The structure of the blanking part is technological. The shape of the blanking part shall be as simple as possible, symmetrical and avoid the curve of complex shape. If permitted, the blanking part shall be designed into the shape of less and no waste layout to reduce waste. Both ends of the rectangular hole should be connected by circular arc to facilitate die processing. Sharp corners shall be avoided at the connection of straight lines or curves of blanking parts, and sharp corners are strictly prohibited. In addition to less or no waste layout or the use of inlaid die structure, there should be appropriate rounded corners to facilitate die manufacturing and improve die life.

Automotive sheet metal parts
