The use of ceramic foundry sand in precision casting is mainly based on the application of ceramic foundry sand shell technology, from the initial bucket teeth of construction machinery to the current valve plumbing and other general parts, from automobile spare parts to tool hardware parts, from cast iron, cast carbon steel to stainless steel, heat-resistant steel and non-ferrous alloys, which extends to the original sand casting, metal casting and precision casting. Good economic and social benefits have been achieved. At present, it has been widely used in the following three fields:
1, Ceramic foundry sand precision casting partly replaces the lost wax casting process, especially for some castings with relatively simple shape and some castings requiring cores, etc.
2, The ceramic foundry sand shell precision casting process is used to improve the process adaptability in the case of original quartz sand shell casting.
3, In order to improve the quality of castings, reduce the consumption of moulding sand and increase the production efficiency of castings, the small steel castings produced by ordinary sand mould technology are replaced by the new precision casting technology of ceramic foundry sand shell mould.
Advantages of Precision Casting Technology of Ceramic foundry Sand Shell Mold
1, The precision casting technology of ceramic foundry sand shell mold be widely used in cast steel, cast iron, stainless steel, low alloy steel, non-ferrous alloys in the casting of small and medium castings.
2, The adoption of the precision casting technology of ceramic foundry sand shell mold can greatly improve the market reaction speed and production efficiency.
3, Using The precision casting technology of ceramic foundry sand shell mold, the dimensional accuracy of castings can reach CT7 ~ CT6 level, and the surface roughness can be above Ra12.5. It can greatly improve the quality of sand castings, and can partly replace the lost wax precision casting process.
4, Using the precision casting technology of ceramic foundry sand shell mold , the old sand recycling method is simple, the recycling degree is high, 98% can be reused, the emission of pollutants such as solid waste is obviously reduced, and the economic benefit is obtained at the same time, which has obvious environmental protection benefit and is a sustainable development foundry technology;
5, Adopting the precision casting technology of ceramic foundry sand shell mold , the casting surface has high smoothness and is easy to be cleaned, which can obviously reduce the casting cost and obtain great economic benefit;
6, The precision casting technology of ceramic foundry Sand shell mold will become a hot spot of new practical casting technology in a considerable period of time in the future.
