Some precautions for the processing of small sheet metal parts in Nanjing:

1. Sheet metal small parts processing typically uses materials such as cold-rolled steel (SPCC), hot-rolled steel (SHCC), galvanized steel (SECC, SGCC), copper (CU), brass, bronze, beryllium copper, aluminum plates (6061, 6063, hard aluminum, etc.), aluminum profiles, and stainless steel (mirror finish, brushed finish, matte finish). Nanjing Chengcheng Hardware and Mechanical Factory selects materials based on the specific product function, considering the product's application and cost.

2. Clear division of labor and operational procedures are in place. Different material drop methods are chosen based on the layout diagram and varying batch sizes.

3. Our metal stamping parts are of high quality, not only due to strict production process requirements but also because of independent quality inspections. This includes strictly checking dimensions according to drawings and ensuring the appearance quality. We guarantee product quality.
