What are the methods and characteristics of precision casting?

　 What are the advantages and characteristics of dewaxing precision casting? The following text will provide a detailed explanation for everyone.
Precision casting method refers to the general term for casting methods that use non-metallic molds to achieve dimensional accuracy higher than ordinary sand mold castings, including dewaxing method, gypsum mold method, and ceramic mold method.
Dewaxing precision castings are widely used in jet engines, gas turbines, steam turbines, aircraft parts, internal combustion engines, vehicles, food machinery, printing machinery, paper making machinery, compressors, valves, pumps, measuring instruments, sewing machines, weapons, office machines, and other machine parts.

Characteristics and advantages of dewaxing method in precision casting
(1) Casting The limit length is 700mm, and the easy to make length is below 200mm. Casting The weight is about 100 kilograms, usually below 10 kilograms.
(2) The dimensional tolerances of castings are 20mm ± 0.13mm, 100mm ± 0.30mm, 200mm ± 0.43mm, while the customized dimensional accuracy of Shaanxi precision castings for small parts is not easily within ± 0.10mm. The angle tolerance is ± 0.5~± 2.0 degrees, and the casting has a small thickness of 0.5~1.5mm. The surface roughness of the casting is about Rmax 4S~12S
(3) There are almost no restrictions on the material of castings, such as aluminum alloy, magnesium alloy, titanium alloy, copper alloy, various types of steel, cobalt based and nickel based heat-resistant materials
Alloy, hard material.
(4) Produce workpieces with complex shapes, good dimensional accuracy, and minimal cutting.
(5) Save material waste and enable mass production.
