Common problems and solutions for hardware stamping parts in Shenzhen:

1. When designing the structural appearance of hardware stamping parts, a simple and reasonable appearance and its combination should be adopted, while also minimizing the number of processed surfaces and processing area as much as possible.

2. Choosing a reasonable method for blank preparation in mechanical manufacturing can directly apply materials such as profiles, casting, forging, stamping, and welding. The selection of blanks is related to detailed consumption technical conditions, and generally depends on consumption batch size, data performance, and processing possibilities.

3. The requirements for the formability of metal stamping parts require good plasticity, low yield strength ratio, large plate thickness directionality coefficient, small plate plane directionality coefficient, and low ratio of yield strength to elastic modulus in order to facilitate the improvement of stamping deformation and product quality. The separation process does not require data with good plasticity, but data with a certain degree of plasticity.

4. Proper manufacturing accuracy and surface roughness according to regulations. The cost of metal stamping parts will increase with the progress of accuracy, especially in cases of high accuracy, where this increase is extremely significant. Therefore, high accuracy should not be pursued without sufficient evidence. Similarly, the surface roughness of metal stamping parts should also be determined according to the practical needs of the matching surface.
