Lost foam casting (large aluminum mold machining) production principle

December 01, 2023

【China Aluminum Industry】 Lost Foam Casting (Large Aluminium Mold Processing) Firstly, a foam model is made according to EPC technology, special paint is applied, dried and placed in a special sand box, filled with dry sand, three-dimensional vibration is tight, and pumped. Casting under vacuum, the model gasification disappeared, the metal replacement model, and the same casting as the foam mold was reproduced. After condensation, the vacuum was released, and the casting was taken out of the loose sand for the next cycle.

1. Making bubble plastic gasification molds (manual, mechanical);

2, bubble plastic gasification, mold drying after combination;

3, bubble plastic mold surface brush, spray fire-resistant paint after drying again (a certain dry);

4. Place the special sand box on the three-dimensional vibration table;

5. Fill in low-sand (dry sand) vibration and scrape;

6. Put the dried foaming gasification mold on the bottom sand, divide it into sand according to the process requirements, and automatically smooth the box mouth after a certain period of time;

7. Cover the mouth of the sand box with a plastic film, place a sprue cup, and then use a negative pressure system. After the compaction, the liquid steel casting is performed, the foamed plastic gasification mold disappears, and the molten metal replaces its position;

8. After the casting is condensed, release the vacuum and turn it over. Take out the casting and proceed to the next cycle.

Nanjing Transit large mold processing center, lost foam casting (large aluminum mold processing), in the bubble plastic mold technology, can be designed and processed in accordance with the requirements of various models, high precision, more convenient, is your mold casting industry's preferred.
