The cast restricts ankle movement while allowing knee mobility. In some cases, a toe plate is added to a short leg cast to provide additional protection for toe injuries or fractures. The toe plate is an extension of the cast that covers the toes, shielding them from external forces and reducing the risk of further injury during recovery.
Total contact casting (TCC) is a specially designed cast designed to take weight off of the foot (off-loading) in patients with diabetic foot ulcers (DFUs). Reducing pressure on the wound by taking weight off the foot has proven to be very effective in DFU treatment.
The metal must be molten prior to introduction into the mold. It is necessary for a spin casting furnace to have a temperature controller, as there is an optimal range for each metal. For example, a particular zinc alloy is typically cast between 413 and 427 °C (775 and 801 °F), whereas it actually melts much lower around 260 °C (500 °F).
The dried mold is then assembled, preheated, and the metal poured. Finally, after the metal has solidified, the plaster is broken from the cast part. The mold is usually damaged from the metal so reusing is usually not done. Discarded plaster can be recycled by grinding but care must be used since silica dust causes permanent lung damage. [1] [2]
Casting is most often used for making complex shapes that would be otherwise difficult or uneconomical to make by other methods. Heavy equipment like machine tool beds, ships' propellers, etc. can be cast easily in the required size, rather than fabricating by joining several small pieces. [1] Casting is a 7,000-year-old process.

Conventional bloom casters cast sections above 200×200 mm. The bloom length can vary from 4 to 10 m; Billet casters cast smaller section sizes, such as below 200 mm square, with lengths up to 12 m long. Cast speeds can reach up to 4 m/minute. Rounds: either 500 mm or 140 mm in diameter
