The production of aluminum casings for electronic products usually needs to find a professional and regular aluminum casing manufacturer for processing and customization, because different brands and models of products have different requirements for aluminum casings, which are reflected in the shape, size and appearance treatment. And those who have been exposed to the processing of aluminum shells will know that there are two processing technologies in the industry, namely CNC processing and die-casting processing, both of which are technologies for processing raw materials into expected products, so what is the difference between the two? What's the difference?

CNC machining refers to CNC machining, which is precision machining under the digital control of the computer. Under this machining process, the aluminum shell can achieve some very special or complex surface treatments, such as bevel cutting, non-penetrating patterns or Texture engraving, punching of aluminum housing bends, non-flat surface treatment, etc. It can be said that even the most demanding and difficult to handle details can be completed under CNC processing. For those manufacturers who have personalized and extremely high requirements for the processing of aluminum shells, it is unavoidable to use this type.

The die-casting process uses the mold cavity to apply high pressure to the molten metal to form a surface effect similar to the aluminum die casting plastic injection molds. The die-casting process can perform some simple punching and patterning tasks, which is more costly than CNC machining. Lower, except that extremely complex surface treatments are not possible.

These two processing methods of aluminum casing have their own characteristics, both of which are indispensable skills of aluminum casing processing manufacturers in production and operation. The two can achieve complementary effects and allow manufacturers to provide customers with better services. In order to produce and process qualified aluminum casings, the corresponding processing technology must be selected according to its production needs. At the same time, the production cost must be considered. When both processing processes are feasible, which one is naturally more convenient and beneficial. Lee chooses which one.

Prior to the production and processing of aluminum casings by Shangheyuan's customers, they will formulate detailed and appropriate processing plans for customers to ensure that each production requirement of the product can be met, so as to provide refined and qualified products and meticulous services.
