Characteristics And Advantages Of Precision Casting
- Apr 25, 2017 -

The precision casting is also known as the investment casting, with the other casting method and part forming method compared with the following characteristics:
1. Castings with high precision, fine surface roughness value, casting size accuracy can reach 4-6 level, surface roughness can reach 0.4-3.2 μm, can greatly reduce the machining allowance of castings, and can achieve the amount of manufacturing, reduce production costs.
2. Can be cast in the shape of complex, and difficult to use other methods of processing castings. The casting contour size is small to a few millimeters large to 1000 mm, the wall thickness is thinnest 0.5mm, the smallest hole is below 1.0mm.
3. Alloy materials are unrestricted: such materials as carbon steel, stainless steel, alloy steel, copper alloys, aluminium alloys and high temperature alloys, titanium alloys and precious metals are all available in casting. For the alloy materials that are difficult to forge, weld and cut, it is especially suitable for the production of casting method.
4. High flexibility and adaptability. Can be used for mass production, but also for small quantities and even single-piece production.
