PROBLEM TO BE SOLVED: To make it possible to heat the fusion-bonding part of a molding without contact, to increase the life of a heating plate and to eliminate the necessity of replacement by heating the plate to a high temperature. SOLUTION: A heating plate 1 made of stainless steel is heated by a heating coil 2 to a predetermined temperature (e.g. 600 deg.C). Resin moldings 5, 6 are respectively mounted at lower and upper holding members 3, 4. The plate 1 is moved from a heating stage to a fusion-bonding stage, and the fusion-bonding part of the molding is heated. After it is waited until the fusion-bonding part of the molding is sufficiently melted, the plate is reset to the original heating stage, the upper member 4 is lowered, the molding 6 is pressed to the molding 5 to be fusion-bonded. |
