Our modular building-block type twin screw elements include full series of standardized parts such as conveying segments, forward and reverse thread segments, various angle kneading blocks and special mixing blocks. All components adopt unified standard spline interface design, with strong universality and interchangeability, and customers can freely combine and assemble different screw elements according to different raw material characteristics, production processes and output requirements. The modular design greatly improves the flexibility of the extrusion process, which is not only suitable for mass industrial production of plastic modification, granulation and recycling, but also perfectly adapted for laboratory small-batch trial production, new material research and formula testing. Each screw element is processed with high precision, with smooth surface, small operation resistance, short material residence time and excellent self-cleaning performance, effectively avoiding material residual deterioration and cross-contamination. Made of high-quality wear-resistant alloy and treated with professional heat treatment, the products have stable mechanical properties and long service life. We provide professional screw configuration design services, complete product assembly manuals and detailed process matching guidance. In after-sales service, we support global fast delivery, standardized export packaging, 12-month full warranty, regular customer return visits, remote operation guidance and lifelong technical consulting services.
