Alloy Screw and Barrel for Injection Molding Machine

Alloy Screw and Barrel for Injection Molding Machine
Alloy Screw and Barrel for Injection Molding Machine
Product Code : 51
Product Description

Alloy based metals like nickel alloy, tungsten carbide alloy and ferrous alloy are used for its fabrication. Exceptional hardness level, rust protection capacity, wear protection ability and high temperature proof design are some of its main attributes. The offered barrel with bimetallic characteristics is widely used for processing of PPO and fluoride plastic. Good plasticizing effect and long working life are some of the main reasons behind its huge popularity in injection molding industry.
