| 摘要 |
The invention relates to a method for manufacturing a molded article from a first rubber polymer, which molded article comprises an insert from a second rubber polymer. The method comprises the steps of (A) providing an at least partially vulcanized article from the first rubber polymer, the article having a recess that extends in a depth direction and in transverse directions perpendicular to the depth direction, for accommodating the insert; (B) providing an at least partially vulcanized insert from the second rubber polymer, the insert having a shape such that it can be accommodated in the recess; (C) arranging an unvulcanized object from a third rubber polymer in the recess to partly fill the recess; (C) arranging the at least partly vulcanized insert in the recess to obtain an assembly; and (D) vulcanizing the assembly under pressure. The method yields a molded article having an optically sharp interface between the first rubber polymer and the insert. |
