Injection molding of liquid silicone rubber (LSR) is a process to produce pliable, durable parts in high volume. Liquid silicone rubber is a high purity platinum cured silicone with low compression set, good stability and ability to resist extreme temperatures of heat and cold ideally suitable for production of parts, where high quality is ...
The spin casting process typically uses vulcanized silicone or organic rubber as the mold-making substrate. Vulcanization is an integral step that occurs halfway through the mold-making process. Prior to vulcanization, the mold rubber is a soft and malleable solid-like fluid, in many ways very similar to Silly Putty. Because of the clay-like ...
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.
Silicones also exhibit good chemical resistance and high-temperature resistance (205 °C, 400 °F and higher). For this reason, silicone molds are suitable for casting low-melt metals and alloys (e.g. zinc, tin, pewter, and Wood's metal). RTV silicone rubbers are, however, generally expensive – especially platinum-cure.
Their work with pewter allowed Ral Partha's mold-makers to develop the technical expertise necessary to transition to non-lead alloys in the early 1990s. Robert N. Charrette joined Ral Partha in 1984 and contributed to Meier's The Hoplites , 1200 A.D. , and CS/02-xxx Collector Series lines. [ 35 ]
Filter for nozzle with a plastic toy next to it. Injection moulding is used to create many things such as wire spools, packaging, bottle caps, automotive parts and components, toys, pocket combs, some musical instruments (and parts of them), one-piece chairs and small tables, storage containers, mechanical parts (including gears), and most other plastic products available today.

The master is measured with a probe linked to a pantograph that reduces the measurements to the correct size and drives the cutter that makes the moulds. A more recent development is the use of digital 3D models made by computer artists.
