11597170 · 2023-03-07 · ·

Provided is a method for manufacturing a fiber reinforced resin molded article capable of distributing the pressure without concentration on the vicinity of the resin inlet and so preventing the deformation of a preform, and such a manufacturing device thereof. The method lowers a lower core as a moving core in a lower mold (first mold) (away from a preform) to let resin flow toward the lower mold (first mold). This distributes the pressure concentrated in the vicinity of the resin inlet and prevents deformation of the preform.

Method for injection molding plus power lens elements

A method for injection molding of a plus power lens element comprises injecting a melt of thermoplastic material comprising at least one UV absorber at a temperature higher than a glass transition temperature (Tg) of the thermoplastic material in an initial molding cavity delimited by two facing mold inserts. During the injecting, the two facing mold inserts are moved toward one another to define a final molding cavity whose volume is less than that of the initial molding cavity. After cooling and opening of the mold cavity, the plus power lens element is recovered. One of the two facing mold inserts comprises a flat surface facing the initial molding cavity, thereby to form a flat surface on one side of the plus power lens element, and the other of the two facing mold inserts comprises a concave surface facing the initial molding cavity, thereby to form a convex surface on an opposite side of the plus power lens element.
