DESCRIPTION
HI-SV/P168 PET Preform Injection Molding Machine adopted special prolonged screw, three R/D of screw, 21:1 / 23:1 / 25:1, are available, this machine is used to produce PET performs with weight 5g-120g, neck size 8mm to 80mm.
HI-SV/P168 PET Preform Injection Molding Machine is the type of fully-automatic machine, being provided with high efficiency, high reliability, high speed, low noise, low power consumption and other advantages.
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.

Injection Unit
This unit is composed of plasticizing, material feeding, injection base, pre-plasticizing motor, whole forward-backward cylinder etc., thereinto, injection and mold moving is driven by oil cylinder, and the plasticizing will be realized by screw which is actuated by oil motor directly. Our machine’s injection unit with the advantages as compact structure, reasonable composition, equal plasticizing, high injection press and high speed, very suitable for producing high quality products.
