Continuous Cold Rolled Blades

How to determine the direction of continuous cold-rolled spiral blades: Stand in front of a spiral blade with the opening facing outward. The blade is left-handed if the edges curl to the left, and right-handed if the edges curl to the right.

Product and Technical Features:

1. Helical blades produced through a continuous cold rolling helical blade method, overcoming the drawbacks of traditional helical blade production processes, such as poor accuracy, difficult shaping, high material consumption, and low production efficiency.

2. The blades are smooth and shiny after forming, with high dimensional accuracy and surface hardness.

3. Provide continuous whole blades with spiral lengths as per customer requirements, featuring rigidity, easy welding during use, and convenient assembly for quick installation.

4. Material: Low-carbon steel, stainless steel.

Specs: Thickness 2-6mm, Width 130mm, Inner Diameter 20mm, Outer Diameter 900mm.
