Influence of mechanical vibration on the solidification of

Abstract Mechanical vibration was applied to the solidification of a lost foam cast (LFC) 356 aluminum alloy. Effects of mechanical vibration with different peak acceleration on the size and morphology of αAl phase and also on the mechanical properties of the castings were studied. Results indicated that αAl dendrites gradually


THE LOST FOAM CASTING PROCESS Process Steps. 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.

Lost Foam What is it?

Lost Foam What is it? Lost Foam is a unique casting process which is ideally suited to the manufacturing of geometrically complex parts with one cast. The main characteristic of the process as already stated in the name Lost Foam is the use of lost patterns made of organic foam materials.

EnergySaving Melting and Revert Reduction Technology (E

The lost foam casting process is a cost effective method for producing complex castings using an expandable polystyrene pattern and unbonded sand. The use of unbonded molding media in the lost foam process will impose less constraint on the solidifying casting making hot tearing less prevalent.
