Abstract
This invention relates to a die for the manufacture of products from expanded plastics material of the type which can be applied to conventional presses (not illustrated) commonly used for the moulding of expanded polystyrene or polypropylene. Die 1 substantially comprises two half-dies 2, 3 made of a material which is a good conductor of heat which can be joined together in such a way as to bound at least one cavity 4 within which a product 5 is moulded, having a substantially constant and small thickness S and the outer surface 2', 3' of which partly bounds a chamber 6, 7 within which steam V or a cooling liquid R flows. Cavity 4 has an opening 8 for the entry of the material M which is to be sintered and at least two microslots 10, 11 for the passage of steam V. <IMAGE>
