Moscow Screw Barrel

A Moscow Screw Barrel refers to a high-quality component typically manufactured using EN-41B steel with Mosco grade material, which is specially heat-treated via a process like gas nitriding to achieve superior surface hardness (often 65-70 HRC) and excellent resistance against wear, corrosion, and abrasion. This combination of material and treatment is favored for heavy-duty applications in injection moulding and extrusion machinery, especially when processing abrasive materials like glass-filled polymers or corrosive resins. The precision-engineered screw works within the robust barrel to ensure optimal plasticization, mixing, and homogenization of the polymer melt, leading to consistent product quality and extended service life.
