The difference between CNC machining and die casting machining of aluminum enclosure

We all know that different brands and models of products have different requirements for aluminum box, which are reflected in the shape, size and appearance treatment. Those who have been exposed to aluminum enclosure processing will know that there are two processing technologies in the industry. , that is CNC machining and die-casting machining, both of which are technologies for processing raw materials into expected products, but many people do not know the difference between the two.

1. First of all, the processing methods are different. CNC processing is index-controlled processing, which is precision machining under computer digital control. The aluminum casing can achieve some extremely special or complex surface treatments under this processing technology, such as beveling, Non-penetrating pattern or texture engraving, punching treatment at the bend of aluminum shell, surface treatment of non-flat surface, etc.

Die casting is the process of applying high pressure to molten metal using the cavity of the mold to create a surface effect similar to that of the mold.

2. Secondly, the processing difficulty is different:

CNC machining can be said that even the most demanding and difficult details can be completed under the processing of CNC machining.

Die casting can only perform some simple punching and pattern forming work, which is cheaper than CNC machining, but cannot perform very complex surface treatment.

To sum up, it can be seen that if you want to produce a qualified precision aluminum case, you need to choose the corresponding processing technology according to its production needs.

In addition, the production cost must be taken into account. When both processing techniques are feasible, it is natural to choose which one is more convenient and profitable. After all, the actual needs of oneself are also very important.
