Advantages of lost foam castings

1. The size and shape of the casting are accurate, the repeatability is good, and it has the characteristics of precision casting;

2. The surface finish of the casting is high;

3. Lost foam eliminates the sand mold and core making department, and eliminates casting defects and waste products caused by core making and core setting;

4. The out-of-box and no mold-taking greatly simplifies the molding process and eliminates casting defects and waste products caused by mold-taking and closing;

5. The lost foam adopts dry sand modeling without binder, moisture and any additives, which eliminates various casting defects and waste products caused by moisture, additives and binders;

6. The lost foam greatly simplifies the sand processing system, the molding sand can be all reused, and the molding sand preparation department and waste sand treatment department are eliminated;

7. Shaving sand is extremely easy, which greatly reduces the workload and labor intensity of sand falling;

8. The casting has no flash and burr, which reduces the cleaning and polishing workload by more than 50%;

9. The pouring riser of reasonable shape can be set at the ideal position, which is not restricted by traditional factors such as parting and mold taking, and reduces the internal defects of the casting;

10. Lost foam negative pressure pouring is more conducive to filling and feeding of liquid metal, and improves the density of the structure of the casting;

11. Combined pouring, multiple parts in one box, greatly improving the process yield and production efficiency of castings;

12. Reduce the machining allowance and reduce the machining cost;

13. Lost foam is easy to realize mechanized automatic assembly line production, and the production line is flexible. It can realize the production of different alloys, different shapes, and different sizes of castings on one production line.
