Precision casting, also known as investment casting, can obtain relatively accurate shape and high casting precision, which is a casting method relative to the traditional casting process.So what are the characteristics and advantages of precision casting parts?Follow Dongying Highyond Investment Casting Co,LTD. For a detailed understanding of it.

If you want to understand the characteristics of precision casting, you must first know the production method of precision casting: first make the required blank electrode, and then use the electrode to corrode the mold, forming a cavity;Then the wax is cast by casting method to obtain the original wax mold.In the wax mold layer by layer brush on the high temperature resistant liquid sand;After obtaining sufficient thickness, air dry, and then heat up, so that the internal wax mold dissolved, to obtain the same as the desired blank cavity.Pour the molten iron in the mold cavity, peel off the shell after solidification, and you can get the finished precision casting!Therefore, precision casting parts have the following characteristics and advantages:

1, precision casting parts of high precision.As we all know, the casting dimensional accuracy is high, the surface roughness value is fine, the casting dimensional accuracy can reach 4-6, the surface roughness can reach 0.4-3.2μm, the precision casting can greatly reduce the machining allowance of the casting, and can realize the infinite manufacturing, reduce the production cost.

2, precision casting can cast complex shape, and difficult to use other methods of processing castings.The casting profile size can be as small as a few millimeters to thousands of millimeters, the thickness of the wall is the thinnest 0.5mm, and the smallest hole is 1.0mm or less.

3, precision casting parts of the production of high flexibility, strong adaptability, it can be used for mass production, but also suitable for small batch or even single production.

4, the use of a wide range of precision casting, not limited by the material.The following materials can be used for precision casting: carbon steel, stainless steel, alloy steel, copper alloy, aluminum alloy, high temperature alloy, titanium alloy and precious metal, etc.Precision casting is especially suitable for alloys that are difficult to forge, weld and cut.
