Introduction to lost foam casting, lost foam casting, and lost foam process

1. The casting size and shape have good repeatability and the characteristics of precision casting;

2. The surface smoothness of the castings is high;  

3. The disappearing mold eliminates the sand mold and core making department, eliminating casting defects and waste caused by core making and cutting;

4. Non conformity and non removal of molds greatly simplify the molding process, eliminating casting defects and waste caused by mold removal and closure;

5. The lost foam adopts a dry sand molding without binder, moisture, or any additives, eliminating various casting defects and waste caused by moisture, additives, and binders; 

6. The disappearing mold greatly simplifies the sand processing system, allowing all molding sand to be reused and eliminating the need for molding sand preparation and waste sand treatment departments; 

7. Sand falling is extremely easy, greatly reducing the workload and labor intensity of sand falling; 

8. The castings have no burrs or flying edges, reducing the cleaning and polishing workload by more than 50%;  

9. Reasonable shaped sprues can be set at ideal positions, without being restricted by traditional factors such as parting and mold taking, reducing internal defects in castings;  

10. Negative pressure casting with disappearing mold is more conducive to the filling and shrinkage of liquid metal, and improves the density of the casting structure;  

11. Combination casting, with multiple pieces in one box, greatly improves the process yield and production efficiency of castings;

12. Reduced machining allowance and lowered machining costs;  

13. Vanishing molds are easy to achieve mechanized automatic assembly line production. The production line has high elasticity and can produce castings of different alloys, shapes, and sizes on one production line

Lost foam casting (also known as full mold casting) is a new casting method that combines foam models similar to the size and shape of castings into model clusters, brushes and dries refractory coatings, buries them in dry quartz sand for vibration molding, pours them under negative pressure, vaporizes the model, occupies the position of the model with liquid metal, and forms castings after solidification and cooling.
