WEXCO "666" General Purpose Injection and Extrusion Barrels

WEXCO "666" Barrels

High-Performance Bimetallic Injection and Extrusion Barrels

WEXCO's "general purpose" bimetallic barrels!

Primary Applications:

For Extrusion and Injection Molding using Non-filled, Non-corrosive Polymers

If you are processing a variety of polymers that are only mildly abrasive (i.e. unfilled) and not corrosive, then consider WEXCO "666" barrels as the processor-preferred "general purpose" choice. They are also a very cost-effective replacement for tool-steel barrels, especially in sizes of 2 inch bore and above.

The “technical stuff”:

WEXCO "666" general purpose plasticating barrels are recommended for applications that process mildly abrasive materials (i.e. unfilled, non-corrosive polymers). The bore protection in WEXCO "666" barrels has a hardness range of Rockwell C 60-65, and consists of a nickel-boron base iron with a high hardness, martensitic structure in cementite matrix. It has excellent abrasion resistance and a low friction coefficient (0.07µ) for prevention of screw galling.

Compared against "nitrided" barrels, WEXCO 666 typically provides a three to four times longer service life, and up to 10 times longer service life when used to process mildly corrosive polymers.
