Stampings primarily sheet metal or non-metallic, with the pressure of the press, by stamping die stamping forming. It has the following features:

(1) Stamping bright surface, no spots, no scars, no scratches and no surface cracks;

(2) Stamping high dimensional accuracy, the size of the module with uniform, better compatibility;

(3) subject to uniform intensity, no taste of bias;

(4) a uniform stretch rate;

(5) low yield ratio;

(6) hardening low;

(7) does not require further machining and assembly to meet the general requirements;

(8) stampings are not under the premise of material consumption broken by oppression rushed to come, its parts light weight, stiffness, and the sheet metal by plastic deformation of metals to improve the internal layout of the structure lost so stampings strength and progress;

(9) stamping parts stamping process, because the inner material is not crushed, it has a good heart quality. Bright appearance, which is the heart painting, plating, phosphate, and also supply the arbitrary disposal of heart conditions.
