ABSTRACT:
For producing a vibration insulator for use in a motor vehicle or the like, a unique method is described which comprises (a) producing an inner unit which includes an inner cylindrical member of metal and a compounded rubber block disposed about the inner cylindrical member; (b) applying an adhesive to an inner surface of an outer cylindrical member of FRP, the adhesive being of a type which is cured and hardened when heated; (c) press-fitting the inner unit in the outer cylindrical member; (d) putting an electrode plate around the outer cylindrical member near the inner unit; and (e) applying a high frequency current to the electrode plate to induce a high frequency dielectric heating by which the adhesive and the compounded rubber block are heated, the high frequency current having a frequency lower than 100 MHz.
