<p>Apparatus for rotational moulding comprises a feed hopper (10) pressurised by a compressed air supply (20) from which moulding powder may be fed under pressure via a line (12) to a mould (4). The feed line includes rotatable joints (14 and 16) which enables the mould to be rotated about two perpendicular axes, while material to be moulded is being fed to the mould. The apparatus and associated method reduce risk to operatives from inhalation of material, facilitate production of multilayer products and enable faster cycle times.</p> |
