The casting precision, surface finish, material density, metallographic structure, mechanical properties and other aspects of sand mold casting production are often poor, so when these properties are more required, other casting methods should be adopted, such as investment (wax loss) casting, die casting, low pressure casting, etc. Sanzhuji''''s combined experience is summarized as follows:
Features and advantages of precision casting:
Precision casting is also called investment casting. Compared with other casting methods and parts forming methods, investment casting has the following characteristics:
1. High casting dimension accuracy, fine surface roughness, casting dimension accuracy can reach 4 -- 6, surface roughness up to 0.4 -- 3.2 m, can greatly reduce the machining allowance of casting, and can realize the spare manufacturing, reduce the production cost.
2. Castable castings with complex shapes and difficult to be machined by other methods. The size of casting outline is small to several millimeters to thousands of millimeters, with the thinnest wall thickness of 0.5mm and the smallest hole of 1.0mm or less.
3. Alloy materials are not limited: Carbon steel, stainless steel, alloy steel, copper alloy, aluminum alloy and other materials such as superalloy, titanium alloy and precious metal can be produced by precision casting. For hard to forge, welding and cutting alloy material, is especially suitable for precision casting production.
4. High production flexibility and adaptability. Can be used for mass production, also suitable for small batch or even single production.To sum up, precision casting has the advantages of small investment scale, large production capacity, low production cost, simple process of complex products and quick investment effect. Thus in the competition with other technology and production mode in the advantageous position, the future is bright.
