92 Nickel Alloy Screw Elements for WPC Extruders | Factory Custom
Wear & Corrosion Resistant 92 Nickel Screw Elements | Direct Factory
Product Overview
Wood-Plastic Composites (WPC) contain sharp natural wood flour, plant fibers, and mineral fillers. During high-temperature compounding, these materials create heavy surface friction and release acidic gases. Standard tool steel screws wear down quickly under these conditions. As screw clearances expand, extrusion pressure drops, output decreases, and melted plastic scorches.
Our factory builds 92 Nickel Alloy Screw Elements specifically to solve these wear and corrosion problems in Φ92mm twin-screw extruders and pelletizers. We combine nickel, chromium, and molybdenum in a dense alloy structure. This material delivers high surface hardness (58–64 HRC) and stays stable up to 450°C.
We handle all manufacturing inside our own facility. Whether you need conveying segments, kneading blocks, or mixing elements, we make exact drop-in replacements. If you run custom machine sizes or non-standard spline shafts, send us your CAD drawings or worn physical samples. We scan, reverse-engineer, and machine the exact screw parts you need to restore your production lines.

Key Technical Features
-
Factory Custom Manufacturing: We machine custom flight pitches, angles, and splines directly from your sample or drawing.
-
High Wear Resistance: The hard nickel matrix prevents surface scratches from rough wood powders.
-
Chemical Acid Protection: It neutralizes corrosive vapors from heated wood fiber without rusting.
-
CNC Precision Fit: Strict size tolerances eliminate gap leakage, keep melt pressure steady, and lower energy costs.
Product Applications
Our screw elements run reliably across demanding plastic compounding lines:
-
WPC Pelletizing Lines: PE, PP, or PVC formulations mixed with 50% to 70% wood flour.
-
Highly Filled Plastics: Compounding plastics loaded with glass fibers, calcium carbonate, or flame retardants.
-
WPC Profile Extrusion: Direct extrusion of outdoor deckings, fencing, and building boards.
-
Brand Compatibility: Direct replacements for Coperion, Berstorff, Leistritz, Theysohn, and Asian extruders.
Packaging & Global Shipping
-
Anti-Rust Coating: We apply protective oil and seal parts inside VCI anti-corrosion bags.
-
Foam Protection: Custom foam slots keep screw segments separated during transit.
-
Solid Wooden Crates: Fumigation-free export plywood boxes protect sea and air shipments.
Frequently Asked Questions (FAQ)
Q1: Can you copy our screw elements from a worn sample?
Answer: Yes. Send us your worn sample. We use 3D laser scanners to measure dimensions and machine brand-new parts.
Q2: Is 92 Nickel Alloy better than tool steel for WPC extrusion?
Answer: Yes. Tool steel wears down and rusts when exposed to acidic wood gases. 92 Nickel Alloy resists both physical wear and chemical corrosion.
Q3: What is your average production lead time?
Answer: We ship standard elements in 7 to 10 days. Custom elements built from drawings take about 15 days.
Q4: How do precision screw elements improve pellet quality?
Answer: Tight tolerances close the gap between screws and barrel walls. This stops material backflow, prevents overheating, and makes uniform pellets.
Q5: Do you supply other twin-screw machine parts?
Answer: Yes. We also manufacture high-torque shafts, bimetallic barrels, kneading blocks, and full screw assemblies.
