A rotational moulding device comprising at least one chassis (1), a first frame (2) hinged to said chassis about a substantially horizontal axis (3), a second frame (4) hinged to the first frame according to a substantially horizontal axis (6) orthogonal to the hinge axis of the first frame, means for driving the first frame and the second frame about the respective axes of same, at least one detachable mould (5) suitable for being rigidly connected to the second frame, said mould comprising two half-cavities (5a, 5b) suitable for being rigidly connected to each other in a sealed and detachable manner, and means for heating said mould; said device is remarkable in that each half-cavity of said mould is made from steel of which the thickness is less than or equal to 4 mm and in that the outer wall of each half-cavity comprises a heating cable (14) of which the diameter is less than or equal to 4 mm, in a configuration cabal of obtaining a temperature inside the mould of up to 600°C. |
