Co Rotating Twin Screw Extruder with Nitrided Screw and Barrel for Recycled Plastic Processing

Sichuan Advance Technology Co., Ltd specializes in the research development design and manufacturing of co rotating and counter rotating parallel twin screw extruder complete production lines. We summarize and optimize years of manufacturing experience to develop our exclusive transmission solution and core technology bilateral gear symmetrical driving system.

This core technology endows our extrusion equipment with prominent strengths including high torque high efficiency low energy consumption high cost performance and long service life. Our technical standards keep pace with world top tier extruder manufacturers.

Apart from complete extrusion lines we custom produce interchangeable screw segments compatible with mainstream extruder brands worldwide including Leistritz APV Kobe OMC Buhler KraussMaffei Theysohn Buss Berstorff Toshiba Clextral Labtech USEON Coperion Lantai JSW Keya and Maris.

1. Classified by structural appearance: Closed barrel, fully openable split barrel, vent barrel
2. Classified by inner lining structure: Integrated barrel without liner, barrel equipped with replaceable inner liner

We adopt imported HIP powder high speed steel for barrel production and complete all cylinder processing via precision CNC equipment. The finished barrels achieve the same precision wear resistance and corrosion resistance as original imported parts from top international brands while offering better cost performance than equivalent foreign products.

Ralloy WR13 is a high chromium powder metallurgy tool steel. It contains abundant evenly distributed fine hard carbides which deliver outstanding wear resistance paired with reliable toughness. Its ultra high chromium composition provides stable anti corrosion performance for harsh production environments with corrosive raw materials.

1. Strict raw material inspection: All base materials are sourced from qualified domestic suppliers or professional European twin screw material manufacturers. Every batch undergoes elemental analysis and metallurgical testing to guarantee stable raw material quality.
2. Interchangeable spline standard: Internal splines are inspected with professional spline gauges to guarantee full interchangeability of screw elements and shafts.
3. High precision CNC machining: All core spare parts are processed by CNC machine tools to strictly control dimensional shapes and tolerance ranges.
4. European powder steel forming and heat treatment: We introduce European powder high speed steel processing technology and implement standardized heat treatment procedures. The finished parts match the wear and corrosion resistance level of imported original accessories.
5. Customized technical support team: Our professional engineering team provides fast reverse engineering sample copying customized design and screw element combination process optimization services.
6. Short stable delivery cycle: We reserve complete technical data and dedicated tooling fixtures for mainstream extruder brands to shorten production lead time. Common standard spare parts are kept in sufficient stock. Custom non standard items can be delivered within 45 working days.
7. Full quality traceability system: Modern standardized production management is implemented. All finished products pass full inspection before shipment with 100 percent qualification rate and complete production records for full life cycle traceability.
