Precision casting is a casting technology that can obtain high-precision and high-quality castings. There are many types of processes, and different classification methods will have different numbers of types. Based on the provided reference information, the following are several common precision casting processes:

Classified by shell material:

Water glass shell technology

Ethyl silicate shell process

Silica sol shell technology

Classified by special casting methods:

investment casting

Gypsum casting

Ceramic casting

epc

metal casting

Die casting

low pressure casting

counter-pressure casting

Vacuum suction casting

squeeze casting

Centrifugal Casting

Continuous Casting

Semi continuous casting

shell moulding

Graphite casting

Electroslag casting

Stainless steel precision casting is classified by process form:

Plunger pressurization

Direct punch squeezing

Indirect punch extrusion (upper extrusion method and lower extrusion method)

Common processes for precision casting parts processing:

Die casting process

investment casting process

Liquid metal casting process

Fine wax loss casting process (soluble capillary casting)

These processes each have their own characteristics and are suitable for different casting shapes, sizes, and material requirements. In practical applications, the most suitable casting process will be selected based on factors such as the complexity of the casting, precision requirements, production batch size, and cost.
