<p>The flowing plastic material, comprising several constituents, is combined by dosing apparatus immediately before entering the machine. Preferably, the dosing apparatus comprises shafts with positive displacement wheels, capable of adjustment to different supply ratios. Accurate proportioning of materials for high quality injection moulded or extruded products, especially the combining of raw material (e.g. PVC) with lubricants, stabilisers, fillers and colouring matter is possible using such machinery.</p> |
