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 castings can be made into aluminum die-cast car parts, aluminum die-cast car engine pipe fittings, aluminum die-cast engine cylinders, aluminum die-cast gasoline engine cylinder heads, aluminum die-cast valve rocker arms, aluminum die-cast valve seats, aluminum die-cast power accessories, aluminum die-cast motor end caps, aluminum die-cast housings, aluminum die-cast pump housings, aluminum die-cast construction accessories, aluminum die-cast decoration accessories, aluminum die-cast guardrail accessories, aluminum die-cast aluminum wheels, 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.

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.
