What are Bimetallic extrusion screws?

Barrelize Bimetallic extrusion screws are made of two alloy metals. The first metal is base material and the second metal is the coating material. So the bimetallic extrusion screws have better corrosion and abrasion resistance,more durable, and last longer than non-bimetallic ones.

How to make the bimetallic extrusion screw with two metals ?

Barrelize uses PTA welding machines to spray and weld the special ni-based alloy powders on the screw's ridge, which greatly provide high surfacing bonding strength, and improve the resistance of the bimetallic extrusion screw.

What 's the specification of Barrelize Bimetallic extrusion screws ?

For the first base material, you can choose 38CrMoALA and 42CrMo. The second metal is ni-based alloy usually. Barrelize can make the thickness of the bimetallic layer : 1.5-2mm. The hardness can reach HRC53-HRC56.

The general advantage of Barrelize bimetallic extrusion screw: are high corrosion resistance, high wear resistance and high temperature resistance, more durable, and longer lifetime.

What is the application for Barrelize Bimetallic extrusion screws?

Additive plastic materials with less than 30% glass fiber, corrosion formula, regrinding resin, calcium powder filling, additive fireproof materials, nylon, PVC, PC, PPA, PPO, PPS, PA6T, LCP, ABS, bakelite, fire PC+ glass fiber, Nylon + glass fiber.
