Product Description
As the "heart" of plastic extruders, our precision-machined extruder screws are engineered to deliver exceptional plasticizing performance and long-lasting durability. Adopting alloy materials and CNC precision manufacturing, these screws are compatible with PP, PE, PVC, PA, PC, ABS and other thermoplastic materials, effectively solving common production pain points such as uneven plasticization, frequent wear, and unstable output.
Our extruder screws are widely used in global plastic processing industries:
• Pipe/Profile Extrusion: PVC drain pipes, PE gas pipes (ensures uniform wall thickness).
• Film/Sheet Production: PP packing belts, PET sheets (high plasticization, no crystal points).
• Pelletizing Lines: Recycled material pelletizing, modified material pelletizing (wear-resistant for harsh conditions).
• Engineering Plastics Processing: PA (nylon), PC (polycarbonate), ABS processing (stable performance at high temperature).
1. Superior Material & Wear Resistance
• Base Material: 38CrMoAlA alloy steel, featuring high tensile strength and impact resistance.
• Surface Treatment: Nitriding process creates a 0.15-0.3mm hard layer with surface hardness up to HV900+, 2x more wear-resistant than ordinary screws.
• Corrosion Resistance: Withstands high-temperature (≤300ºC) and chemical corrosion from plastic additives, suitable for high-filler material processing (e.g., calcium carbonate filling) .
2. Scientific Structure for Stable Output
Adopting three-section optimized design to ensure efficient material processing:
• Feeding Section: Equal pitch + deep screw groove design prevents "bridging" and blockage, increasing material conveying efficiency by 20%.
• Compression Section: Gradually reduced groove depth compacts and preheats materials, achieving smooth solid-to-melt transition.
• Metering Section: Equal-depth groove ensures molten material output with stable pressure and uniform flow, reducing product defects by over 90%.
3. Full Customization for Diverse Needs
Tailor-made solutions based on your equipment and processing requirements:
• Parameter Customization: Screw diameter, L/D ratio, compression ratio all adjustable.
• Material Adaptation: High compression ratio for crystalline plastics (PA, PP); low compression ratio for amorphous plastics (PVC, PC).
4. Precision Manufacturing
• Processing Equipment: CNC precision lathe, grinding machine, and 3D measuring instrument ensure dimensional accuracy.
• Quality Inspection: 100% dynamic balance test and pressure resistance test before delivery.
