摘要：
A plasticizing barrel for a plastics processing machine includes a body having a hollow cylindrical configuration and defining an axis; and a coating formed on an inner wall surface of the body and including at least one groove extending in axial direction of the body. The coating, e.g., a wear-resisting protective layer, may be produced through centrifugal casting, whereby the grooves are formed by projections of a negative mold inserted in the hollow-cylindrical body.
