Specifications

1.Good smooth finish
2.Easy to installation
3.After cold rolling, the spirals will be hardened and wear-resistance

Continuous Cold Rolled Screw Flight

 

Method:Continuous Cold Rolled

 

Manufactured by our special technology, our endless cold-rolled spirals have the following features compared to traditional spirals:

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.
