AbstractA method of producing moulded plastics articles by a continuous moulding or extrusion operation which comprises providing in a screw machine a blend of filler and the precursors of a synthetic thermosetting material and operating the screw machine to (a) intimately mix the filler and the precursors or an uncured condensate thereof and plasticize the mixture and (b) convey the intimate mixture directly to a mould or extrusion head. The mixture is cured after being conveyed to the mould or extrusion head.
