Continuous cold-rolled screw flights are seamless, continuous integral spiral blades made through cold rolling forming technology. They are the core components of spiral conveying equipment. Compared with traditional welded blades, they have the characteristics of high dimensional accuracy, smooth surface, uniform pitch, good strength and wear resistance, low conveying resistance, high production efficiency, and low cost. Different specifications of outer diameter, inner diameter, pitch, and length can be customized according to demand.

Continuous cold-rolled screw flights overcome the previous production methods of single piece cutting, stretching, welding, and polishing. The blade surface is smoother, the size is more precise, the overall rigidity is strong, and installation is convenient and efficient .

The thickness of the outer edge of the blade is about half of the thickness of the root, and after rolling, the hardness of the outer edge is increased by more than twice, which improves the wear resistance of the blade.

We can customize production according to customer requirements.

Continuous cold-rolled screw flights are widely used in the transportation of powdered, granular, and small conventional materials in industries such as building materials, chemical, grain, coal, metallurgy, and mining; At the same time, it is suitable for the transportation of viscous/irregular materials such as sludge and garbage in the field of environmental protection treatment, the transportation of grain, feed, and organic fertilizer raw materials in the agricultural field, as well as the transportation of materials that require anti-corrosion and hygiene in food, pharmaceutical, and light industrial manufacturing.
