Introduction:

Lost-foam casting was invented in 1964 by M.C. Flemmings. Public recognition of the benefits of LFC was made by General Motors in the mid 1980s when it announced its new car line, Saturn, would utilize LFC for production of all engine blocks, cylinder heads, crankshafts, differential carriers, and transmission cases.

LFC takes advantage of the low boiling point of foam to simplify the investment casting process by removing the need to melt the wax out of the mold. 

It has the features of low investment, high efficiency, less labor intensity, stable performance, agile production and extensive applicable scope, hence it is applicable to technical reformation in newly-built casting factory or old casting factory.  

 

 

Process & Operating principle

 

1. Mold foam pattern sections.
2. Age pattern to allow dimensional shrinkage.
3. Assemble pattern if it is a multiple piece pattern.
4. Build cluster (multiple patterns per cluster).
5. Coat cluster.
6. Dry coating.
7. Compact cluster in flask.
8. Pour metal.
9. Extract cluster from flask.

Advantages of Lost foam casting moulding machinery

 

 This casting process is advantageous for that very complex castings  would regularly require cores.

• It is also dimensionally accurate, maintains an excellent surface finish, requires no draft, and has no parting lines so no flash is formed.
• As compared to investment casting, it is cheaper because it is a simpler process and the foam is cheaper than the wax.
• Risers are not usually required due to the nature of the process; because the molten metal vaporizes the foam and the remaining metal into the mold cools more quickly, which results in natural directional solidification.
• Foam is easy to manipulate, carve and glue, due to its unique properties.
• The flexibility of LFC often allows for consolidating the parts into one integral component; other forming processes would require the production of one or more parts to be assembled.
