
Dry the PET material before molding, as PET hygroscopicity is very strong, when dry the PET material, the temperature condition should be 120~165 degree for 4 hours, and the humidity should be smaller than 0.02%.
Melt temperature: 265~290 degree
Mould temperature: 80~120 degree
Injection Pressure: 300~1300 bar
Injection Speed: Can use high injection speed on the basis of not embitter the material.
Runner and injection gate: use normal injection gate, gate size should be 50%~100% of the plastic thickness.
 
For PET material with firber glass, under the high temperature, it is very easy to bend, we can increase its crstal degree through adding the crystal agent.
