2. Resin casting - Wikipedia

   en.wikipedia.org/wiki/Resin_casting

   The molds are commonly half-divided (like the hollowed chocolate Easter eggs with candy inside) and a release agent may be used to make removal of the hardened/set resin from the mold easier. The hardened resin casting is removed from the flexible mold and allowed to cool. A Baldwin 6-axle locomotive kit cast in resin in HO Scale

3. Molding (process) - Wikipedia

   en.wikipedia.org/wiki/Molding_(process)

   A mold or mould is a hollowed-out block that is filled with a liquid or pliable material such as plastic, glass, metal, or ceramic raw material. [2] The liquid hardens or sets inside the mold, adopting its shape. A mold is a counterpart to a cast. The very common bi-valve molding process uses two molds, one for each half of the object.

4. Shell molding - Wikipedia

   en.wikipedia.org/wiki/Shell_molding

   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. [2]

5. Vacuum assisted resin transfer molding - Wikipedia

   en.wikipedia.org/wiki/Vacuum_assisted_resin...

   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. [2]

6. Fiberglass molding - Wikipedia

   en.wikipedia.org/wiki/Fiberglass_molding

   The component-making process involves building up a component on the fiberglass mold. The mold is a negative image of the component to be made, so the fiberglass will be applied inside the mold, rather than around it. As in the mold-making process, release agent is first applied to the mold. Colored gelcoat is then applied.

7. Injection moulding - Wikipedia

   en.wikipedia.org/wiki/Injection_moulding

   Injection moulding (U.S. spelling: injection molding) is a manufacturing process for producing parts by injecting molten material into a mould, or mold. Injection moulding can be performed with a host of materials mainly including metals (for which the process is called die-casting ), glasses , elastomers , confections , and most commonly ...
