The present invention concerns a method for manufacturing a three-dimensional composite object (21a, 21b, 21c), especially a sports article, comprising the steps: (a.) preparing a rotatable casting mold (11); (b.) filling of a first material (14) into the casting mold (11); (c.) filling of a second material (15) into the casting mold (11), wherein at least one of the materials (14, 15) is a polymer material; (d.) moving of the casting mold (11); and (e.) adapting of at least one process parameter during the performance of one or more of the preceding steps, so that a homogeneous distribution of the second material (15) in the manufactured composite object (21a, 21b, 21c) is achieved.
