===Tooling===
The mould and mould inserts are referred to as "tooling". The mould/tooling can be built from different materials. Tooling materials include [[aluminium]], [[carbon fibre]], [[invar]], [[nickel]], reinforced [[silicone rubber]] and steel. The tooling material selection is normally based on, but not limited to, the [[coefficient of thermal expansion]], expected number of cycles, end item tolerance, desired or expected surface condition, cure method, [[glass transition temperature]] of the material being moulded, moulding method, matrix, cost, and other various considerations.
