What should your mold temp be set at to mold poly ethylene?
Mould temperature has a big effect on PE product. If mould temp is high, the product shrinkage will be big and if the temp is low, the innerstress will be high, thr product will before easily. Usually for LDPE, the mould temperature is 35～60℃ for LDPE and 50～80℃ for HEPE. If you want to know more,pls contact Sino Mould (email@example.com) ...
