Examples of "joint" die-casting processing [Prototyping and mass production available from 1 piece!]
Compared to pressed products, the precision of distortion and other factors after molding 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. The initial investment (such as mold costs) for press molds requires a concave-convex type, while hemming only requires a basic 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 rotated and drawn, the stress in the rolling direction of the material can be reduced, resulting in higher precision in post-forming distortions compared to pressed products.

basic information
【Processing Steps】 ■1. Cut the material sheet into circles (slitting) ■2. Fix the material in the spatula drawing mold (on, men type) and rotate the mold and material ■3. Press a jig (roller) against the rotating material and perform the spatula pressing process ■4. After completing the same process, carry out processes such as cutting, curling, and hemming *For more details, please feel free to contact us.
