HOT METAL WORKING

Having already discussed metal working techniques and the differences between hot and cold working, this week’s #FocusOn will look deeper into the types of hot working, including forging and casting.
Forging gets its name from the term “forge“, the place where the metal to be worked is heated, while forging is the process of heating the metal to a very high temperature to make it as malleable as possible. The metal is then struck with a mallet until it takes on its desired shape. This is a very ancient technique, and metal that is worked in this way today is very expensive.

Casting metal is a hot working technique in which the hot metal is placed in a mould, with another mould placed on top, known as the counter mould. The moulds are then clamped together with significant pressure. Immediately after, the piece is cut into its final shape, and burrs and dull angles are removed.
