Body casts, also known as full-body casts are devices designed to immobilize the trunk of the body, sometimes extending to the neck, head, or extremities. They are less commonly used today due to advances in less restrictive bracing systems and surgical techniques but remain crucial in specific cases where maximum immobilization is essential.
Like sand casting, plaster mold casting is an expendable mold process, however it can only be used with non-ferrous materials. It is used for castings as small as 30 g (1 oz) to as large as 7–10 kg (15–22 lb). Generally, the form takes less than a week to prepare. Production rates of 1–10 units/hr can be achieved with plaster molds. [1] [2]
Plaster and other chemical curing materials, such as concrete and plastic resin, may be cast using single-use waste molds as noted above, multiple-use 'piece' molds, or molds made of small rigid pieces or of flexible material such as latex rubber (which is in turn supported by an exterior mold). When casting plaster or concrete, the material ...
Podiatrists mold custom orthotics to address patients' foot malformations. There are multiple means developed to create the basis for the molds, including plaster casts, foam box impressions, and three-dimensional computer imaging. The molds are used to create custom inserts that tend to be firm, flexible, and relatively soft.
Mold application. Mould material is applied to the surface of the model's body. The mould material is usually applied as a thick liquid that takes the shape of the body. Body parts may also be dunked into containers of mold media (except plaster). Mold curing and reinforcement. The applied mold material cures to a more rigid and solid state.

It is a combination of plaster mold casting and investment casting. [2] [3] There are two types of ceramic mold casting: the Shaw process and the Unicast process. [4] These casting processes are commonly used to make tooling, especially drop forging dies, but also injection molding dies, die casting dies, glass molds, stamping dies, and ...
This process is now known as the full mold process. [9] [10] In 1964, M.C. Flemmings used unbonded sand for the process. The first North American foundry to use evaporative-pattern casting was the Robinson Foundry at Alexander City, Alabama.
