由于模具制造水平的不断提高,如果具备适当的设备和熟练的操作者制造高精度模具就不会有多大困难,但精度一高,模具的结构必然要相应地考虑周密,加工工时也要增加,模具制造时间就长,成本也就提高。特别是近来,为了对付不利于冲压加工的多 Due to the continuous improvement of the mold manufacturing level, it will not be much difficult to manufacture the high-precision molds with appropriate equipment and skilled operators. However, with high precision, the structure of the molds must be appropriately considered and the working hours also increased. Mold manufacturing time is long, the cost will increase. Especially recently, in order to deal with is not conducive to the stamping process and more
