<p>The invention concerns a method of producing a thermoplastic boiler (26). The method includes the steps of providing a perforated reinforcing (10) and locating the perforated reinforcing in a mould (14), an outer surface of the perforated reinforcing and an inner surface of the mould defining a moulding cavity (18). A thermoplastic material is placed inside the mould whereafter it is heated and moulded by way of rotational moulding. First an outer thermoplastic layer (20) is moulded inside the moulding cavity whereafter an inner thermoplastic layer (22) is moulded on an inner surface of the perforated reinforcing. The invention extends to a thermoplastic moulded product produced by the method, in particular a boiler for heating water.</p> |
