Special designed points for PET(for HI-P series injection molding machine)

Characteristics of PET resin

1. melting point: 250℃-260℃, molding temperature scope of PET is from 255℃-290℃, improved GF-PET can reach 290℃-315℃.

2. Low viscosity degree.

3. Strong moisture absorbing ability.

Our machine’s special design for PET

L/D:25, this is the standard parameter of our PET series injection molding machine.
Enlarged screw diameter and length.
Increased oil pump’s power.
Increased heating ring’s power.
