Lost foam casting moulding machinery

This process 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, 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.

MAIN EQUIPMENTS

•Vacuum stablized system:

•Molding system:

•Sand reclamation system

Advantages of Lost foam casting moulding machinery

• This casting process is advantageous for very complex castings that 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 the first metal into the mold cools more quickly than the rest, 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.
