1 Key points of overall design of sheet metal parts

1)Avoid external and internal sharp corners  

Safety considerations: sharp corners on the outside of sheet metal can easily cause operators or users to cut their fingers.

Stamping mold factor: The sharp corners of sheet metal correspond to sharp corners on the mold. The sharp corners on the concave die of the mold are difficult to process, and at the same time, they are extremely easy to crack during heat treatment, and the sharp corners are easy to collapse and wear out too quickly during punching, resulting in lower die life.

2)Avoid overly long cantilevers and narrow slots

3)Size of sheet metal punching holes

4) Pitch and hole edge distance of sheet metal punching

The small size of the corresponding cam die on the stamping mold, low strength, short die life, and the excessively long cantilever may also cause the waste of sheet metal materials.

5) Avoid holes too close to sheet metal bending edges or forming features

2 Sheet metal bending design

1)Height of bending

If the height of sheet metal bending is too low, the bending area will be easily distorted and deformed, and it is not easy to get the ideal part shape and the ideal dimensional accuracy.(Depends on the thickness of Material)
