Sand casting processing is a long-standing process method, mainly used to produce various castings. Its basic principle is to pour molten metal into a pre-prepared sand mold, and then form the desired casting after it cools and solidifies.
Losier Technology Development Co., Ltd. is a manufacturer and supplier of high-quality confidential casting aluminum.
Sand casting processing is widely used in many fields, including valve industry, medical equipment, automotive parts, power equipment, wind power equipment, injection molding machines and other fields.
Metal pouring and cutting processing of sand casting Sand casting is usually used to make sand molds. The raw material of sand molds is mainly sand, which is mixed with adhesives, water, etc.

Mold making: According to the shape and size of the casting, the mold is made using a steel template or other materials. The precision and processing quality of the mold are crucial to the precision of the sand mold and the quality of the casting.
Sand mold preparation: The sand mold is prepared by the water glass sand mold method, biomass pyrolysis method or other methods. The prepared sand mold needs to go through processes such as drying and baking to ensure its dryness and strength.
Melting and pouring: The metal material is heated to a molten state in a smelting furnace and then poured into the sand mold. During the pouring process, the melting temperature, pouring speed and pouring time need to be strictly controlled to ensure the quality of the casting.
Cooling and solidification: After the metal liquid cools and solidifies in the sand mold, the required casting is formed.
Demolding and grinding: The casting is removed from the sand mold by vibration demolding or air pressure demolding, and necessary grinding and cleaning are performed to remove surface defects and impurities.
Sand castings are widely used in the manufacturing industry, including but not limited to the following aspects:
Mechanical equipment: used to manufacture various parts and components of mechanical equipment, such as gears, bearings, housings, etc.
Automotive parts: used to manufacture various parts and components of automobiles, such as engine blocks, cylinder heads, gearbox housings, etc.
Aerospace: used to manufacture parts for aircraft, rockets and other aircraft, meeting the requirements of light weight, high strength and high temperature.
Household appliances: used to manufacture the shells and components of various household appliances, such as refrigerators, washing machines, air conditioners, etc.
Wide applicability: It can be used to manufacture parts of various shapes and sizes, suitable for different industries and fields.
Low cost: Compared with other casting methods, the equipment and process of sand casting are relatively simple and the cost is low.
Good casting performance: Aluminum has a low melting point, good casting performance and fluidity, which is conducive to casting thin-walled and complexly laid castings.
Higher precision and surface quality: By optimizing the mold design and manufacturing process, higher casting precision and surface quality can be obtained.
