Aluminum Alloy Die Casting

Aluminum alloy die casting is one of the most efficient metal forming technologies. It has the advantages of high production efficiency, complex casting shape and high precision. Therefore, it is widely used in many fields such as automobile industry, aerospace, 5G communication equipment, etc. With the development of modern industry, aluminum alloy die casting process and die casting equipment are constantly upgraded, and various industries have higher and higher requirements for the quality, performance and precision of die-cast aluminum parts.

The advantage of the aluminum die casting process is that the surface is smoother and has higher dimensional consistency than other casting technologies. Mastering the excellent surface treatment process of the entire die casting process can effectively reduce a series of surface defects caused by die castings. Product surface defects not only affect the appearance of the product, but also affect the use effect of the product to a certain extent.

There are several main reasons for the surface defects caused by aluminum alloy die casting:

The mold and die casting have problems such as adhesion, bubbling, and cracking;

The casting is deformed during the die casting machine processing;

The cleaning fluid of the cleaning process has a certain corrosive effect, which causes the product to be corroded and blackened.

In order to solve this pain point, HY achieves phosphorus-free and heavy metal-free production line through phosphorus-free cleaning + chromium-free passivation, so that the product has chromium-free passivation with the performance of chromium passivation film. At the same time, we use independent research and development and adjustment for release agents and cutting fluids to reduce chemical pollution while the liquid flow rate is uniform without bubbles, pinholes and other defects. At present, we have reached cooperation with customers in the fields of communication heat sinks, automotive accessories, etc. and have received good reviews.
