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.

Material:Carbon Steel, Low Alloy Steel, Wear Resistant Steel, Stainless Steel.
It solved the problem that the continuous cold rolling is difficult to control in large diameter, large thickness and special size and difficult to forming in High carbon steel, alloy steel, stainless steel materials.
It is single pitch shape, the inner and outer thickness are the same. The outer diameter, inner diameter and pitch can be exactly produced according to customer’s need.
