JSW Enhances TEX 65 Extrusion with Precision Screw Engineering

When extrusion lines experience production fluctuations, inconsistent plasticization, or frequent maintenance shutdowns, the root cause often lies not with the main machine, but with those seemingly insignificant screw elements. As the "heart" of twin-screw extruders, the geometric precision and material properties of screw elements directly determine material conveying, shearing, mixing, and plasticization effects.

Core Specifications and Manufacturing Process

For JSW TEX 65 extruders, screw elements are precision-engineered with an outer diameter strictly controlled at 68.25 mm. To ensure stability under demanding conditions, all components undergo vacuum quenching treatment, maintaining hardness within HRC 58-62. This process delivers exceptional surface hardness while preserving internal toughness, effectively preventing brittle fractures during high-torque operation. The production system complies with ISO 9001:2015 quality standards, ensuring high interchangeability and consistency across all delivered products.

Industry Adaptability and Compatibility

These screw elements demonstrate remarkable versatility across multiple industries including plastic modification, wood-plastic composites (WPC), food processing, and powder coating production. Beyond JSW TEX 65 compatibility, the solution supports customization for major global brands including Coperion, Berstorff, KraussMaffei, Buhler, Toshiba, Clextral, Leistritz, Maris, Theysohn, Buss, APV, KOBE, OMC, Labtech, USEON, Lantai, and Keya.

Modular Design for Precision Processing

The comprehensive range of screw element types addresses diverse material processing requirements:

• Conveying Screw Elements: Ensure stable, efficient forward material transport
• Mixing & Kneading Blocks: Facilitate effective dispersion and distributive mixing through variable lobe counts (1-lobe, 2-lobe) and staggered angles
• Transition Elements: Provide smooth connections between functional zones to minimize pressure fluctuations
• Special Function Elements: Including deep-channel conveying elements and side-feeding components for complex formulation processing

Material Science for Extreme Conditions

Tailored material solutions address specific production challenges:

• High-Wear Applications: W6Mo5Cr4V2 tool steel or PM HIP materials (WR5, WR13, WR14, CPM10V, CPM9V) combat abrasion from highly filled materials
• Corrosive Environments: Nitrided steel 38CrMoAl or corrosion-resistant PM HIP materials (WR13, WR14, CPM10V, CPM9V) plus specialty stainless steels (316L, C276) handle acidic or corrosive materials
• Combined Wear-Corrosion Challenges: PM HIP high-performance alloys maintain hardness while delivering exceptional chemical resistance

Flexible Manufacturing Capabilities

As a leading Chinese manufacturer of twin-screw extruder components, the production system covers screw and kneading block diameters from 15.6 mm to 350 mm and beyond. Optimized for "multi-variety, small-batch" flexible manufacturing, the operation delivers both standard replacement parts and customized solutions for specialized processes with rapid turnaround times.
