1. The material of the roller body is generally selected from high-quality seamless steel tubes (special materials can be customized according to user needs). After boring and grinding the inner hole, the thickness of the tube wall is uniform, and then it is made by welding, stress relief treatment, turning, grinding, and finishing;
2. Correct the static balance and dynamic balance treatment; the coaxiality of the finished roller ≤0.02mm;
3. According to the pattern, different processing techniques are adopted to achieve a clear pattern, exquisite pattern, rich levels and precise size of the extruded product.
4. The final surface is plated with hard chrome or other treatments, and the hardness can reach HRC58-62.
