Casting technology is a casting method that uses raw sand with certain properties as the main molding material, including various specific techniques:

1. Sand casting: a casting method for producing castings in sand molds, suitable for making blanks with complex shapes, especially those with complex inner cavities, and with low cost. ‌

2. Investment casting: also known as lost wax casting, is the process of using wax to create a wax mold for the parts to be cast, and then coating the wax mold with mud to make a mud mold. After drying the clay mold, it is baked into a ceramic mold. Once baked, all wax molds melt and are lost, leaving only ceramic molds. Usually, when making clay molds, a pouring port is left, and then molten metal is poured through the pouring port. After cooling, the required parts are made. ‌

3. Pressure casting: Using high pressure to rapidly press molten metal into a precision metal mold cavity, the molten metal cools and solidifies under pressure to form a casting. ‌

In addition, there are various technologies such as low-pressure casting.
