Lost Foam The Foam that Turns into Gas
Lost foam casting (LFC) is a type of evaporative-pattern casting process similar to
investment casting, but it uses foam for the pattern instead of wax. This process takes
advantage of the low boiling point of foam, simplifying the investment casting process
by eliminating the need to melt the wax out of the Mold.
The Casting Process :
The Below Process Consists of 3 Stages Which Assure You Final Finish Casting
- White Part - The making of a polymer foam pattern
- Yellow Part - The Coating of the pattern
- Black Part - With help of compaction table, vaccum system and sand
processing plant
"Lost Foam" casting grants the Freedom to create cost effective
precision designs, not feasible by conventional methods
- Now a days Indian foundry industry is facing very big problem because of sand
scarcity & its disposal.
- Lost foam process is environment friendly processes with more then 95% sand
reusable in process.
- Most favorable process for mass production.
- Imparts very good surface finish.
- Can work with less machining allowances.
- Simple process with high automation.
- Weight control on finished product.
- Lost Foam Casting Process is not only fit for castings of simple geometry, but
also for multi-part, multi core castings of complex geometry which are hard to
make with existing casting technology.
- Negative pressure pouring is more in favor of filling mold and replenishing
shrinkage of liquid metals, and also enhances the internal density of casting.
