Precision investment casting

Sand casting production of precision castings, surface finish, the density of material and microstructure and mechanical properties are often poor, so when casting these performance requirements higher, other casting method should be used, such as casting, lost wax casting, die casting, low pressure casting, and so on, edited by the company to introduce the below:
Characteristics and advantages of precision casting:
Precision casting is also known as investment casting. Compared with other casting methods and parts forming methods, investment casting has the following characteristics:

1. The casting dimension precision is high, the surface roughness value is fine, the casting dimension precision can reach 4-6, the surface roughness can reach 0.4 to 3.2μm, can greatly reduce the machining allowance of the casting, and can realize the no-margin manufacturing, reduce the production cost.

2. Castings with complex shapes that are difficult to be processed by other methods can be cast. The casting outline size is small to a few millimeters to thousands of millimeters, the wall thickness is the thinnest 0.5mm, the smallest hole is less than 1.0mm.

3. Alloy materials are not limited: such as carbon steel, stainless steel, alloy steel, copper alloy, aluminum alloy and high temperature alloy, titanium alloy and precious metals and other materials can be produced by investment casting. For alloy materials that are difficult to forge, weld and cut, it is especially suitable for investment casting.

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 for complex products and quick investment. Thus, it is in a favorable position in the competition with other technologies and production methods and has a bright future.
