Continuous Cold Rolled Screw Flight/Helical Screw Conveyor Flight

Continua laminados en frio tornillo de vuelo / helicoidal tornillo transportador de vuelo

Our endless cold rolled screw flight overcomes the shortcoming of poor precision, difficult forming, low using rate of materials and low working efficiency which are inherent in the traditional manufacturing method of flight brought by single blade cutting, drawing and welding. After the cold rolled, the surface becomes smooth, the precision is high, whole rigidity is good, the surface harness is improved. The length of the flight can be made according to the customers' demand, which is much convenient for the subsequent handling of the screw conveyor manufacturing.

Our main products for export as follows:
Carbon Steel Spirals for Screw Conveyors
Carbon Steel Spirals for Combine Harvester
Manufactured by our special technology, our endless cold-rolled spirals have the following features compared to traditional spirals. 90% of the products exported to America, Australia and Europe.

1. Good smooth finish, uniform shape and high precision. It's conducive to material conveying, reduce the product damage, and to increase the transporting efficiency.
2. Easy to installation, improve the work efficiency and reduce the production cos.
3. Under the physical and chemical surface treatment, the spirals enhances the anti-rust property and improves the appearance of screw conveyors.
4. After cold rolling, the spirals will be hardened, which will enhance greatly the rigidity and the wear-resistance, say by one time. The HB value is 240.
