How to clean aluminum alloy die castings?


The aluminum alloy die casting is a kind of pressure casting parts. It uses the mechanical die-casting machine equipped with the casting mould to pour the aluminum alloy heated into the liquid into the feeding port of the die-casting machine, and then through the die-casting machine to cast the aluminum alloy parts with the shape and size limited by the mould. Such parts are usually called aluminum alloy die casting.

Aluminum alloy die-casting parts have different names in different places, such as aluminum die-casting parts, die-casting aluminum alloy parts, die-casting aluminum alloy parts, die-casting aluminum, aluminum alloy die-casting parts, aluminum alloy die-casting parts, etc. Because the metal aluminum alloy has good fluidity and plasticity, and the casting process is cast in a pressure die-casting machine, the aluminum alloy die-casting can make a variety of more complex shapes, and can also make a high precision and finish, and then greatly reduce the amount of mechanical processing of the casting and the casting allowance of the metal aluminum alloy, which not only saves electricity, metal materials, but also greatly saves labor costs; Aluminum alloy has excellent thermal conductivity, small specific gravity and high machinability; Then aluminum alloy die castings are widely used in various industries such as car manufacturing, internal combustion engine manufacturing, motorcycle manufacturing, motor manufacturing, oil pump manufacturing, transmission machinery manufacturing, precision instruments, landscaping, electric power construction, construction and decoration.

Aluminum alloy die-casting can be made into aluminum die-casting car parts, aluminum die-casting car engine pipe fittings, aluminum die-casting engine cylinder, aluminum die-casting gasoline engine cylinder head, aluminum die-casting valve rocker arm, aluminum die-casting valve support, aluminum die-casting power parts, aluminum die-casting motor end cover, aluminum die-casting housing, aluminum die-casting pump housing, aluminum die-casting construction parts, aluminum die-casting decoration parts, aluminum die-casting guardrail parts, aluminum die-casting aluminum wheel and other parts.

How to clean aluminum alloy die castings?

1. To remove the sprue, overflow chute and their burrs, a punch is usually used for punching. Generally, manual operation is not required after punching. When the punch is difficult to remove, it can be removed manually, but it shall not cause meat shortage and deformation.
2. When the product needs to be refined, it can be polished with a grinder, grinding wheel grinder or polishing machine, and the parts that are not in place can be trimmed with a scraper or file.
3. In case of deformation of aluminum die castings, special mould and equipment can be used for correction. After correction, annealing or aging treatment shall be required.

Aluminum die casting plays an extremely important role in the mechanical operation and car travel, so we should pay attention to its internal quality when purchasing or sorting to ensure our long-term use.
