Abstract: An arrangement and method for manufacturing a composite part includes a mold, a composite material including fiber material and matrix material on a forming surface of the mold. To provide a simple and cheap technology for forming and optionally curing the component at the mold, the method includes providing a pressing tool made of semi-crystalline thermoplastic material in an amorphous state on the forming surface of the mold, forming the pressing tool by applying a pressure, that can be by expanding a hollow mandrel, and pressing the pressing tool against the mold, conducting crystallization of the pressing tool material by increasing the temperature of the pressing tool so material of the pressing tool is crystallized. Afterwards, the composite part may be hardened, such as by curing the composite part between the mold and the crystallized tube mandrel.
