PURPOSE:To increase heat resistive adhesion strength by a method in which the contact end surface of normal part is coated, as an adhesive, with the solution of specified composition in which PVC is dissolved into the good solvent therefor, and a deformed part is integrally molded. CONSTITUTION:The contact end surface 1a of normal part 1 is coated with the solution in which 0.5-20wt. part PVC is dissolved into 100wt. part good solvent (methylethylketone, tetrahydrofuran, dimethylformamide, etc.), and thus a PVC coat is formed. Then, said materials are set in a mold 3, and a deformed part 2 is molded and simultaneously is made integrally therewith, injecting PVC into a cavity 4. Obtained PVC product such as side braid and glass run, etc. may be sufficiently used even at a severaly hot place. |
