Characteristics of Investment Casting Process

1,High dimensional accuracy and good finish

The dimensional accuracy is best to reach 5‰ of the nominal size, and the roughness level is Ra0.8-3.2μm, which greatly reduces the workload of subsequent machining. In the case of near net shape or even net shape, machining is almost completely cancelled.

2,The casting has superior mechanical properties and low cost

Due to the superiority and stability of the process itself, the mechanical capacity of the castings can be maintained at a high level.

Lost wax precision casting is particularly suitable for complex structures. A reasonably designed single casting can sometimes replace multiple parts of equipment, which can include ordinary casting, machining, stamping, forging, injection molding, sheet metal, etc. At the same time, in view of the strong flexibility of the process, the molding is easy, and the weight of the parts can be significantly reduced, thereby greatly reducing the machining cost. In addition, it is also very conducive to saving and environmental protection.

3,Wide range of material adaptability

Silica sol lost wax precision casting is suitable for most casting alloys, including various cast iron, carbon steel, low alloy steel, tool steel, stainless steel, heat-resistant steel, nickel alloy, cobalt alloy, titanium alloy, bronze, brass, aluminum Alloy etc. And its overall processing effect is relatively stable, especially suitable for materials that are difficult to forge, weld, and machining.

4,Excellent production flexibility

It is very suitable for large batches, small batches, and even single-piece production, and sometimes there is no difference in production cost. There is no need for very complicated machinery and equipment, and the mould machining scheme is also flexible and diverse.
