PROCESSING METHOD OF TERMINAL PART OF MOLDING FOR MOTOR CAR

摘要

PURPOSE:To prevent a mating surface from generating a difference in level or a sink or flashes, by a method wherein a plastic molded product is processed in a stepped state beforehand so that a cross section of a terminal part of the plastic molded product is reduced to that of a main body part of the same by excluding the major part of an adhesion side to a car body. CONSTITUTION:A cross section of a stepped part 1a of a terminal of a main body part 1 of a molding of a plastic extrusion molded product is reduced by excluding an adhesive side 1c to a car body as compared with that of the main body part 1. Then the adhesive side 1c is flush with an adhesive side 1b without having a difference in level, and a pressure-sensitive tape 3 is stuck to the adhesive sides 1b, 1c beforehand by connecting with them. A mating surface 4 to be formed through joining between the stepped part 1a and a terminal part 2 of an injection molded material becomes a bent surface coincident with the external circumferential surface of the stepped part 1a. As the mating surface 4 is a bent surface, joining force is strengthened. Then neither the difference in level nor flashes are generated on an exposed part of the mating surface 4 and an external appearance of the surface is flat and beautiful due to elasticity of the pressure-sensitive tape 3.
