Physical foaming a footwear component with a single-phase solution of a polymeric composition and a supercritical fluid is provided. The method include temperature conditioning a mold and then engaging the mold with a robot that conveys the mold to a press. At the press a gas counter pressure is applied to a cavity of the mold before injecting a single-phase solution of a polymeric composition and a supercritical fluid into the cavity of the mold. The process continues with releasing the gas counter pressure from the cavity of the mold and then removing the footwear component from the cavity of the mold. The parameters of the method are configured for the formation of the footwear component in an automated manner.

A mould tool (100) has a first part (102) defining a first area (114) of a mould profile, an actuated part (130) defining a second, adjacent area (132) of the mould profile, which actuated part is configured to move from a moulding position to an actuated position at the end of each mould cycle to facilitate removal of a moulded component. The actuated part (130) comprises a temperature control apparatus (108) configured to control the temperature of the actuated part to influence a clearance (C) between the first part and the actuated part by thermal expansion and/or contraction of the actuated part.
