   Occidental Réplicas (Portugal) - Brand of a plastic plant for home products, that started to build models that were used or in use by the Portuguese armed forces current and past, age of discovery ships naus caravelles etc, spitfire Fiat G-91 fighters and T-6 Texan, and so on, sold several sprues molds to Revell and Italeri for several kits.

3. Resin casting - Wikipedia

   en.wikipedia.org/wiki/Resin_casting

   Specialist equipment can enable closed molds to be filled whilst under vacuum, a process known as resin vacuum casting, where air and gas bubbles are completely removed from the cast part. Pressure and/or centrifugal force can be used to help push the liquid resin into all details of the mold. The mold can also be vibrated to expel bubbles.

4. Duramold - Wikipedia

   en.wikipedia.org/wiki/Duramold

   Birch or poplar plies are impregnated with phenolic resin and laminated together in a mold under heat (280 °F, 138 °C) and pressure for use as a lightweight structural material. [1] Similar to plywood , Duramold and other lightweight composite materials like the similar Haskelite were considered critical during periods of material shortage in ...

5. Aurora Plastics Corporation - Wikipedia

   en.wikipedia.org/wiki/Aurora_Plastics_Corporation

   Aurora Plastics Corporation was founded in March 1950 by engineer Joseph E. Giammarino (1916–1992) and businessman Abe Shikes (1908–1986) in Brooklyn, New York (moving to West Hempstead, Long Island in 1954), as a contract manufacturer of injection molded plastics.

6. Resin transfer moulding - Wikipedia

   en.wikipedia.org/wiki/Resin_transfer_moulding

   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 this cavity, and before the introduction of the matrix material, the mould set is closed.

7. Plastic extrusion - Wikipedia

   en.wikipedia.org/wiki/Plastic_extrusion

   A common post-extrusion process for plastic sheet stock is thermoforming, where the sheet is heated until soft (plastic), and formed via a mold into a new shape. When vacuum is used, this is often described as vacuum forming. Orientation (i.e. ability/ available density of the sheet to be drawn to the mold which can vary in depths from 1 to 36 ...

8. Foundry - Wikipedia

   en.wikipedia.org/wiki/Foundry

   The pattern is made of wax, wood, plastic, or metal. The molds are constructed by several different processes dependent upon the type of foundry, metal to be poured, quantity of parts to be produced, size of the casting, and complexity of the casting. These mold processes include: Sand casting – Green or resin bonded sand mold.

9. Injection moulding - Wikipedia

   en.wikipedia.org/wiki/Injection_moulding

   The exact amount of shrinkage is a function of the resin being used, and can be relatively predictable. [4] To prevent spikes in pressure, the process normally uses a transfer position corresponding to a 95–98% full cavity where the screw shifts from a constant velocity to a constant pressure control. Often injection times are well under 1 ...
