Overview
Our Screw Elements are precision-engineered components designed for high-performance extrusion and processing applications. Available in a wide diameter range from φ11 mm to φ350 mm, these elements are compatible with leading extrusion equipment, ensuring efficient material conveying, mixing, and processing across diverse industrial applications.
Compatible Brands
These screw elements are suitable for top-tier extruder brands, including Coperion, Leistritz, KraussMaffei, JSW, Toshiba, Baker Perkins, SM Platek, Wenger, Clextral, Bühler, BUSS, and more.
Materials & Construction
Manufactured from premium materials such as tool steel, HIP, stainless steel, nickel-based alloys, cobalt-based alloys, and other specialized metals. Advanced surface treatments, such as nitriding or hard chrome plating, enhance wear resistance, corrosion resistance, and durability, ensuring long service life even under demanding processing conditions.
Key Product Types
Conveying Elements
Our screw elements include wide single-flight, double & triple-flight types. Single-flight boosts material & efficiency, self-cleaning, suitable for low-density powders. Double-flight aids feeding & exhaust with large lead, optimizes residence & melting with small lead. Triple-flight offers high shear, flexible temp/pressure control, effective degassing. Choose us for enhanced extruder performance.
Kneading Blocks
Kneading blocks are mixer enhancers in extruders. 30° excels in conveying, ideal for first kneading; 60° for superior mixing; 45° often used in series. Backward block reverses flow, boosts backpressure for mixing. 90° applies high energy, restricts flow, ensures melting, increasing screw fill.
Mixing Elements
Mixing Elements are designed for efficient mixing. SME elements utilize multiple backflow grooves to enhance dispersion with low energy consumption. TME toothed disk elements feature forward and reverse teeth pairing for good dispersion with moderate energy consumption. ZME toothed elements, with staggered angle cutting, deliver superior dispersion but consume slightly more energy.
Applications
Plastic Processing: Extrusion granulation, pipes, films, and sheets, with uniform additive dispersion.
Filled & Modified Plastics: Incorporation of inorganic fillers such as calcium carbonate and talc for improved rigidity and dimensional stability.
Heat-Sensitive Materials: Gentle mixing minimizes thermal degradation, suitable for PVC, PET, and engineering plastics.
Industrial Chemical & Energy Facilities: Enhances processing efficiency in oil refining, natural gas, and chemical plant extrusions.
