<p>PURPOSE:To prevent an adhesive from being insufficient or being forced out by a method in which excessive thin wall-flanges are formed on the outer periphery of bonding surface, and then the adhesive is forced out across the contour of a product within the projected width of the flange and both members are mutually stuck, and further the flanges are cut off after the curing of the adhesive. CONSTITUTION:Thin wall-flanges 11a, 12a are formed on the outer periphery of the bonding end surface of an upper member 11 and a lower member 12. The bonding end surface 13b of the lower member 12 is coated with the thermosetting adhesive W of urethane group or epoxy group, and the bonding end surface 13a of the upper member 11 is superimposed thereon, and then the periphery of the bonded part 13 is pressed under heating with the clamp jig 15 provided with the heat source 16 such as steam or electric heat. The adhesive reaches the part between a pair of the flanges 11a and 12a across the bonded part 13, but it is not forced out from between the flanges. The flanges 11a, 12a are cut off by a press blade or water jet along a cut line L with the adhesive in inner part. Accordingly, since the surface to be cut off is smoothly cut, the molded object may be finished by soft sanding and coating.</p> |
