(1) because when stamping die to ensure the stamping precision of size and shape, and generally does not destroy the surface of the stamping parts quality, and the life of the mould are long, so the quality of stamping not disorderly, good compatibility, has the characteristics of "the same".

(2) the stamping generally does not have the raw material, the material is consumed less, and the other heating equipment is not needed, but is a kind of province material, the energy-saving processing method, the stamping parts of the lower money。

(3) stamping for processing the size range is larger, more complex shape parts, such as small to watch the stopwatch, big to auto longeron, cover parts, etc., and stamping material hardening effect of cold deformation, the strength and stiffness of stamping was high.
