1. The factory design is simplified, fixed assets investment can be reduced by 30-40%, floor area and building area can be reduced by 30-50%, and power consumption can be reduced by 10-20%;
2. Reduced dust, smoke, and noise pollution, greatly improved the working environment for casting workers in the lost foam machine factory, and reduced labor intensity;
3. The surface smoothness of the lost foam casting machine is high, the casting size and shape are precise, the repeatability is good, and it has the characteristics of precision casting; Easy to implement mechanized automatic assembly line production, with high elasticity of the production line, capable of producing castings of different alloys, shapes, and sizes;
4. The lost foam casting accessory process is not only suitable for castings with simple geometric shapes, but also for castings with multiple edges, cores, and complex geometric shapes that are difficult to handle in ordinary casting; The shape of the parts is not limited by traditional casting processes, freeing mechanical designers to design ideal casting shapes based on the performance of the parts; Cancelled the sand core and core making departments, and eliminated the casting waste caused by core making and cutting;
5. Not fitting the box or removing the mold can eliminate the draft angle, greatly simplifying the molding process, reducing the weight of castings, and minimizing casting waste caused by mold removal and box fitting;
6. Adopting a dry sand molding without binder, moisture, or any additives, except for various casting defects and waste caused by moisture, additives, and binders;
7. Reasonable shaped sprues can be set up in ideal locations, without being constrained by traditional factors such as parting and mold selection, reducing internal defects in castings;
8. Negative pressure casting is more conducive to the filling and shrinkage of liquid metal, and improves the density of the casting structure;
9. Combination casting, with multiple pieces in one box, greatly improves the process yield and production efficiency of castings;
10. It is easy to sand, and all the molding sand can be reused, which greatly simplifies the sand processing system, eliminates the sand preparation and waste sand processing departments, and greatly reduces the workload and labor intensity of sand removal;
11. The absence of burrs and flying edges in castings reduces cleaning and polishing workload by more than 50%, reduces machining allowance, and lowers machining costs;
12. The service life of metal molds can reach over 100000 times, reducing the maintenance cost of molds;
13. Simplify process operations and reduce the requirement for workers’ technical proficiency;
14. The lost foam casting equipment process is widely used, not only for cast steel and iron, but also for copper casting, aluminum casting, etc;
15. The lost foam casting process can achieve pouring under microseismic conditions, promote the formation of special required metallographic structures, and improve the internal quality of castings;
16. Dry sand combination pouring, easy sand removal, synchronized temperature, and waste heat can be used for heat treatment. Especially the water cutting treatment of high manganese steel castings and the solid solution treatment of heat-resistant castings have very ideal effects, which can save a lot of energy and shorten the processing cycle.
