What is the dewaxing process of the precision casting parts?
Dewaxing precision casting is widely used for jet engines, gas turbine, steam turbine, engine, vehicle, aircraft parts, food machinery, printing machinery, paper machinery, compressors, valves, pumps, measuring instruments, sewing machines, weapons, office machines, and other machine parts.
The maximum weight of castings is about 100 kg, usually below 10 kg. The dimensional tolerances of the castings are 20mm + 0.13MM, 100mm + 0.30mm, 200mm + 0.43mm, and the size accuracy of the small parts is not within the range of + 0.10mm. The angle tolerance is + 0.5~ + 2, the minimum thickness of casting is 0.5~1.5mm, and the surface roughness of casting is about Rmax4S~12S. Precision casting material a few without any restrictions, such as Aluminum Alloy, magnesium alloy, titanium alloy, copper alloy, steel, cobalt and nickel based alloy, hard materials, making complex shape workpiece, good dimensional accuracy, less machining.
Precision casting refers to the use of non-metallic mold, the product size accuracy higher than the general sand casting mold of the general term, including dewaxing or plaster mold and ceramic mold three categories. Here we have a detailed look at it: dewaxing, precision casting: such precision casting of the maximum limit length of 700mm, easy to do, the length of less than 200mm.
