    • 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.
    • 本发明涉及一种生产热塑性锅炉(26)的方法。 该方法包括以下步骤:提供穿孔加强件(10)并将穿孔加强件定位在模具(14)中,穿孔加强件的外表面和模具的内表面限定模制腔(18)。 将热塑性材料放置在模具内部,然后通过旋转模制被加热和模制。 首先,在模制腔内模制外部热塑性层(20),之后在穿孔加强件的内表面上模制内部热塑性层(22)。 本发明延伸到通过该方法制造的热塑性模制产品,特别是用于加热水的锅炉。
