1. * * Dimensional accuracy * *: Dimensional accuracy directly affects whether the parts can meet assembly requirements. By designing molds reasonably and optimizing processing parameters, the dimensional tolerances of metal stamping parts can be effectively controlled.
2. * * Surface Quality * *: Good surface quality not only affects aesthetics, but also relates to the functional performance of components. Avoiding defects such as scratches and dents and ensuring a smooth and flawless surface of the product is one of the essential standards that must be met.
3. Consistency of Material Thickness: During the tensile deformation process, it is necessary to ensure that the thickness of each part of the material is evenly distributed to prevent the problem of local thinning leading to a decrease in strength.
4. Shape complexity and stability: With the development and progress of industrial technology, the market's requirements for the shape of metal stamping parts are becoming increasingly diverse and complex, which requires production processes to have high stability and flexibility to adapt to different production tasks.
5. * * Mechanical performance indicators * *: Various mechanical properties, including tensile strength, yield limit, and other physical properties, are also important criteria for measuring the quality of metal stamping parts.

In short, only by comprehensively considering the above factors and strictly controlling the quality standards of each process can we produce high-quality metal stamping parts that meet customer needs. At the same time, enterprises should continuously strengthen their investment in technology research and development, and promote the industry to move towards higher levels.
