Abstract
A method for manufacturing three-dimensional products with at least one inclined product portion made of a fiber-containing material using at least one forming tool and a forming tool are described. Vibrations are introduced via a device and this results in an improved compression of fiber-containing material in the region of inclined portions.
Claims11
A method for manufacturing three-dimensional products with at least one inclined product portion made of fibers, using at least one forming tool, wherein the at least one forming tool has at least one first tool component with at least one cavity and at least one second tool component with at least one mold part corresponding to the at least one cavity, wherein the at least one mold part and the at least one cavity are movable relative to one another to form a mold cavity between corresponding surfaces of the at least one cavity and the at least one mold part, the method comprising:
- introducing the fibers into the at least one cavity of the at least one first tool component;
- closing the at least one forming tool by relative displacement of the at least one first tool component and the at least one second tool component;
- pressing the fibers within the mold cavity;
- and
- laterally moving the at least one first tool component and/or the at least one second tool component relative to a pressing direction during the pressing to introduce vibrations in the fibers.
A forming tool for manufacturing three-dimensional products with at least one inclined product portion from fibers, comprising at least one first tool component with at least one cavity and at least one second tool component with at least one mold part corresponding to the at least one cavity, wherein the at least one mold part and the at least one cavity operable to be moved relative to one another to form a mold cavity between corresponding surfaces of the at least one cavity and the at least one mold part, and are operable to be pressed to press the fibers that is configured to be inserted into the mold cavity, the forming tool further comprising a device for laterally moving the at least one first tool component and/or the at least one second tool component perpendicular to a pressing direction during the pressing to introduce vibrations in the fibers.
