一、前言锌铝铜合金是以锌为基体添加一定数量的铜、铝、镁组成的一种新的模具材料。这种模具材料具有较好的机械性能和铸造性能,而且还是一种很好的超塑性材料。有关制造工艺,可充分利用材料的特性,采用浇铸法和热挤压法加工成模具。这种制模方法简化了制模工艺,缩短了制模周期。即使材料反复熔化,其性能也不变。这样就大幅度地降低了生产成本。这种材料可用于制造冲栽模、拉深模、压型模、吹塑模、吸塑模和注塑 First, the preface Zinc aluminum copper alloy is based on zinc as a base to add a certain amount of copper, aluminum, magnesium composition of a new mold material. This mold material has good mechanical properties and casting performance, but also a good superplastic material. The manufacturing process, take full advantage of the characteristics of the material, using casting method and hot extrusion processing into molds. This method of molding simplifies the molding process and shortens the molding cycle. Even if the material is melted repeatedly, its performance does not change. This will significantly reduce the cost of production. This material can be used to make punching dies, drawing dies, compression dies, blow molds, blisters and injection molding
