Inspection of bimetallic screw barrel

Bimetallic process is crucial, it’s very important the bimetallic alloy is tightly attached to bimetallic screw barrel, no split, no insane crack.

At EJS, we use centrifugal casing machine to do bimetallic barrel while Kennametal Stellite bimetallic welding machines are used for bimetallic screw.


I don’t know component information of your bimetallic screw barrel, but I do know we buy X800 bimetallic screw barrel from Xaloy, can you do that?

When you tell us the alloy type from another famous company, such as Xaloy, Bernex, EJS is able to identify the equivalent alloy, please do not hesitate to contact your exclusive sales representative for further communication.
