Abstract: PURPOSE:To form an end part with a curved surface having an appearance continuous to the other part and make a cut surface inconspicuous, by a method wherein the inside of a synthetic resin molded product is softened and cutting is performed in a state where hardness of an external surface part becomes higher than that of the interior. CONSTITUTION:Resin in the vicinity of a cut part 17 of a molded product 2 inclusive of an external surface part 2a and the interior 2b is heated evenly by high-frequency induction heating at a temperature of the normal temperature or higher. As the external surface part 2a is cooled with air of the normal temperature, when the same is heated to such an extent as to soften the interior 2b, hardness of the external surface part 2a becomes higher than that of the interior 2b.

In this instance, as a tapered surface 12a is formed on a removal part 14 side of the cutting blade 12, the resin is extruded along the tapered surface 12a. When the cutting blade 12 is moved forward further under this state, the external surface part 2a of a cut part 17 becoming a molding 22 is deformed into a state of a curved surface while keeping an appearance where the same is continued to the other part and cut off under a state where an end part 23 in the state of the curved surface has been formed.
