In a method of producing a resin frame member for a fuel cell, a processing die is used. The method includes a processing step of moving an upper die toward a lower die to thereby form an inclined surface on each of side parts of a resin film. In the processing step, shearing is performed while maintaining a predetermined clearance between the lower processing section and the upper processing section and in a state where each of the side parts is at least partially positioned at a cutout so that each of the side parts is inclined downward toward the inside. The cutout is formed by cutting off an edge part of a placement surface that is positioned on the lower processing section side.

The disclosure relates to a method for material processing of a two-dimensional sheet like material. The method comprises: obtaining information related to a desired design of a three dimensional object; obtaining information related to material characteristics of the sheet like material; defining a primary surface and a secondary surface of the desired design; and defining a geometrical relationship between said primary surface and secondary surface, wherein the secondary surface is a reflection of the primary surface in a two dimensional plane, and wherein when said primary surface is concave said secondary surface is convex, or when said primary surface is convex said secondary surface is concave; and providing a digital instruction for a fully developed spreading and subsequent folding of a two dimensional sheet into the obtained desired design, wherein said digital instruction is based on the defined primary and secondary surfaces, respectively, and said obtained material characteristics.

In manufacturing an electrothermal heater mat, there is provided a preform which comprises a laminated stack of dielectric layers which are made of thermoplastic material and include a central layer or group of layers which include(s) reinforcement and first and second outer groups of layers which do not include reinforcement. The preform includes a heater element and the preform has a first configuration. The preform is then heated to a temperature (e.g. 180° C.) between the glass-transition temperature of the thermoplastic material and the melting point of the thermoplastic material, and the heated preform is formed into a second configuration which is different to the first configuration so as to produce the heater mat.
