In plastic processing, the screw and barrel assembly is more than just a component—it is the engine that drives the entire production process. When this critical part begins to wear or fails to perform as expected, the consequences ripple across the entire operation: inconsistent melt quality, reduced throughput, increased scrap rates, and unplanned downtime that can cost thousands of dollars per hour. For plant owners, procurement managers, and engineers responsible for maintaining production efficiency, understanding the nuances of screw technology is not optional—it is essential. Shreeji Corporation, headquartered in Ahmedabad, Gujarat, has been delivering precision-engineered solutions to the plastics industry since 2004. With complete in-house capabilities spanning product design, manufacturing, machining, quality control, testing, and warehousing, the company has established itself as a trusted partner for businesses across India and international markets, including the Gulf co...

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 ...
