Designing of thermosetting plastic components for direct screwing
M. Sc. Maximilian Kramer, Prof. Dr.-Ing. Christian Hopmann, M. Sc. Johannes Hillemeyer, Prof. Dr.-Ing. Elmar Moritzer
Direct screwing is a very economically viable joining procedure for thermosetting plastic mouldings. However, users do not yet have at their disposal any guidelines to support them with regard to the configuration of the joint. In order to elaborate initial designing recommendations, investigations were conducted into the influences of the screw and tube geometries. Screws with cutting elements were easy to screw into thermosetting plastic moulding compounds. Moreover, it was possible to achieve screwing results in a reliable process using core hole and outside diameters slightly higher than those for the direct screwing of thermoplastics.
