Product process

Sand casting is a method of making a casting mold with sand, and relying on the fluidity of the liquid alloy itself to fill the mold cavity under the action of gravity to produce castings. Generally speaking, it is the casting method of sand compaction. Most non-ferrous alloy castings such as steel and iron can be obtained by sand casting. Single-piece production, batch production and mass production can be adapted, and it is the basic casting production method.

The mold in casting production refers to the casting mold, which is pre-prepared according to the shape and performance requirements of the casting, and is used to inject molten metal and cool and solidify it to form the casting process equipment; the casting mold made of sand is called sand mold. The composition of sand mold is usually composed of upper mold and lower mold, parting surface, core, cavity and pouring system.

The material for making sand molds is called molding material, the molding material used for making sand molds is called molding sand, and the molding material used for making sand cores is called core sand. The quality of molding sand and core sand directly affects the quality of castings. Poor quality of molding sand will cause casting problems such as pores, blisters, sticky sand, and sand inclusion.

Sand casting is an ancient casting method. There are many sources of materials for sand casting. The manufacturing method of sand casting contains many traditional manufacturing processes, with rich means, flexible processes and strong adaptability to production. Most of the above products in the foundry industry are sand casting. Completed.
