High-Efficiency Precision Casting for Metal Parts with Wide Adaptability and Flexible Production

Casting is a common metal hot processing process, which can process metal materials into parts or blanks with certain shapes, sizes and properties.

The principle of casting is to melt the metal into liquid, then pour it into a cavity with a specific shape, cool and solidify, and clean it to get the required casting.

There are two main types of casting methods: sand casting and special casting.

Sand casting refers to casting with natural sand or artificial sand as the main molding material. It has simple molding and low cost, and is suitable for castings of various materials and specifications.

Special casting refers to casting with materials or methods other than sand as molding materials. It has precise molding and high quality, and is suitable for castings with complex shapes or high requirements.

Special casting can be divided into metal mold casting, investment casting, ceramic mold casting, centrifugal casting, pressure casting, etc.

Casting is to fill the metal in liquid state, which can produce parts with complex shapes and multiple cavities. It has wide adaptability, flexible production, can use various metal materials, low cost and high efficiency.

However, casting also has some disadvantages, such as oxidation, inclusions, segregation and other defects that are easy to occur during the melting and solidification process of the metal, which affects the metal's organizational structure and performance, and the internal organization of the casting is uneven, with defects such as pores, cracks, and shrinkage.

Casting is mainly used in agriculture, construction, water conservancy, mining, light industry, home appliances and other fields. Common castings include pipe fittings, flanges, pump bodies, valve bodies, machine tool beds, frames, fan impellers, motor housings, pressure vessels, stoves, pots, iron art, sculptures, etc.
