Casting | What is casting?
The materials most commonly used for moulding are phenol-formaldehyde, polyester and epoxy resin. The items are produced by pouring liquid resin into a mould, after which the resin is left to cure without any positive or negative pressure, and either at room temperature or at an elevated temperature. During the moulding process, it is important that no air bubbles become trapped.
