1. The maximum limit length of precision casting is 700mm, the easy length is less than 200mm, and the maximum weight is about 100kg, usually less than 10kg.

2. The dimensional tolerance of precision castings is 20mm 0.13mm, 100mm 0.30mm, 200mm 0.43mm, while the dimensional accuracy of small pieces is not easy to reach within 0.10mm. The Angle tolerance is 0.5~ 2.0 degrees, and the minimum thickness of precision casting is 0.5~1.5mm. The surface roughness of precision casting is about Rmax 4S~12S.

3. There are almost no restrictions on precision casting materials, such as aluminum alloy, magnesium alloy, titanium alloy, copper alloy, various steels, cobalt-based and nickel-based heat-resistant alloys and hard materials.

4. Precision castings are used to make workpieces with complex shapes, good dimensional accuracy and cutting.

5. Precision casting saves material waste and can be mass produced.

Dewaxing precision castings are widely used in jet engines, gas turbines, steam turbines, aircraft parts, internal combustion engines, vehicles, food machinery, printing machinery, paper machinery, compressors, valve parts, pumps, gauges, sewing machines, weapons, service machines, and other machine parts.
