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. It can be done by amateur hobbyists with little initial investment, and is used in the production of collectible toys, models and figures ...
Transfer molding. Transfer molding (BrE: transfer moulding) is a manufacturing process in which casting material is forced into a mold. Transfer molding is different from compression molding in that the mold is enclosed [1] rather than open to the fill plunger resulting in higher dimensional tolerances and less environmental impact.

Vacuum Assisted Resin Transfer Molding (VARTM) or Vacuum Injected Molding (VIM) is a closed mold, out of autoclave (OOA) [1] composite manufacturing process. VARTM is a variation of Resin Transfer Molding (RTM) with its distinguishing characteristic being the replacement of the top portion of a mold tool with a vacuum bag and the use of a vacuum to assist in resin flow.

Shell molding, also known as shell-mold casting, [1] is an expendable mold casting process that uses resin covered sand to form the mold. As compared to sand casting, this process has better dimensional accuracy, a higher productivity rate, and lower labour requirements. It is used for small to medium parts that require high precision.

Procedure. It is a process using a rigid two-sided mould set that forms both surfaces of the panel. Usually, the mould is formed from aluminum or steel, but sometimes composite molds are used. The two sides fit together to make a mould cavity. The distinctive feature of resin transfer moulding is that the reinforcement materials are placed into ...
Rotational molding. A three-motor powered (tri-power) rotational-molding or spin-casting machine. Rotational molding (BrE: moulding) involves a heated mold which is filled with a charge or shot weight of the material. It is then slowly rotated (usually around two perpendicular axes), causing the softened material to disperse and stick to the ...
