Usually the screw can be divided into common type, gradient type, mutant, mixing type, separate type, shunt and a variety of barrier-type, pin type, DIS open bar shunt
PA low viscosity crystalline plastics, high temperature, melt speed, self-lubricating, water flow is good and easy salivation, temperature-sensitive and easy cold head, moisture Big Easy
PPO is a non-crystalline material, melting hard, easy tying on the shear-sensitive, readily biodegradable.
PBT + GF special screw
PBT resin is saturated, semi-crystalline materials, high melting, crystalline rapid curing fast, easy to break down, and the need for pressure-sensitive glass fiber.
Marbling special screw
Two options: A: only need to replace the marbling effect of the screw; B: replacement of marble screw barrel package, the control computer to modify the program or increase the electrical plug.
Bakelite, urea group dedicated screw barrel
Materials useful in hot oil loop heating, double screw recommendation grade C alloy; old machine can also be converted into a plastic Bakelite Injection
