1. Gravity Casting | Gravity Casting
It refers to the process of injecting molten metal into a mold under the action of the earth's gravity, also called casting. The molten metal is generally poured into the gate manually, and the product is obtained by filling the cavity, exhausting, cooling, and opening the mold by its own weight.
Gravity casting has the advantages of simple process, low mold cost, less internal pores, and heat treatment, but at the same time, it has the disadvantages of poor compactness, weaker strength, unsuitable for producing thin-walled parts, low surface finish, low production efficiency, and high cost.
2. Die Casting (Die Casting) | Die Casting
Under the action of high pressure, the liquid or semi-liquid metal fills the cavity of a die-casting mold (die-casting mold) at a higher speed, and is formed and solidified under pressure to obtain a casting.
