ABSTRACT:
By means of a piston-like movement, solid fillings, for example of mineral fibers or steel wool, introduced in the pressureless zone of a screw are incorporated in the molten plastic and the resulting mixture formed in a mold. The finished molding contains numerous fillings greater than 2 mm in length which inter alia contribute significantly towards improving its strength.
