  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. Acrylic resin - Wikipedia

    en.wikipedia.org/wiki/Acrylic_resin

    An acrylic resin is a thermoplastic or thermosetting plastic substance typically derived from acrylic acid, methacrylic acid and acrylate monomers such as butyl acrylate and methacrylate monomers such as methyl methacrylate. Thermoplastic acrylics designate a group of acrylic resins typically containing both a high molecular weight and a high ...

  4. Polyoxymethylene - Wikipedia

    en.wikipedia.org/wiki/Polyoxymethylene

    POM is a strong and hard plastic, about as strong as plastics can be, and therefore competes with e.g. epoxy resins and polycarbonates. The price of POM is about the same as that of epoxy. There are two main differences between POM and epoxy resins: epoxy is a two-component resin that can be cast, and adheres to everything it touches,

  5. 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.

  6. Plastisol - Wikipedia

    en.wikipedia.org/wiki/Plastisol

    It involves metal molds that are filled with liquid plastisol. When the open mold cavities are filled, the mold is spun on a high speed centrifuge to force the liquid vinyl into the fine details on the interior of the mold. Then the metal mold is placed into a heating solution, usually an industrial salt heated to about 204 °C (400 °F).

    en.wikipedia.org/wiki/Glossary_of_sculpting

    Casting is a method of producing one or more copies of a sculpture. Typically, the original sculpture is modeled as usual and covered with a molding material that sets hard when dry. The mold is then separated to release the original sculpture. Once the mold is reassembled, at its most simple the casting material is poured into the void and ...

  8. Bakelite - Wikipedia

    en.wikipedia.org/wiki/Bakelite

    The result is a hard plastic material. [27] Asbestos was gradually abandoned as filler because many countries banned the production of asbestos. [10]: 9 [28] Bakelite's molding process had a number of advantages. Bakelite resin could be provided either as powder or as preformed partially cured slugs, increasing the speed of the casting.

  9. Silicone - Wikipedia

    en.wikipedia.org/wiki/Silicone

    A silicone mold generally requires little or no mold-release or surface preparation, as most materials do not adhere to silicone. For experimental uses, ordinary one-part silicone can be used to make molds or to mold into shapes. If needed, common vegetable cooking oils or petroleum jelly can be used on mating surfaces as a mold-release agent. [24]
