  • Publication number: 20230010076
    Abstract: A mould tool comprising: a first tool part defining a first mould cavity portion; a second tool part defining a second mould cavity portion; and, a cavity alignment system comprising: a temperature control system configured to control the temperature of a first zone of the first tool part to thereby effect thermal expansion and/or contraction in the first zone of the first tool part; a sensor configured to measure movement of a part of the first tool part in response to the said thermal expansion and/or contraction; and, a controller configured to control the temperature control system in response to feedback from the sensor to thereby control the position of the first mould cavity portion relative to the second mould cavity portion.

  • Patent number: 11123907
    Abstract: 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.
