The corrosion phenomenon in wheel mold during low pressure die casting process was investigated with optical microscope and scanning electron microscope. The results show that the surface of mold cavity reacts with high-temperature aluminum liquid after coating falling off, which results in soldering in the mold surface. Then, the transition layer is formed and it composes of Fe-Al-Si intermetallic compound. Finally, after the cyclic action of high-temperature aluminum liquid, the transition layer continuously diffuses and falls off from the mold surface, and it eventually causes corrosion of the mold.

Stainless steel is the best choice for alloy wheel mold use. It does not rust easily. It is very strong and lasts a long time. It works well even in tough places. Picking the right material is very important. It affects how long the mold lasts. It also affects how good each alloy wheel mold is. Superband Mould​ uses new technology to make molds. They know a lot about making alloy wheel molds and die casting molds. They give car makers molds that last a long time. Read More
