Product and technical features:

1. The spiral blade produced by the continuous cold rolling method overcomes the shortcomings of the traditional spiral blade production process, such as poor precision, difficult forming, high material consumption, and low production efficiency.

2. After the blade is formed, the surface is smooth and clean, with high dimensional accuracy and surface hardness

3. Provide continuous integral blades according to the spiral length required by customers, with good rigidity, welding during use, convenient and fast assembly

4. Material: low carbon steel, stainless steel
