China although very already starts to make the mold and the use mold, but long-term has not formed the industry. Straight stabs 20 centuries 80s later periods, the Chinese mold industry only then drives into the development speedway. Recent years, not only the state-owned mold enterprise had the very big development, the three investments enterprise, the villages and towns the mold enterprises development also quite rapid. Cold stamping die has a very important role in modern industry, machinery manufacturing, electronics, appliances and other industries. Cold stamping method can be complex shape, with other processing methods are difficult to process work pieces, such as the shell parts, etc. Cold stamping molds to ensure dimensional accuracy, therefore, dimensional stability, interchangeability. Multi-position into modules are o-level into mode in the developed on the basis of precision, high efficiency, high life-span advanced mold. Multi-position into the mold in different location can continuously complete complex components cutting, bending, deep drawing, the hole flanging
