Extruder screws are one of the most critical components in plastic extrusion machinery, responsible for melting, mixing, and conveying raw polymer materials efficiently through the barrel. These screws, available in 35mm, 45mm, and 55mm diameters, are engineered for optimal performance in blown film plants and plastic processing units. Manufactured using high-grade nitrided alloy steel, they offer superior wear resistance, corrosion protection, and extended operational life, ensuring consistent output quality and improved production efficiency.
