In recent years, rapid development of precision instruments industry, and precision mold processing these precision instruments are applied to the automobile, electronics, machinery, molds and so the field, which, in terms of medical equipment, automotive, aerospace and other areas of development is relatively strong. However, these precision molds processing technology difficult, high precision process requirements, along with value-added processing chain temperature increased, the profit is high, and so on. Multi-position progressive die production requirements there are some features: coordination difficult, consumes time, long cycle, long life, a higher proportion of size stability, high wear resistance, high strength, high hardness, etc., etc. Three key components
