Macross 46 Twin Screw Extruder Screw Elements PE PP PVC ABS Extrusion Parts

Macross 46 Twin Screw Extruder Screw Elements | PE PP PVC ABS Extrusion Parts

Product Overview

High-precision Macross 46 twin screw extruder elements engineered for high-torque co-rotating and counter-rotating twin screw systems. Specifically optimized for plastic extrusion processing including PE, PP, PVC, and ABS pipe, film, profile, and masterbatch compounding lines. Precision-machined with high-grade tool steel and advanced surface alloys to provide high wear resistance, optimal plasticization, and long-lasting production efficiency.

Core Product Advantages

• High Torque & Load Bearing Capacity: Engineed to withstand extreme torque and pressure during heavy-duty compounding of filled polymers and rigid PVC without cracking or spline deformation.

• Superior Self-Wiping Performance: Precision CNC flight profiles ensure complete self-wiping action, preventing material stagnation, carbonization, and cross-contamination during color changes.

• Maximum Wear & Corrosion Resistance: Advanced HIP powder metallurgy and bimetallic options deliver exceptional resistance against highly abrasive additives (glass fiber, CaCO3, TiO2) and corrosive flame retardants.

• Exact Dimensional Interchangeability: Manufactured with tight machining tolerances to guarantee 100% direct drop-in replacement on original Macross 46 extruders with seamless shaft assembly.

Applications & Processing Scenarios

• Pipe Extrusion Lines (PE / PP / PVC): Offers smooth conveyance and uniform heat distribution, preventing thermal degradation during rigid PVC and high-density PE pipe production.

• Film & Sheet Processing (PE / PP / ABS): Equipped with high-dispersion kneading and mixing blocks to eliminate fisheyes, gels, and color streaks in blown and cast films.

• Plastic Compounding & Masterbatch: Provides strong dispersive mixing for high-filler masterbatches (CaCO3, TiO2) and fiber-reinforced plastics.
