Resin casting is a method of casting where a mould is filled with a liquid synthetic resin, which then hardens. The synthetic resin for such processes is a monomer for making a plastic thermosetting polymer. During the setting process, the liquid monomer polymerises into the polymer, thereby hardening into a solid.
