Factory Direct 96/96 W6Mo5Cr4V2 Screw Elements for German Extruders
Wear-Resistant 6542 M2 HSS Screw Components for German Twin-Screw Lines
Product Overview
High-throughput plastic compounding lines running German first-line brand twin-screw extruders demand strict machining tolerances and consistent metallurgy. Rapid wear or poor spline fit can cause pressure drops, screw-shaft vibration, and unexpected factory downtime.
CONLIN manufactures 96/96 size twin-screw extruder elements using premium W6Mo5Cr4V2 (6542) high-speed steel. Built specifically as direct replacements for major German extruder platforms, these 96 mm outer-diameter elements undergo precision thread grinding and computerized vacuum heat treatment. The result is a component that balances surface hardness with core toughness to handle high mechanical stress and abrasive resin processing.

Key Advantages
Direct Drop-in Replacement: Precision hobbed spline bore guarantees exact fit onto original German extruder shafts without extra shop-floor modification.
Premium M2 Tool Steel: W6Mo5Cr4V2 alloy provides balanced wear resistance and high structural toughness under heavy mechanical loads.
Computer-Controlled Vacuum Hardening: Uniform 60–64 HRC hardness throughout the element prevents premature flight breakdown and cracking.
Reduced Friction & Stagnation: CNC profile-ground surfaces minimize melt friction, lower heat buildup, and streamline color changes.
Product Applications
Engineering Plastics Compounding: Compounding PA6, PA66, PBT, PET, and POM with moderate glass-fiber loading.
Masterbatch Production: Processing high-pigment masterbatch, calcium carbonate fillers, and additive concentrates.
Polyolefin Processing: Compounding high-density polyethylene (HDPE), polypropylene (PP), and TPO resins.

FAQ
Q1: How does domestic W6Mo5Cr4V2 (6542) compare to imported AISI M2 or DIN 1.3343 steel?
A: W6Mo5Cr4V2 (6542) shares identical chemical composition and mechanical properties with AISI M2 and DIN 1.3343. We source alloy billets from certified steel mills and apply computerized vacuum heat treatment to achieve uniform carbide distribution, ensuring wear performance equal to European-sourced raw materials.
Q2: Will your 96/96 elements match the spline clearance of original German extruder shafts?
A: Yes. We process the internal bore using precision spline hobbing tools built to DIN 5480 involute spline standards. The pitch diameter, pressure angle, and backlash clearances match German OEM shaft dimensions, ensuring smooth slide-on fitting without shaft binding.
Q3: Can 6542 (M2) steel elements withstand high concentrations of glass fiber?
A: W6Mo5Cr4V2 handles low to moderate filler contents (up to 20%–25% glass fiber or CaCO3) effectively. For extreme abrasive environments containing 30% to 50% glass fiber, we recommend upgrading to powder metallurgy (PM) HIP sintered alloys (such as WR13 or CPM 10V) for extended wear life.
Q4: How do you verify dimensional accuracy before shipping 96/96 replacement elements?
A: Each 96/96 element undergoes inspection on Coordinate Measuring Machines (CMM) and optical profile projectors. We check outer diameter tolerances, screw flight pitch geometry, spline backlash, and surface hardness (60–64 HRC) before applying anti-rust coating and export packaging.
