Counter Rotating Twin Screw

Our Counter Rotating Conical Twin Screw System is engineered to deliver unmatched precision in extrusion processes requiring superior pumping efficiency and material fidelity. Unlike conventional designs, the counter-rotating action creates a positive displacement mechanism, making it the definitive solution for demanding applications with high-viscosity or thermally sensitive compounds, such as specialized PVC and high-fill materials.

This system integrates the volumetric compression of a conical geometry with the controlled, positive displacement of counter-rotating screws. The intermeshing screws form sealed "C"-shaped chambers that transport material with exceptional precision from feed to discharge. This fundamental design is optimized for formulations where precise meterings, minimal shear history, and efficient venting are critical to the final product's integrity.

The conical taper naturally enhances compaction and builds extremely stable die pressure, which is essential for producing extrudates with impeccable dimensional accuracy and surface quality. For processing challenging materials, this configuration provides a decisive advantage: it inherently minimizes axial pressure fluctuations, thereby ensuring consistent output and reducing product variance. The mechanical action is inherently self-cleaning, promoting material purity during transitions and reducing downtime.

Durability is engineered into every component. The screws and barrels are manufactured from advanced, wear-resistant alloys. For the most abrasive formulations involving high filler loads, we offer bimetallic barrel liners and specially hardened screw surfaces to extend operational life significantly. The system's architecture also allows for versatile customization, including tailored screw profiles, multiple venting stages, and specific L/D ratios, to align perfectly with your unique process rheology and end-product requirements.

Our conical twin screw and barrel system is the core component for high-efficiency PVC extrusion. It is expertly engineered for producing high-precision profiles, pipes, sheets, and decorative moldings, making it the ideal solution for the construction, home furnishing, and industrial sectors.

Its outstanding processing stability ensures consistent quality even for complex cross-section products, providing a durable, reliable, and efficient foundation for your production line.

Quality is embedded in our process and promised in every product. Our ISO 9001:2015 certified quality management system ensures traceability and consistency from material selection to final inspection.

We implement strict testing protocols at every critical manufacturing stage, using advanced equipment to verify dimensions, hardness, nitriding depth, and surface finish. This guarantees each screw and barrel not only meets but often exceeds industry standards for precision, durability, and performance.

To us, quality is a commitment to your success. It means delivering components that ensure long-lasting, reliable operation in your most demanding environments, minimizing downtime and maximizing your return on investment.
