## 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.

## Claims

### Claim 1

A mould tool comprising:
a first part defining a first area of a mould profile;
an actuated part defining a second, adjacent area 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;
wherein the actuated part comprises a temperature control apparatus configured to control a temperature of the actuated part to influence a clearance between the first part and the actuated part by thermal expansion and/or contraction of the actuated part.

### Claim 2 (depends on 1)

A mould tool according to claim 1, wherein the temperature control apparatus is configured to alternately heat and cool the actuated part.

### Claim 3 (depends on 1)

A mould tool according to claim 1, wherein the temperature control apparatus is heated and/or cooled by a heated and/or cooled fluid.

### Claim 4

(canceled)

### Claim 5 (depends on 3)

A mould tool according to claim 3, wherein the temperature control apparatus comprises a fluid channel having a heater therein, which fluid channel is configured to direct fluid into the actuated part such that heating of the actuated part is carried out by heating fluid passing the heater.

### Claim 6 (depends on 5)

A mould tool according to claim 5, wherein the temperature control apparatus comprises a controller configured to switch between a heating mode in which the heater is activated, and a cooling mode in which the heater is inactive, in which fluid flows into the actuated part in both the heating and cooling modes.

### Claim 7 (depends on 6)

A mould tool according to claim 6, wherein the controller is configured to increase the flow rate of the fluid in the cooling mode compared to the heating mode.

### Claim 8 (depends on 6)

A mould tool according to claim 6, further comprising a temperature sensor configured to measure the temperature of the actuated part and feed back a temperature signal to the controller.

### Claim 12 (depends on 6)

A mould tool according to claim 6, further comprising a strain gauge configured to measure a strain of the actuated part and feed back a strain signal to the controller.

### Claim 13 (depends on 6)

A mould tool according to claim 6, wherein the mould tool is configured such that the mould face is divided into a plurality of temperature controlled zones, each temperature controlled zone comprising an independently operable temperature control apparatus.

### Claim 14 (depends on 13)

A mould tool according to claim 13, wherein the temperature control apparatuses of the temperature controlled zones share a common controller with the temperature control apparatus of the actuated part.

### Claim 15

(canceled)

### Claim 16 (depends on 1)

A mould tool according to claim 1, further comprising a tool controller configured to control a mould tool cycle, which tool controller is configured to:
firstly demand that the actuated part is moved to the moulding position;
secondly demand that the actuated part is heated by the temperature control apparatus;
thirdly demand that the actuated part is cooled by the temperature control apparatus; and,
fourthly demand that the actuated part is moved to the actuated position.

### Claim 17 (depends on 1)

A mould tool according to claim 1, wherein the first part of the mould tool comprises a collar extending therefrom to surround the actuated part from movement thereof.

### Claim 18 (depends on 17)

A mould tool according to claim 17 wherein the collar surrounds the actuated part and extends to an exhaust layer of the mould tool.

### Claim 19

A method of manufacturing a moulded component comprising the steps of:
providing a mould tool having a first part defining a first area, and an actuated part defining a second, adjacent area;
moving the actuated part to a moulding position where the first and second areas form a continuous mould profile;
independently heating the actuated part to close a gap between the actuated part and the first part;
curing a moulded component in the mould tool;
independently cooling the actuated part to open a gap between the actuated part and the first part; and,
moving the actuated part to facilitate removal of the moulded component from the mould tool.

### Claim 20 (depends on 19)

A method of manufacturing a moulded component according to claim 19, wherein the actuated part is heated and/or cooled by fluid.

### Claim 21

(canceled)

### Claim 22 (depends on 20)

A method of manufacturing a moulded component according to claim 20, comprising the step of:
providing a temperature control apparatus having a fluid channel with a heater therein, which fluid channel is configured to direct fluid into the actuated part;
wherein the step of heating comprises the step of passing fluid over the activated heater.

### Claim 23 (depends on 20)

A method of manufacturing a moulded component according to claim 20, wherein the fluid flow rate is higher during cooling.

### Claim 24

(canceled)

### Claim 25

(canceled)
