The main advantages of lost foam casting

1. The size and shape of the casting are accurate, the repeatability is good, and it has the characteristics of precision casting;
2. High surface finish of castings;
3. The sand core and core making department is abolished, and the casting defects and waste products caused by core making and core making are eradicated;
4. Not fitting the box and not taking the mold, which greatly simplifies the molding process and eliminates the casting defects and waste products caused by taking the mold and closing the box;
5. Adopt dry sand molding without binder, moisture, and any additives to eliminate various casting defects and waste products caused by moisture, additives and binders;
6. The sand treatment system is greatly simplified, the molding sand can be reused completely, and the molding sand preparation department and the waste sand treatment department are eliminated;
7. Sand falling is extremely easy, which greatly reduces the workload and labor intensity of sand falling;
8. No flashing burrs in castings, which reduces the cleaning and grinding workload by more than 50%;
9. A reasonably shaped riser can be set in an ideal position, which is not constrained by traditional factors such as parting and molding, and reduces the internal defects of the casting;
10. Negative pressure pouring is more conducive to the filling and shrinkage of liquid metal, and improves the microstructure density of castings;
11. Combined pouring, one box with multiple pieces, greatly improves the process yield and production efficiency of castings;
12. Reduce the processing margin and reduce the machining cost;
