Precision casting is a casting method compared to traditional casting processes. It can achieve relatively accurate shape and high casting accuracy. A common practice is to first make the electrode of the required blank (with very little or no margin left), and then use the electrode to corrode the mold to form a cavity. Use the casting method to cast wax and obtain the original wax mold. Brush high-temperature resistant liquid sand layer by layer on the wax mold. After obtaining sufficient thickness, air dry and then heat up to dissolve the internal wax mold, obtaining a cavity consistent with the required blank. Pour molten iron into the mold cavity, and after solidification, peel off the outer shell to obtain precision manufactured products.

Investment casting, also known as investment casting, has the following characteristics compared to other casting methods and part forming methods:
1. High dimensional accuracy of castings with high surface roughness values. The dimensional accuracy of fine castings can reach levels 4-6, and the surface roughness can reach 0.4-3.2 μ m. Can greatly reduce the machining allowance of castings and achieve zero allowance manufacturing to reduce production costs
2. Castings with complex shapes that are difficult to machine using other methods can have contour dimensions ranging from a few millimeters to thousands of millimeters, with a minimum wall thickness of 0.5mm and a minimum hole diameter of 1.0mm or less
3. Alloy materials are not limited, such as carbon steel, stainless steel, alloy steel, copper alloy, aluminum alloy, high-temperature alloy, titanium alloy, and precious metal, which can be produced by precision casting. For alloy materials that are difficult to forge, weld, and cut, precision casting is particularly suitable for production
4. High production flexibility and strong adaptability, suitable for both large-scale production and small batch or even single piece production
