Precision casting with a small investment scale, large production capacity, low production cost, the advantages of complex product process simplification, investment, fast effect. Thus in competition with the rest of the process and the means of production in a favorable position, a bright future.Hand watchcase production methods have plastic injection forming, zinc, aluminum alloy die-casting forming, sheet metal stamping forging forming, stamping forming is divided into cold forging into, temperature, pressure and hot pressing.With revestment precision casting method for mass production hand watchcase manufacturer is very few, so hand watchcase main methods of production or in the sheet metal stamping as the main production methods.But stamping method cannot production of complex shape and shell body have special requirements (such as: shell body is square and complex pattern of blind holes, shell, shell body with concave and convex word, etc.) hand watch case.Moudle for austenitic stainless steel produced by the method of precision casting, broke through the original sheet stamping method is unable to make field, precision casting also marks the mass production by revestment precision casting method hand watchcase technology is gaining recognition, fill the watchmaking and precision casting industry a blank.In shape and appearance to make hand case had the new breakthrough, make revestment precision casting on the dimensional accuracy requirements have a higher pursuit.
