摘要： A flexible mold has a mold body having a nanoimprinting microstructure and is gradually thickened from its periphery to the middle. Also, a resist spreading nanoimprinting method that integrates a soft mold into a dovetailed meal ring and then deforms it to form a point contact with a substrate before an imprinting process is followed and then convert a loading force into a specific distributed contact pressure for driving the resist flow by using an elastomer cushion pad with a pre-designed convex surface.

摘要： Disclosed herein are induction heating cells and methods of using these cells for processing. An induction heating cell may be used for processing (e.g., consolidating and/or curing a composite layup having a non-planar portion. The induction heating cell comprises a caul, configured to position over and conform to this non-planar portion. Furthermore, the cell comprises a mandrel, configured to position over the caul and force the caul again the surface of the feature. The CTE of the caul may be closer to the CTE of the composite layup than to the CTE of the mandrel. As such, the caul isolates the composite layup from the dimensional changes of the mandrel, driven by temperature fluctuations. At the same time, the caul may conform to the surface of the mandrel, which can be used to define the shape and transfer pressure to the non-planar portion.

摘要： Provided are induction heating cells including pressure bladders used for supporting dies and methods of using these induction heating cells. A pressure bladder may be disposed between a die and a bolster of the cell. Even when the bolster is deformed during operation of the cell, the pressure bladder continues to provide uniform support to the die thereby preserving integrity of the die and prevents its cracking or braking. As such, the cell may be operated at a higher processing pressure inside the cavity formed by the die without further strengthening the bolster. The bolster is allowed to deform without compromising the integrity of the die. The deformation of the bolster is compensated by the shape change of the pressure bladder. The number and/or position of the bladders in the cell may depend on the shape of processed parts.

摘要： A mold, particularly for injection molding, includes a shell defining a cavity delimiting a molding surface, a heat accumulator and inductor heater, configured to heat the heat accumulator. A receiving surface, which is a part of a surface of the shell other than the molding surface, is either exposed to or shielded from the heat of heat accumulator, to bring the entire molding surface to a predetermined temperature to inject the material into the cavity.

摘要： A system for inductively heating a workpiece may include an induction coil, at least one susceptor face sheet, and a current controller coupled. The induction coil may be configured to conduct an alternating current and generate a magnetic field in response to the alternating current. The susceptor face sheet may be configured to have a workpiece positioned therewith. The susceptor face sheet may be formed of a ferromagnetic alloy having a Curie temperature and being inductively heatable to an equilibrium temperature approaching the Curie temperature in response to the magnetic field. The current controller may be coupled to the induction coil and may be configured to adjust the alternating current in a manner causing a change in at least one heating parameter of the susceptor face sheet.

摘要： The present disclosure relates to a tool such as an injection molding tool or an embossing tool. A heating device including a stack of layers is provided for heating a tool surface. The stack may include a coil carrier layer with a number of wound coils for generating a magnetic field, and a conductive top layer, being adjacent to the tool surface currents are induced in the top layer to heat the surface. Efficient heating may be provided by solutions involving low resistivity layers that lead currents to the top layer without themselves developing heat to any greater extent. A conduction frame device can be provided beneath the top layer and around the perimeter thereof to provide reliable contact with a backing layer. A thermal resistance layer may placed between the intermediate layer and the top layer, and may comprise a heat resistive plastic material such as a polyimide.

At least one of the first and second dies includes a forming surface having a desired shape. The method further includes positioning a second susceptor made from a second susceptor material between the first and second dies such that the first susceptor is interposed between the second susceptor and the forming surface. Additionally, the method includes positioning a first bladder between the first and second dies such that the second susceptor is interposed between the first bladder and the first susceptor. Also, the method includes inflating the first bladder to concurrently deform the first susceptor and second susceptor into the desired shape.
