快速经济模具,是指比传统的机加工方法成形的模具制造周期短、成本低、综合经济效益较好的一类模具。在模具的精度和寿命方面,能满足生产要求。按制模工艺可把这类模具分为五类:①铸造成型模(包括低熔点合金模、锌基合金模、陶瓷型精铸模、树脂型复合模等);②喷涂成形模;③电化 Rapid economic mold, is more than the traditional machining methods of mold forming cycle is short, low cost, better overall economic efficiency of a class mold. In the mold of precision and longevity, to meet the production requirements. According to the molding process can be divided into five categories of such molds: ① casting mold (including low melting point alloy die, zinc-based alloy die, ceramic casting mold, resin-based composite die, etc.); ② spray forming die;
