main advantages
The main advantages of the disappearing model casting process
1.The dimensions and shapes of the castings are precise and have good repeatability, featuring the characteristics of precision casting.
2. The casting surface has high smoothness
3. Without boxing or taking molds, the molding process is greatly simplified, eliminating casting defects and waste caused by mold taking and box.
4. The castings have no burrs or spurs, reducing the cleaning and grinding workload by more than 50%.
5. Negative pressure pouring is more conducive to the filling and secondary pouring of liquid metal, thereby improving the microstructure density of the castings;
6. It reduces the machining allowance and lowers the processing time cost;
7. The shape of the parts is not restricted by the traditional casting process, liberating the mechanical design workers, enabling them to freely design the most ideal casting shape according to the performance of the parts;
8. It can reduce the weight of the castings and lower the production cost;
9. The process is widely applicable, not only suitable for cast steel and cast iron, but also for cast copper, cast aluminum, etc.;
10. The process is not only applicable to castings with simple geometric shapes, but also more suitable for castings with multiple openings, multiple cores, and complex geometric shapes that are difficult to handle in ordinary casting;
11. When pouring in dry sand, the sand can be removed easily and the temperature is uniform. Therefore, the residual heat can be utilized for heat treatment.
12. Using the lost foam casting process, any size of casting can be produced based on the melting capacity.
13. Lost foam casting is suitable for batch casting. The dry sand mold can be easily removed from the casting, and for certain types of castings, residual heat treatment can also be carried out according to the demand.
