Explanation of performance characteristics of precision castings

The performance characteristics of precision castings are as follows:

1. High dimensional accuracy, up to 20mm±0.13mm, 100mm±0.30mm, 200mm±0.43mm.

2. The surface roughness is low and the surface thickness is about Rmax4S12S.

3. The angle tolerance is ±0.5±2.0 degrees, and the dimensional accuracy of small parts is not easy to reach within ±0.10mm.

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

5. The shape is complex, saving material waste, and can be mass-produced.
