Method of manufacturing a composite component by a) providing an injection mold having at least one cavity to be opened and a tool dimension in the closing direction and a mold dimension at a right angle to the closing direction of the mold, and a cavity circumference which corresponds to the circumference of the cavity in the region of the mold dimensions and, and at least one secondary cavity, b) providing at least one hollow profile in the form of a hollow cylinder having i) the hollow profile circumferential dimension, the wall thickness, the outer diameter and the longitudinal axis, ii) at least one bend with angle, and iii) at least one perforation 2 along its longitudinal axis, and in areas of the hollow profile without bending iv) with a ratio of outer diameter to wall thickness in the range from 5:1 to 300:1, the outer diameter in the region of the contact surfaces is larger than the tool dimension by a range of 0.1 to 5% and is smaller by a range of from 0.1 to 5% than the tool dimension, and v) the data on the outer diameter refer to 90° in the direction to the longitudinal axis of the hollow profile, and vi) the hollow profile circumferential dimension UH = C * π corresponds to the cavity circumference of the at least one injection mold cavity in the closed state, and vii) the sealing surfaces of the mold in closed state with the hollow profile are named contact surfaces, c) inserting the at least one hollow profile into the at least one cavity of the injection mold, d) closing the at least one cavity of the injection mold, and pressing the hollow profile at its mold contact surfaces in the closing direction of the at least one cavity, e) injection of plastic into the interior of the hollow profile and simultaneous filling of the at least one secondary cavity via the at least one perforation 2 in the hollow profile, f) pressing out excess plastic material through at least one of the two lateral openings of the hollow profile by injection of gas or fluid or a combination of both, g) cooling the plastic melt introduced into the hollow profile and into the secondary cavity in e), and h) removing of the finished composite component from the injection mold and optionally removing of sprues, with the proviso that the data on mold dimension, on mold dimension and the cavity circumference in process step a) refer to regions of the of the injection mold in which areas of the hollow profile without bending are lying and the hollow profile is based on metal or on a composite. a) providing an injection mold having at least one cavity to
