ABSTRACT:
Thermoplastic articles such as fenders, of large cross-sectional dimensions, may be made by extrusion without shrinkage voids by extruding a first stream of theremoplastic as a hollow profile, and extruding a second stream of molten thermoplastic by a second extruder and forcing same under pressure into the hollow profile to till the voids of shrink-age on cooling.
