The working principle of casting materials is to inject molten metal into the mold, cool and solidify it, and finally get the desired shape of the part. The specific process includes the following steps:
Mold preparation: Make the corresponding mold according to the shape and size of the required part. The mold is usually made of high-temperature resistant materials such as sand, metal or ceramic.
Material preparation: Mix the metal materials in a certain proportion and heat them to melt. Commonly used metal materials include copper, iron, aluminum, tin, lead, etc.
Pouring: Inject the molten metal into the mold through the gate. The casting method can be gravity casting or pressure casting. The former relies on the weight of the metal liquid to fill the cavity, while the latter is carried out under high pressure.
Cooling and solidification: The metal liquid cools and solidifies in the mold to form the desired part shape.
Post-processing: Deburring, polishing and other treatments are performed on the solidified parts to obtain the final product.
