Lost-foam casting is a type of evaporative-pattern casting process that is similar to investment casting except foam is used for the pattern instead of wax. THE LOST FOAM CASTING PROCESS Process Steps 1. Build cluster (multiple patterns per cluster). The uniform shaping of the cluster is … The lost foam casting (LFC) process is emerging as a reliable casting method. Process Steps. The lost foam casting technology included 5 steps: designing the pattern; applying insulation painting; placing the pattern into the sand flask; pouring the molten metal; and collecting the castings. Steam heating of polystyrene beads converts into a light pattern form that is smooth, accurate, lightweight and … High dimensional accuracy can be achieved and thin sections can be cast (i.e. This dried and coated cluster is now invested in a foundry flask with loose, unbounded sand which is vibrated in order to provide a tight compaction, leaving behind the pattern/shape in the sand. The surfaces of the EPS parts are now sprayed or painted with a hard coat, where after it is placed in a mold and feeds and risers are added. This cluster is now coated with a permeable refractory coating and left to dry under very controlled conditions. 4. Now customize the name of a clipboard to store your clips. Western quality. THE LOST FOAM CASTING PROCESSCopyright 2003 © Austin Group, LLC. Now the molten metal is poured on to the top of the gating system, which is responsible for directing the molten metal through the cluster. 2. Coat cluster.

The final product can then also be heat treated or undergo other finishing operations much like what is seen in other casting processes. The feeds and risers are then removed, leaving behind the cast and completing the lost foam casting process. In most cases the pattern is molded in polystyrene (2.5% polystyrene and 97.5% air) in a closed mold. Assemble pattern if it is a multiple piece pattern. Slideshare uses cookies to improve functionality and performance, and to provide you with relevant advertising. The foam pattern is “invested” into the sand at the Fill & Compact process station allowing the sand into all voids and supporting the foam patterns external form. It is also dimensionally accurate, maintains an excellent surface finish, requires no draft, and has no parting lines so no flashis formed. 4. For smaller, high quantity parts, EPS steam injection is used to create a foam pattern. The foam used in the casting process is easy to manipulate, glue and carve - this allows freedom and flexibility in design. Clipping is a handy way to collect important slides you want to go back to later. Mold foam pattern sections. Browse more videos. Front and rear mold half are formed by the shaped faces of every sand block. After the molten metal has solidified, the casting is removed from the sand and shake-out continuous. 9.
