Parallel Twin Screw & Barrel

1.Material: 38CrMoAIA

Nitriding treatment, Surface hardness: HV≥900

Nitriding depth: 0.5-0.8mm

2.Base material: 38 CrMoAIA A, Special alloy is welded on the flight of screw, prolong life of screw.

3.Easy wearing parts of barrel made from anti-wear alloy can be improved abrasion performance.

The production of high profile PVC, PVC pipe with large bore, and WPC extrusion requirments of research and development, with the small shear rate, soft compressed, and the material is resist to compose, the good plasticzing, high output, wide application range, high reliability.

Confirm the material being processed, HRC, value, quantity, according to drawings and samples requires grinding forming angle and tolerance...... Mass production is now only, can completely replace the international first-class products, is highly cost-effective.

With the advanced integrated production system, and all kinds of precision technology production and processing capacity, it can realize high efficiency, and low cost application.

From the six axis, seven axis CNC machining high-grade products to the three shaft, four axis production (B) middle grade products, different levels of quality and price...Professional alternative to first-class industrial products, special, non-standard, special-shaped, new products in large quantities, the high cost of research and development, production and processing, according to drawings and samples to improve the design, can greatly reduce the comprehensive cost.

Please provide samples or requirments about dimensions and tolerances of, semi-finished and finished products, the equipment, equipment value RMB ( to judge its rigidity and jumping), the monthly consumption quantity, the current screw u are using, HRC . and so on.
