What is Bimetallic Conical Twin Screw for Extrusion?

Compared to the single extruder, conical twin screw has two intermeshing identical screws encased in a matching barrel

For Bimetallic, it means that bimetallic conical twin screw is made of two alloys metals. The first metal is the base material and the second metal is the coating material. So the bimetallic conical twin screw for extrusion has better corrosion and abrasion resistance, is more durable, and lasts longer than non-bimetallic ones.

How to make the bimetallic conical twin screw for extrusion?

Barrelize use PTA welding machines to spray and weld the special ni-based alloy powders on the screw's ridge. So it can protect the screw flights and postpone the wear after we apply an abrasion and corrosion-proof coating layer on the top of the screw flights.

What 's the specification of a bimetallic conical twin screw for extrusion?

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 bimetallic conical twin screws for extrusion: high corrosion resistance, high wear resistance, and high temperature resistance, more durable, and longer lifetime.

What is the application of bimetallic conical twin screws for extrusion?

Additive plastic materials with less than 30% glass fiber, nylon, PC, PPA, te, fire PC+ glass fiber, Nylon + glass fiber.
