Aluminum alloy casting process
The aluminum casting is a device device of pure aluminum or aluminum alloy obtained by a casting process. Generally, a sand mold or a metal mold is used to pour aluminum or aluminum alloy heated to a liquid state into a cavity, and the obtained aluminum parts or aluminum alloy parts of various shapes and sizes are generally referred to as aluminum die castings.
About aluminum alloy casting process (sand casting)
Sand castings are the most popular and simplest types of castings that have been used for centuries. Sand casting is used to make sand castings for large parts such as grey cast iron, ductile iron, stainless steel and other types of steel. The main steps include painting, moulding, core making, styling, melting and pouring, cleaning and more.
mapping:
The traditional method is to take the foundry drawings and then send the drawings to the foundry. This process can be done in the quotation. Today, more and more customers and foundries use computer-aided design instead.
Mold:
In sand casting, the mold is made of wood or other metal materials. In this process, we asked our engineers to make the mold size slightly larger than the finished product, and the difference is called the shrinkage allowance. The purpose of this is to melt the metal into the mold to ensure that the molten metal solidifies and shrinks, thereby preventing voids in the casting process.
Core:
The core is formed by casting resin sand into a mold to form a casting of the inner surface. Therefore, the gap between the core and the mold eventually becomes a casting.
forming:
A mold is required during the smelting process. Molding typically involves the support frame of the mold, which is pulled out to separate during the casting process, where the previously placed core melts in the mold and then closes the die opening.
clean:
The purpose of cleaning is to remove sand, sand and excess metal in the casting. Welding, sand removal can improve the appearance of the casting surface by burning the sand and the scale is removed to improve the appearance of the surface of the casting. Excess metal and other risers are removed. Further steps such as welding and grinding. Finally check the defects and the overall quality.
sort out:
Before processing, re-processing. According to the requirements of different customers, we can do heat treatment, surface treatment, additional inspection and so on.
