  Introduction Selecting a screw and barrel supplier is one of the most consequential procurement decisions a plastic processing plant makes, yet it's often treated as a routine purchase. The wrong choice can mean inconsistent output, premature wear, and unplanned downtime, while the right partner — often a specialized Bimetallic Screw Manufacturer — can improve line efficiency for years. This article walks through the practical factors procurement managers and plant engineers should weigh before placing an order, from material compatibility to after-sales support. Start With Your Application, Not the Catalog Understand What You're Processing Before comparing suppliers, define the material you run most often. Virgin resins behave very differently from glass-filled, mineral-filled, or recycled compounds in terms of abrasiveness and chemical reactivity. This single factor determines whether a standard screw, a nitrided screw, or a bimetallic screw is the appropriate specificatio...

A bimetallic barrel is made up of two metals or alloys. As the name suggests, in a bimetallic barrel, two metals are fixed together. A bimetallic barrel is used to increase the life of the entire screw and barrel. That is because a bimetallic barrel works better than a mono-metallic barrel. Bimetallic barrels are made in two metals - the base material and the coating material. That is why a bimetallic barrel lasts longer than a mono-metallic barrel. There are multiple applications of a bimetallic barrel. It can be used for corrosion formula, regrinding resin, calcium powder filling, additive fireproof materials, and additive plastic materials with less than 15% glass fiber. Special machines are adopted for hard-facing, with the alloy thickness over 1.5 mm, providing high surfacing bonding strength, dense textile & effectively improving the resistance of the barrel to abrasion, high temperature & corrosion. It helps extend the service life of the bimetallic barrel. The material ...
