实际生产中,各种钣金零件的质量要求不同,生产批量也不同。为了取得最大的技术—经济效益,有时就必须为满足某些方面的要求,而舍弃其他方面的要求。如,为提高产品的质量,必须采用高精度、结构复杂的模具,这就会提高模具成本并延长生产准备周期;而在需求量不大或对产品的质量要求不高时,就应该放弃对产品的高质量要求,尽量缩短生产周期、降低制模成本,这时就应该采用各种简单的经济模具结构形式。
In actual production, all kinds of sheet metal parts of different quality requirements, production volume is also different. In order to achieve the greatest technical and economic benefits, sometimes it is necessary to meet certain requirements while abandoning other requirements. For example, in order to improve the quality of the product, it is necessary to adopt a mold with high precision and complex structure, which will increase the mold cost and prolong the preparation period of the production. When the demand is low or the quality of the product is not high, Products of high quality requirements, try to shorten the production cycle and reduce the cost of mold, then you should adopt a variety of simple economic mold structure.
