Scope

Main technical content: Based on the relevant provisions of Chongqing Changan Automobile Co., Ltd.'s enterprise standard "Technical Standards for NC Machining of Automotive Cover Molds", this standard integrates the practical experience of NC machining of automotive cover molds from Chongqing Pingwei Automotive Technology Co., Ltd., Chongqing Qingling Mold Co., Ltd., Chongqing Dajiang Zhixin Mold Industry Co., Ltd., Chongqing Lingyan Mold Co., Ltd., Chongqing Yuanchuang Automotive Whole Line Integration Co., Ltd., Chongqing Yuanxiang Machinery Co., Ltd., Chongqing Minxing Mold Co., Ltd., Chongqing Xiangli Machinery Co., Ltd., Changsha Zhongteng Metal Materials Technology Co., Ltd., and Sichuan Zhongao Technology Co., Ltd. It formulates technical requirements for mold clamping, structural processing, single-piece processing of mold components, and surface processing of molds for automotive cover stamping molds. With the continuous updating and replacement of various models in the automotive industry, the demand for the development of automotive parts and tooling molds is increasing. Driven by the short-cycle development of molds and tooling, it is necessary to integrate market resources to meet the demand for short-cycle mold development. However, different mold manufacturers have different understandings of the NC machining standards for mold features, which easily leads to inconsistent NC machining quality of molds from different suppliers, resulting in mold processing quality problems, increased NC machining and management costs, and schedule delays. Therefore, it is necessary to promote the establishment of a group technical standard for NC machining of automotive cover molds, unify the processing technical standards and quality requirements for each feature on the mold, and promote the stability and consistency of collaborative processing and manufacturing among mold manufacturers.
