Casting method

Sand casting: with sand as the main modeling material, the production cost is low, and it is suitable for castings of various shapes and sizes, but the surface quality of the castings is relatively poor.

Metal mold casting: The use of metal cast casting, can obtain higher dimensional accuracy and surface quality, production efficiency is also high, but the casting cost is higher, and is not suitable for castings with too complex shape.

Centrifugal casting: The liquid metal is poured into the rotating mold and solidified under the action of centrifugal force, which is often used to manufacture cylindric and other axisymmetric shapes of castings, which can effectively improve the density of castings.

Low pressure casting: The liquid metal is injected into the mold at a lower pressure, and the casting with dense tissue and good mechanical properties can be obtained, especially for large, thin-walled and complex shapes.

Lost wax casting: A precision casting method that can produce castings with complex shapes and high precision, often used to make crafts and precision parts.
