Precision casting is also called investment casting. Compared with other casting methods and part forming methods, investment casting has the following advantages:
1. The casting has high dimensional accuracy and fine surface roughness, and the dimensional accuracy of the casting can reach 4-6, which can greatly reduce the machining allowance of the casting and reduce the production cost.
2. Alloy materials are not limited: materials such as carbon steel, stainless steel, alloy steel, copper alloy, aluminum alloy, high temperature alloy, titanium alloy and precious metal can be produced by precision casting. For alloy materials that are difficult to forge, weld and cut, It is especially suitable for precision casting production.
3. High production flexibility and strong adaptability. It can be used not only in mass production, but also in small batches or even single piece production.
In summary, precision casting has the advantages of small investment scale, large production capacity, low production cost, simplification of complex product technology, and quick investment. Therefore, it is in a favorable position in the competition with other processes and production methods.
