How to make a heat sink

Different brands and models of products have different requirements for aluminum heat sinks, which are specifically reflected in shape, size, and appearance treatment. some people who have been exposed to the heat sink processing of aluminum alloy profiles know that there are two processing techniques in the industry, that is, CNC processing and die-casting processing, both of which are the technology of processing raw materials into expected products, but many people do not know much about them, MK will show you the difference between CNC processing and die-casting processing of custom heat sink.

CNC machining refers to numerical control machining, which is precision machining under computer digital control. Under this machining process, products can achieve some extremely special or complex surface treatments, such as beveling, non-penetrating pattern or texture engraving, punching at the end of the heat sink, non-flat surface treatment of the whole plane, etc. it can be said that even the most demanding and difficult details can be completed under the processing of CNC machining.

For those with aluminum alloys Manufacturers with personalized and extremely high requirements for the processing and customization of aluminum profile radiators generally, inevitably use this one. The die-casting process uses the inner cavity of the mold to apply high pressure to the molten metal to form a surface effect similar to that of the mold. Under the die-casting process, some simple Compared with CNC machining, the cost of punching and pattern forming is lower, but it cannot perform the extremely complex surface treatment. These two processing techniques of aluminum alloy radiators have their own characteristics, both of which are produced by aluminum alloy radiator manufacturers during production and operation. The indispensable skills, the two can achieve complementary effects, allowing manufacturers to provide customers with high-quality services. Of course here Not as many people think, that CNC machining is the best. In order to produce and process qualified aluminum alloy radiators, The corresponding processing technology should be selected according to its production needs, and the production cost must also be considered. It is natural to choose which one is more convenient and profitable, not whichever one looks better. After all, the cost is always a part that we cannot ignore.
