Systems and methods for producing a preform for a composite member. An exemplary method includes preparing a lay-up of reinforcement layers and thermoplastic interlayers, and transferring the lay-up to a preform tool. The method further includes inducing heat in the preform tool to a transition-temperature range that causes the thermoplastic interlayers to become tacky or viscous, and applying pressure to the lay-up with the preform tool to shape the lay-up into the preform.

The document relates to a device for producing a 3D molded product from a pulp slurry, comprising a pair of cooperating press tools, each having a respective product face. The press tools are movable relative each other between a closed press position, wherein the product faces are sufficiently close to press the pulp product there between, and an open transfer position, wherein the pulp product can be removed from the product face of one of the press tools. At least one of the product faces is porous. The device further comprises a radiation heater, which is adapted to radiate heat towards the product face of the porous press tool, when the porous press tool is in its open position.

A mold to shape a material having a polymer matrix. The mold includes a first and a second die having molding surfaces. The molding surfaces delimit a molding cavity configured to shape the material when the first and the second dies are brought in contact with each other and the mold is closed. The heating plates include a ferromagnetic material configured to be heated by induction, and to transfer heat from a heat transfer surface of the heating plate to a receiving surface of the dies, other than the molding surfaces. The heating plates include heating and cooling channels. The heating channels of the heating plates have an inductor. The cooling channels of the heating plates are configured to circulate a heat transfer fluid.
