1. A device for forming or molding elements on one or more surfaces of a semi-finished product, the device comprising:
a C-shaped bracket element configured to be positioned along at least one axis relative to the semi-finished product by a manipulator,
wherein the C-shaped bracket element has a C-shaped holding bracket and a C-shaped positioning bracket, and
wherein the C-shaped holding bracket is disposed outboard of or parallel to the C-shaped positioning bracket;
an arrangement adapted for injection molding disposed on a first leg of the C-shaped holding bracket;
a backing holder disposed on a second leg of the C-shaped holding bracket opposite the arrangement and adapted for injection molding,
wherein the semi-finished product is disposed between the backing holder and the arrangement when an element is to be formed or molded on a surface of the semi-finished product; and
a first molding tool disposed in a direction toward the surface of the semi-finished product on which the element is to be formed or molded, the first molding tool having an opening in a direction toward the surface of the semi-finished product and having a negative contour in the shape of the element,
wherein the first molding tool and backing holder are disposed on opposite sides of the semi-finished product,
wherein the arrangement and/or the backing holder is displaceable against the surface of the semi-finished product, such that the opening of the first molding tool applies pressure to the surface of the semi-finished product and the backing holder contacts and applies pressure to an opposite surface of the semi-finished product while the element is formed or molded,
wherein the arrangement comprises a plasticization unit for metered feeding of plasticized material into the first molding tool, and a feeder for feeding element material in granulate form to the plasticization unit, and
wherein the first molding tool defines at least one channel fluidly connecting the plasticization unit and the negative contour, the at least one channel configured to transport the plasticized material from the plasticization unit into the negative contour.
