A mold assembly for use in manufacturing parts includes a first and second mold halves and a mold temperature control system. The first mold half comprises at least a first mold cavity and a first coolant passage. The second mold half comprising at least a second mold cavity and a second coolant passage. The mold temperature control system is in fluid communication with the first and second coolant passages of the first and second mold half. The mold temperature control system comprises a fluid, a means to control the temperature of the fluid, and a pump to circulate the fluid through the mold temperature control system and the first and second coolant passages.

Systems and methods of curing a thermoset composite (TSC) to a target state of cure (SOC) are disclosed herein. The methods include heating the thermoset composite to greater than a threshold temperature. During the heating, the methods further include monitoring an actual temperature of the thermoset composite, determining a maximum temperature achieved by the thermoset composite, and determining an elapsed time that the actual temperature of the thermoset composite is greater than the threshold temperature. The methods further include ceasing the heating based, at least in part, on the maximum temperature of the TSC and the elapsed time. The systems include a heating assembly, a support mandrel, a thermoset composite, a temperature detector, and a controller programmed to perform the methods.

An imprint apparatus for forming a pattern of an imprint material on a substrate using a mold, includes a mold holding unit including an actuator for moving mold, a force sensor detecting force generated by actuator, a position sensor measuring a position of mold, and a controlling unit controlling operation of mold holding unit. The controlling unit controls mold holding unit according to either a force imprint profile or a position imprint profile. The force imprint profile is for controlling movement of mold based on force generated by actuator and detected by force sensor. The position imprint profile is for controlling movement of mold based on position of mold measured by position sensor. When pattern of imprint material is formed on substrate, either force imprint profile or position imprint profile is selectable.

A device for marking a work piece that is at least partially formed or reshaped through a thermal process is provided. The device includes a plurality of heating elements distributed laterally on a surface that is placed against the work piece and can be individually controlled for local heating of a work piece surface. Each of the heating elements includes a solid material with a surface structure and a heating structure. The surface structure includes at least one of a specifically or randomly varied topography. The surface structure can be at least partially heated through the heating structure.

An oven for heating a fibrous mat includes a first conveyor for conveying the mat in a forward direction, and a measurement system inside the mat, including a sensor mounted on the first conveyor and adapted to move, in a transverse direction of the mat, between a first retracted position inside the conveyor and a measurement position inside the mat under the effect of an activation system, the measurement system being such that the sensor is connected by a mechanical transmission system to a finger projecting on a lateral side of the first conveyor, and the activation system includes at least one contact surface located facing the lateral side of the conveyor and adapted to engage with the finger, when it moves in the forward direction in order to move the sensor from its retracted position to its measurement position by the mechanical transmission system.

An imprint apparatus includes: a movable housing unit; an ejection head provided in the housing unit and configured to eject an ejection material; a flexible member provided in the housing unit and separating the housing unit into a first storing space communicating with the ejection head and storing the ejection material and a second storing space storing hydraulic liquid; a first channel and a second channel communicating with the second storing space; a pressure control unit configured to control a pressure in the second storing space through the channels; and a bubble detection unit configured to detect bubbles in the channels.

An adhesive application device includes a coater and an air conditioning device. The coater includes a roll and a roll temperature control device. The roll has an elongated shape having an axis and outer surface and is rotatable around the axis. The roll holds thermosetting adhesive on the outer surface and applies the thermosetting adhesive to an application surface of a sheet member with the first roll being rotated and contacted with the sheet member. The roll temperature control device is disposed adjacent to the roll and configured to lower temperature of the outer surface of the roll to control viscosity of the thermosetting adhesive held by the roll to be appropriate application viscosity that is appropriate for application to the sheet member. The air conditioning device is configured to adjust temperature and humidity of air in a space near the coater.

An imprint apparatus for performing an imprint process of forming a pattern of an imprint material on a substrate using a mold is disclosed. The imprint apparatus includes an adjustment unit configured to adjust a shape of the mold and a control unit configured to control the imprint process. The control unit obtains information indicating a tendency concerning a change of the shape of the mold corresponding to a use count of the mold used for the imprint process and controls the adjustment unit to correct the shape of the mold in accordance with the obtained information and a present use count of the mold. The control unit also controls the imprint apparatus to perform the imprint process after the shape of the mold has been corrected by the adjustment unit.

A method of imprinting a substrate (180), comprising affixing a flexible stamp (104) carrying an imprinting pattern (106) to a first carrier (102) comprising an array of apertures (112) which, by gas pressure, either pull the flexible stamp towards the first carrier or push it away; pushing it to a second carrier (170) carrying a substrate (180) with a resist layer (182), leaving a gap (190) for creating a controllable contact area between the flexible stamp and the substrate and space (196) between the first carrier and the flexible stamp; progressively pushing areas of the flexible stamp into the resist layer to imprint it; developing the resist layer; and progressively releasing the flexible stamp by applying suction through successive apertures whilst controlling the inward flow of gas to the space (196) through the apertures that are not yet under suction in order to maintain the space (196) there above ambient but below a pre-determined maximum pressure.
