摘要 |
An apparatus for forming an object from a dose of plastics comprises a die arrangement provided with a cavity for receiving said dose and with at least two parts that are reciprocally movable for shaping an undercut portion of said object, at least one fluid for applying a clamping force so as to keep said at least two parts in contact; said at least one fluid is such as to increase discontinuously said clamping force from an initial force that is applicable when said dose is substantially contained in said cavity to a final force applicable when said at least two parts shape said undercut portion.
