Abstract

PURPOSE:To coat the outer surface of the product highly efficiently by a method wherein the product such as the water tank, bathtub or the like is arranged as a male mold so as to oppose to the cavity section of a female mold for forming and thermoplastic resin particles are expanded in a space between both of them to form an expanded body 1ayer on the outer surface of the product. CONSTITUTION:In case the expanded body layer as a condensation preventing material or a heat insulating material is coated on the surface of the product such as the water tank, bathtub or the like, the water tank 2 is put on a bearer 11 to cover it and the lower end surface 31 of the female mole 20 for forming is arranged so as to abut against the flange section 4 of the water tank 2 and thus the space 32 is formed between the outer surface of the water tank 2 and the female mold 20. Subsequently, the expandable thermoplastic resin particles such as the same of polyethylene, polystyrene, polypropylene or the like are supplied into the space 32 through a supplying port 27 and steam in a steam chamber 21 is injected into the space 32 through steam ports 25, thereby expanding the resin particles 33 to form the expanded body layer and simultaneously fusion-welding the expanded body layer to the water tank integrally.
