1. The maximum limit length of precision casting shall be 700mm, the easily made length shall be less than 200mm, and the maximum weight shall be about 100kg, usually less than 10kg.

2. The dimensional tolerances of precision casting are 20mm±0.13mm, 100mm±0.30mm and 200mm±0.43mm, while the dimensional accuracy of small parts is not easily within ±0.10mm.The Angle tolerance is ±0.5~±2.0 °, and the minimum thickness of precision casting is 0.5~1.5mm.Surface roughness of precision casting is about Rmax 4S~12S.

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

4. The precision casting can make the workpiece with complex shape, good dimension accuracy and machining.

Precision casting saves material waste and can be produced in large quantities.

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, meters, sewing machines, weapons, service machines, and other machine parts.Precision casting
