How to clean aluminum alloy die castings
Aluminum alloy die-casting is a kind of pressure-casting parts. It uses a pressure-casting mechanical die-casting machine equipped with a casting mold. The aluminum alloy heated to a liquid state is poured into the feeding port of the die-casting machine. The shape and size of aluminum alloy parts, such parts are usually called aluminum alloy die castings.
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. Since 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 various complex shapes, and can also make high precision and smoothness. , and then greatly reduces the machining amount of castings and the casting allowance of metal aluminum alloys, which not only saves electricity, metal materials, but also greatly saves labor costs; and aluminum alloys have excellent thermal conductivity and a small specific gravity. And high machinability; then aluminum alloy die castings are widely used in car production, internal combustion engine production, motorcycle production, motor production, oil pump production, transmission machinery production, precision instruments, landscaping, power construction, building decoration and other industries.
Aluminum alloy die-casting parts 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 seat, aluminum die-casting power accessories, aluminum die-casting Motor end cover, aluminum die-casting housing, aluminum die-casting pump housing, aluminum die-casting building accessories, aluminum die-casting decoration accessories, aluminum die-casting guardrail accessories, aluminum die-casting aluminum wheels and other parts.
How to clean aluminum alloy die castings?
1. To remove runners, overflow grooves and their burrs, punching is usually used. After punching, there is generally no manual work. When the punch is difficult to remove, it can be removed by hand, but it must not cause lack of meat and deformation.
2. When the product needs to be refined, it can be polished with a grinding machine, a grinding wheel grinder or a polishing machine, and the parts that are not in place are trimmed with a scraper and a file.
3. When the aluminum die casting is deformed, it can be corrected with special molds and equipment. After correction, annealing or aging treatment should be required.
