  • Publication number: 20090212458
    Abstract: A method and apparatus for forming an article from mouldable material is disclosed. A mouldable material, such as a thermoplastic is heated until it is molten and is fed into an injector (900) of an injection moulding apparatus. A liquid, such as water, is introduced (930) into the stream of molten plastic. Because the molten plastic is at a temperature above the boiling point of the water, the water will boil and will expand the plastic material forming a honeycomb structure of bubbles that remains once the material has cooled.
