A METHOD OF MAKING FRAME COMPONENTS FOR SPECTACLES AND A COMPONENT MADE BY THIS METHOD

摘要

A method is described for making frame components for spectacles, including: superimposing within a first mold, in the following order, at least a first film of plastic material, at least one semi-finished element pre-impregnated with resin, and at least a second film of plastic material; closing and heating the first mold, the temperature and pressure being applied and maintained until the resin is fully polymerized, in order to produce an intermediate component containing the semi-finished product); opening the first mold and extracting the intermediate component from the first mold. The method also includes: placing the intermediate component in a second mold; closing the second mold and forming a layer of polymer material on the intermediate component, resulting in mutual adhesion; opening the second mold and extracting an article produced by the molding step in the second mold and cutting the article to define the final profile of the component.

1. A method of making frame components for spectacles, the method comprising the following steps:
superimposing within a first mold (11), in the following order, at least a first film (12) of plastic material, at least one semi-finished element (13) pre-impregnated with resin, and at least a second film (14) of plastic material, closing and heating the first mold (11), the molding temperature and pressure being applied and maintained until the resin is fully polymerized, in order to produce an intermediate component (15) containing the semi-finished product (13), opening the first mold (11) and extracting the intermediate component (15) from the first mold (11), placing the intermediate component (15) in a second mold (16), closing the second mold (16) and forming a layer (17) of polymer material on the intermediate component (15), resulting in mutual adhesion, opening the second mold (16) and extracting an article (18) that has been produced by the molding step in the second mold (16), cutting the article (18) so as to define the final profile of the frame component.
