Aluminum heat dissipation pulley is precision machined and the surface is anodized

The patterns are constructed using a special mold that is heated to a specific temperature. The mold is then placed over a thermosetting resin-coated sand box. The mold is inverted, and the excess sand falls out. The resulting shell is ready to be cast. In general, shell molds are made of iron or steel, but aluminum patterns are also available for smaller production runs.

The process is most suitable for low-volume production and smaller parts. However, it requires a large amount of inert material for the mold and can produce large pieces up to twenty kilograms. Depending on the material, the heat dissipation pulley casting can produce complex forms with few blowholes or pockets. Another advantage of this process is the high level of accuracy. You can expect the cast to be accurate within a few millimeters and a few millimetres.

When it comes to casting parts for heat dissipation, the process is an efficient and effective solution. It allows manufacturers to create intricate parts up to 20kg and maintain dimensional accuracy. It also allows them to produce small parts up to 200kg/h. With the right design, this process can produce high-volume components with little or no effort. It is ideal for low-volume production. But, in some cases, the part size is too large.
