Abstract
Cured thermoset plastics artefacts, (including extrusions) are made directly from a non-homogeneous blend of a filler and a solid particulate thermosetting material, by use of a screw injection moulding machine (or screw extruder) which is operated to cause the non-homogeneous blend to plasticize or flux so that a homogeneous intimate mixture of the filler and the thermosetting material is formed in the barrel of the machine. Thus, the moulding (or extrusion) sequence includes the provision or formation of the non-homogeneous blend in the barrel.
