METHOD FOR MANUFACTURING STOPPERS

摘要

A method for manufacturing stoppers (1), comprising the operations of preparing a mold (2), inside which at least one cavity (3) is formed which is connected to the outside by means of a front opening (4); associating an injector with the mold (2) at the front opening (4). The method also includes an injection of plastic material into a first portion (31) of the cavity (3) to obtain a first contoured body (6) and a second injection of plastic material into a second portion (32) of the cavity (3) to obtain a second contoured body (7) which mates by spontaneous adhesion with the first contoured bod (6).
