Device for forming or molding plastic elements on surfaces of a semi-finished product

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 in a locally defined manner along at least one axis relative to the semi-finished product by a manipulator;
• an arrangement adapted for injection molding disposed on a first leg the C-shaped bracket element, and a backing holder is disposed on a second leg of the C-shaped bracket element opposite the arrangement implemented for injection molding,
• wherein the device is adapted such that a semi-finished product can be disposed between the backing holder and the arrangement when an element is to be formed;
• and
• a first molding tool disposed in a direction toward a surface of the semi-finished product on which the element is to be formed, the first molding tool being open in a direction toward the corresponding surface of the semi-finished product and having a negative contour of the corresponding element,
• wherein the arrangement and/or the backing holder is displaceable against the corresponding surface of the semi-finished product, such that the open side of the first molding tool applies pressure to the corresponding surface of the semi-finished product and the backing holder contacts and applies pressure to an opposite surface of the semi-finished product when an element is produced by means of injection molding, and
• wherein the first molding tool and backing holder are then disposed opposite each other.
