Stainless Steel Screw Barrel

The Stainless Steel Screw Barrel is primarily chosen for injection molding applications involving highly corrosive polymers, such as PVC, fluoropolymers, or flame-retardant materials, because of its superior corrosion resistance compared to standard nitrided steel, which significantly extends the service life and prevents chemical degradation of the melt flow channel; typically constructed from high-grade stainless alloys (like SS304 or SS420), this assembly, which still features the essential feed, compression, and metering screw geometry, ensures a high-quality, uncontaminated melt and maintains dimensional accuracy under challenging chemical environments, reducing costly downtime and product defects.
