How To Shrink a Casting using NOVOCS Silicone Solvent
Step 1: Gathering Materials / Preparing Model for Molding
It is possible and extremely easy to reduce the size of an original without any special equipment. Comparison of original sized model measuring 3” (7.6 cm), a casting out of a mold reduced in size to yield a casting that is 2 3/8” (6 cm) and a casting out of a mold reduced to yield a casting that is 1.9” (4.8 cm).
