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.

A good mold material for casting resin is flexible and inert, with excellent heat and chemical resistance. It is even better if it has remarkable detail replicating abilities. Silicone is especially popular and often considered the best, but latex, polyurethane, and even gypsum plaster will work.

Casting resin is a low-viscosity epoxy resin, which consists of two components: the actual resin and the matching hardener. When these two components are mixed, a chemical reaction occurs, which causes the mass to harden for some time. And this brings us to the special features of casting resin – its thin consistency.

Casting resins are pourable plastic or elastomer compounds that are used to cast parts, make molds, or form structures in place. They are mixed with a hardener, catalyst, or activator and then poured into the sprue of open molds.
