Examples of "pipe" die stamping processing [Prototype and mass production available from 1 piece!]

Compared to pressed products, the precision of post-forming distortion and other factors is higher in draw forming processing. It requires low initial investment and is suitable for small-batch production of various types. [Case study materials available]

Hemming is a method of shaping metal sheets by rotating them to form a rotational body shape. While the initial investment (such as mold costs) for press molds requires a concave-convex type, hemming primarily requires only a convex type. The cost of a hemming mold starts from 20,000 yen, while a press mold starts from 250,000 yen (for simple shapes), allowing for a very low initial investment, making it suitable for small-batch production of various types. Additionally, because the material is shaped by rotation, the stress in the rolling direction of the material can be reduced, resulting in higher precision in post-forming distortion compared to pressed products. [Example of Hemming Processing] Copper, thickness 2.0 mm (maximum outer diameter Φ70, total length 245) The right side of the pipe is a closed tube, and the left side has a reduction rate of 28%.
