Spiral Blades Cold Rolled Screw Flight Sectional Screw Flight

Spiral Blades Cold Rolled Screw Flight Sectional Screw Flight

The continuous cold rolling blade overcomes the shortcomings of the traditional screw blade production process,such as poor accuracy,difficult formation,large loss and low production efficiency.

After forming,the blade surface is clean,the radial vertical degree is high,the dimension accuracy and the surface hardness are high,can effectively reduce the resistance of the spiral propulsion.Product rigidity,easy to weld and assemble and can be customized according to the length and diameter of customers.
