家用电器的塑制品装饰件要求光洁度高,几何形状复杂,注塑用的凹模采用的机加工、电火花加工都不能满足要求。近年来,国外已普遍使用电铸法来制作凹模。采用这种方法的优点是: 1.可制造外形复杂,花纹细致、深孔和配合精度很高的凹型模; 2.光洁度高。高光洁度的模芯可电铸成高光洁度的凹模; Household appliances, plastic products, decorative pieces require high finish, complex geometry, injection mold used in machining, EDM can not meet the requirements. In recent years, foreign countries have generally used electroforming method to produce concave mold. Advantages of using this method are: 1. Can produce complex shape, delicate patterns, deep holes and with high precision concave die; 2. High finish. High-finish mold core can be electroformed into a high-finish die;
