Description
技术领域technical field
本发明实施例涉及电子设备技术，尤其涉及一种金属壳体制备方法和金属壳体。Embodiments of the present invention relate to electronic device technology, and in particular, to a method for preparing a metal casing and the metal casing.
背景技术Background technique
在要求精度高的电子产品加工行业中对金属壳体的加工尤其对铝合金的加工技术主要是对铝合金型材全部用计算机数字控制机床(Computer numerical control，CNC)进行加工或者采用冲压和CNC共同对铝合金型材进行加工；但是上述两种加工方式在加工复杂结构的壳体时显得力不从心，CNC加工时间急剧增长造成成本上升，同时加工时间延长造成交货周期变长，会造成工作效率低下，因此现有技术中常采用压铸方式取代CNC，以降低成本并降低产品加工时间。In the electronic product processing industry that requires high precision, the processing of metal shells, especially the processing technology of aluminum alloys, is mainly to process all aluminum alloy profiles with computer numerical control (CNC) or the combination of stamping and CNC. Processing aluminum alloy profiles; however, the above two processing methods are incapable of processing shells with complex structures. The sharp increase in CNC processing time leads to an increase in cost, and the extension of processing time results in longer delivery cycles, which will result in low work efficiency. Therefore, in the prior art, die casting is often used instead of CNC to reduce costs and product processing time.
压铸技术是将铝合金在高温下熔融，然后通过高压方式将熔融铝合金压入耐高温的模具中，通过这种方式可以一次性做出复杂结构形式的壳体，并且效率高。但是，由于材料特性及压铸的致密性造成压铸出来的产品表面处理效果较差，阳极氧化后会造成表面发黑偏暗的问题。Die-casting technology is to melt aluminum alloy at high temperature, and then press the molten aluminum alloy into a high-temperature resistant mold through high pressure. In this way, a shell with a complex structure can be made at one time with high efficiency. However, due to the material characteristics and the compactness of die-casting, the surface treatment effect of die-casting products is poor, and the surface will be black and dark after anodizing.
