Sheet metal design for the catering industry: The craftsmanship of sheet metal refers to the ease of parts in punching, bending, and stretching. A good process should ensure that the material consumption is small, the number of processes is small, the mold structure is simple, the service life is high, and the product quality is stable. In general, the most important impact on the workmanship of sheet metal parts is the performance of the material, the geometry of the part, the size and the precision requirements. Saving raw materials means reducing manufacturing costs. Fragmented scraps are often disposed of as waste, so in the design of thin plate components, scraps should be minimized. Punching scrap is minimized to reduce material waste. This is especially effective when blanking large batches of components.
