What is resin in molding?

Resin casting is a method of plastic casting where a mold is filled with a liquid synthetic resin, which then hardens. It is primarily used for small-scale production like industrial prototypes and dentistry. During the setting process, the liquid monomer polymerizes into the polymer, thereby hardening into a solid.
