Technical Specifications

Company Strength

1) 20+ Years of Material Expertise: We don't just machine parts; we understand the metallurgy behind alloy materials. We know exactly which steel grade fits your specific calcium powder proportion (e.g., 35% CaCO3).

2) Global OEM Compatibility: Our database covers almost all major international brands. You only need to provide the model or a simple drawing.

3) Strict Quality Gate: Every shipment includes a Material Certificate and a Dimensional Inspection Report. We offer video outgoing inspections for your peace of mind.

4) Cost-Effective Logistics: Fast turnaround (30–60days) with reliable international shipping, ensuring your production line never stays idle.

Target Applications & Industries

Our screw elements are the "workhorse" for challenging compounding tasks:

WPC (Wood Plastic Composite): Handling high-abrasion wood fiber loads.

PVC Compounding: Resistant to the corrosive nature of rigid and soft PVC.

Masterbatch Production: High-dispersion elements for carbon black and TiO2.

Engineering Plastics: Processing PA6, PA66 + Glass Fiber (up to 50%+).

Biodegradable Plastics: Precise temperature control for PLA/PBAT/Starch blends.

FAQ

Q1: How do I know if these elements will fit my specific extruder brand?

A: We manufacture elements that are 100% interchangeable with major brands like Coperion, Leistritz, and others. We verify fitment through standard serial numbers or custom drawings.

Q2: My process uses 35%+ Calcium Powder. How will your elements hold up?

A: For high-filler (CaCO3) applications like PVC/WPC, we recommend our specialized High-Vanadium Alloy or Bimetallic coatings, which specifically prevent abrasive "scouring" of the screw flights.

Q3: Can you produce custom kneading blocks based on our formula?

A: Yes. We can customize the L/D ratio, stagger angles, and disk thickness to improve mixing efficiency for specialized engineering plastics.

Q4: Do you offer samples for testing?

A: We encourage trial orders. Testing a set of kneading blocks in your most high-wear zone is the best way to prove our durability.
