Several common process methods in precision casting

Precision casting, as a high-precision metal forming technology, is widely used in multiple industrial fields. Next, we will introduce several common process methods in precision casting:

Investment casting: This is a long-standing process specifically used to manufacture metal parts with complex shapes and high precision requirements. The castings produced by this method have stable shapes, precise dimensions, and superior surface quality.

Die casting method: In this process, metal is pressed into a finely designed mold under high pressure, resulting in castings with highly accurate shape and size. Die cast parts not only have a stable structure, but also have a smooth and delicate surface.

Injection molding method: Molten metal is rapidly injected into a mold under high pressure, and then rapidly cooled and solidified to form high-precision castings. This method is particularly suitable for producing small to medium-sized complex and fine castings.

Lost wax casting method: This process involves carefully coating ceramic and other materials on a wax mold to form a casting mold, followed by metal casting. This method can create castings with intricate internal structures and extremely high precision in appearance.

The above precision casting processes each have their own characteristics and can be flexibly selected according to different production needs and material characteristics, jointly promoting the continuous progress of precision casting technology and the expansion of application fields.
