Ensure Equipment Safety and Stability
Incompatible screw elements can cause poor fit between the screw and barrel, leading to jamming, vibration, or even barrel wear, which impacts product quality and equipment lifespan.
Optimize Production Efficiency
Compatible screw elements ensure smooth material flow in the extruder, improving output and mixing uniformity.
Extend Service Life
Proper screw elements balance load and reduce wear, allowing screws and barrels to operate reliably over long periods.
Check Model and Specifications
Provide the screw element’s model, diameter, length, pitch, and thread type and compare with the equipment manual to ensure a perfect match.
Material Selection
Different processes require wear-resistant or corrosion-resistant materials. Common materials include tool steel, nitriding steel 38CrMoAlA, PM-HIP, nickel-based alloys, etc. Material must match the original equipment design to maintain longevity.
Precision Inspection
Screw element precision directly affects extruder performance. Key indicators to check include screw tolerance, surface roughness, and hardness.
Consult Professional Suppliers
Professional manufacturers like ZHITIAN or Coperion OEM can provide custom screw elements based on your machine model, ensuring compatibility and offering inspection reports and after-sales support.
When selecting or replacing twin-screw extruder screw elements, compatibility is the top priority. By verifying specifications, choosing suitable materials, ensuring machining precision, and working with professional suppliers, you can significantly improve production efficiency, extend equipment life, and maintain stable product quality.
