2. RTV silicone - Wikipedia

   en.wikipedia.org/wiki/RTV_silicone

   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.

3. Injection molding of liquid silicone rubber - Wikipedia

   en.wikipedia.org/wiki/Injection_molding_of...

   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 required.

4. Spin casting - Wikipedia

   en.wikipedia.org/wiki/Spin_casting

   To ensure replicable casting cycles of accurate reproductions with a high quality finish, the spin casting process requires casting materials with the following qualities, for the following reasons: Low temperature operation - Spin casting is a low temperature process, as overexposure to high temperatures causes the rubber mold to degrade.

5. Silicone - Wikipedia

   en.wikipedia.org/wiki/Silicone

   Two-part silicone systems are used as rubber molds to cast resins, foams, rubber, and low-temperature alloys. 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.

6. Casting - Wikipedia

   en.wikipedia.org/wiki/Casting

   Casting is a manufacturing process in which a liquid material is usually poured into a mold, which contains a hollow cavity of the desired shape, and then allowed to solidify. The solidified part is also known as a casting, which is ejected or broken out of the mold to complete the process.

7. Rotational molding - Wikipedia

   en.wikipedia.org/wiki/Rotational_molding

   Normally all rotation molding systems include molds, oven, cooling chamber and mold spindles. The molds are used to create the part, and are typically made of aluminium. The quality and finish of the product is directly related to the quality of the mold being used. The oven is used to heat the part while also rotating the part to form it as ...
