What are the performance characteristics of precision castings?

- Apr 10, 2017-

1. The maximum limit length of precision castings is 700mm, easy to make the length of 200mm or less, the maximum weight of about 100 kg, generally more than 10 kg.

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

3. Precision casting material almost no restrictions, such as aluminum, magnesium alloy, titanium alloy, copper alloy, all kinds of steel, cobalt and nickel-based heat-resistant alloy, hard materials.

4. Precision casting production of complex shape of the workpiece, the size of good precision, cutting.

5. Precision cast to save material waste, and mass production.

Dewaxing precision castings are widely used in injection engines, gas turbines, steam turbines, aircraft parts, internal combustion engines, vehicles, food machinery, printing machinery, paper machinery, compressors, valves, pump, measuring instrument, sewing machine, Transaction machines, and other machine parts.
