1, mold manufacturing cost. The production of cold-drawn dies for special-shaped steel pipes requires high-precision processing equipment and technology, and requires high material selection for dies. In the production process, precise CNC machine tools and cutting equipment are needed, which will increase the production cost.

2, mold debugging costs. After the mold is made, it needs to be debugged and optimized to ensure that it meets the product requirements. Due to the complex shape and size requirements of special-shaped steel pipes, the die debugging process is complex and time-consuming, which requires experienced technicians to operate and adjust, and will also increase the cost.
