Shell Molding Castings Process
Probably the earliest most automated and most rapid of mold and core making processes was the heat-curing technique known as the Shell Molding process.
Resin-bounded silica sand is placed onto a heated pattern for a predetermined time. Ejector pins enable the mold to be released from the pattern and the entire cycle is completed in seconds depending upon the shell thickness. The two halves of the mold, suitably cored, are clamped together prior to the pouring of the metal.
Shell molds may be stored for long periods if desired. Because of pattern cost this method is best suitable for volume production.
Shell Molding molds may be stored for long time. Good casting detail, appearance and dimensional accuracy. Sand molds is light in weight.
High pattern cost, higher material cost compared to green sand molding. Not suitable for big castings.
