- High precision and low roughness
It is better that the precision of cast dimension can be up to be 5‰ of the nominal dimension and the roughness can be up to Ra0.8-3.2μm so that the subsequent machining can be easier. When it is the final-construction or near the final-construction, all the machining can be cancelled off.
- Superior performance and low cost
Due to the superiority of the investment casting, the mechanical property can be maintained very well.
Investment casting is extremely suitable for producing parts with complicated construction. The single cast with good design can substitute for the parts with many different constructions so that some traditional procedure such as stamping, calcination, machining, welding etc. Because of the strong flexibility of investment casting, it is easily to be shaped and the weigh can be reduced much. The overall cost can be decreased as well.
- Wide choices of cast materials
Most cast alloy is suitable for investment casting, including cast iron, carbon steel, low alloyed steel, tool steel, stainless steel, heat-resisting steel, nickel-steel, cobalt alloy, titanium alloy, bronze, brass, aluminium alloy etc, especially for the materials that is hard to be calcinated, soldered and mechanical tooling.
- Flexibility production
Investment casting does not need complicated equipments, and the cast mold and tooling method is various. Therefore, it is extremely fit for the production with various kinds and small volume.
- Fine Surface
The cast can realistically reflect the mold structiure. Accordingly, Letters and pictures can be stamped on the cast surface, which can upgrade the artistic value of the products.
