Precision casting process characteristics:
High dimensional accuracy , good smoothness
Size precision can reach 5‰of the nominal dimensions ,roughness level can reach Ra0.8-3.2um. So greatly reduce the subsequent machining work burden. In near net shape or net shape case, machined processing is almost canceled.
The superior mechanical properties of castings , low cost :
Due to the superiority and stability for the process in itself ,the mechanical properties of castings can be maintained at a high level.
Lost wax casting is particularly suitable for complex shape structure situation. Sometimes, a reasonable single casting design can instead of multiple components including common casting, machining, stamping, forging, injection molding, sheet metal etc.. At the same time, due to the strong flexibility of the process, molding is easy,so can significantly reduce the weight of parts, which greatly reduces the cost. In addition, it is also very conducive to saving and environmental protection.
The wide range of material adaptability:
Silica sol lost wax casting is suitable for most of casting alloys, including cast iron, carbon steel, low alloy steel, tool steel, stainless steel, heat-resistant steel, nickel alloy, and cobalt alloy, titanium alloy, bronze, brass, aluminum alloy etc.. And the machined processing result is relatively stable, especially suitable for difficult to forge, welding, machining material.
The excellent production flexibility:
For large batch, small batch, even single production are very suitable, sometimes there is no difference in their production cost. Complex mechanical equipment aren't need , the mold processing schemes are also flexible.
