Foundry Equipment Lfc Sandbox&flask For Metal Casting Production,Lost Foam Molding...

Introduction The lost foam process molding equipment originated in 1958 when H.F. Shroyer was granted a patent for a cavity-less casting method, using a polystyrene foam pattern embedded in traditional green sand. The polystyrene foam pattern left in the sand is decomposed by the poured molten metal. The metal replaces the foam pattern, exactly...

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.
