Process characteristics of investment casting

Edit:Xiangyang Liqiang Machinery Co., Ltd.UpDate:2019-09-04

1. Investment precision casting has 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. This 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 molding cost

Due to the superiority and stability of the process, the mechanical properties of the casting 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 powerful flexibility of the process, the molding is easy, and the weight of the parts can be significantly reduced, thereby greatly reducing the processing cost. In addition, it is also very conducive to saving and environmental protection.

Three, a 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 machine. 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 mechanical equipment, and the mould processing scheme is also flexible and diverse.
