<p>A method and machine for the utilisation of scrap plastics material involves the use of a granulator (15), to which scrap plastics material is delivered, to produce particles having a size of no greater than about 10mm, which is then heated in a oven to an extent sufficient to cause part at least of the surface of the granules to become molten, but insufficient to cause substantial melting of the granules. The granules are then compressed together into the form of a desired article, which may subsequently be subjected to a finishing or machining operation. The partly heated granules are compressed conveniently in a mould such as a continuous extrusion mould. The material may be processed by an injection moulding process.</p> |
