In contrast to conventional injection molding in multicomponent technology, the injection molded parts produced using FOBOHA stack turning technology are processed at different levels within the turning system. Parts can therefore be molded at both levels in the same production stage, and the parts already finished ejected in the free station. The next rotation (2x180° or 4x90°) feeds the new pre-molding parts to the processing station that has been vacated. The advantages of this technology are obvious: highly complex parts can be manufactured on a single machine, the clamping force of the machine can be halved, the number of cavities can be doubled and production cycles are significantly shorter.
