  • Pressing tool with optimized resin flow
    Patent number: 10507623
    Abstract: A pressing tool is provided for producing fiber composite components, including a first tool part and a second tool part moveable relative to the first tool part. In the closed state of the pressing tool, the two tool parts form a shaping cavity for accommodating a fiber semi-finished product to be shaped and each have a tool surface delimiting the cavity. In addition, at least one of the tool surfaces has at least two adjacent flat sections inclined toward each other which are connected to each other by way of a curved transition section. The curved transition section has at least one groove-shaped recess facing the cavity.
