The Classification of casting process
Sand casting is one of the most widely used casting process, dividing into manual wood mold and auto metal mold.
Manual Mold: Low production efficiency; Poor surface quality; Suitable for large sand casting or small simple casting parts with huge quality.
Auto Mold: High precision accuracy; good surface accuracy; high production efficiency; suitable for large quantities of small and medium castings.

Investment casting is an industrial process basesd on lost-wax casting, one of the oldest known metal-forming techniques. Investment precision casting is valued for its ability to produce components with accuracy, repeatability, verysatility and integrity in a variety of metals and high performance alloys. Many materials are suitable for investment casting; such as stainless steel alloys, brass, aluminum, carbon steel, alloy steel, etc
3.Permanent Mold Casting
Permanent mold casting is a metal casting process that employs reusable molds or permanent molds, usually made from metal. The most common process uses gravity to fill the mold. The materials are aluminum, magnesium, copper alloy, zinc, etc. Typical products are gears, splines, wheels, gear housing, pipe fittings, housing, etc
Die casting is a metal casting process that is characterized by forcing molten metal under high pressure into a mold cavity. Die casting are made from non-ferrous metals, specifically zinc, copper, aluminum, magnesium, etc. It is especially suited for a large quantity of small-to-medium-sized castings, with very good surface finish and dimensional accuracy.
