Method of assembling, by adhesive bonding, components made of expanded polystyrene in order to form a mould cavity serving as a pattern consumed during metal casting (moulding) of the consumable-pattern type, in which method an acrylic adhesive in aqueous suspension or emulsion is sprayed onto the parts to be adhesive coated, covering the entire area of the joint with a weight content per unit area not exceeding 15 g/m<2>, the adhesive is dried by blowing hot air over the surface and the components forming the mould cavity are joined by contact. |
