Introduction

Screw tip assembly is one spare part of injection unit.  Which normally contains tip, non-return valve and seat valve.

Types

Depends on various polymer application, we offer by below types of screw tips

· Free flow valve type

· Clutch valve type

· Mixing Type

· Ball check valve type

Also for some special polymers like PVC, PC, LSR, we offer specialized designs and treatment

Material Selection

Screw Tip assembly normally wear fast than screw barrel, which require higher quality material and treatment to ensure similar function time of screw barrels, we offer material in Bimetallic, Through Hardened, PM steels and all kinds of Surface treatment like Chrome-plating, PVD coatings.
