Method of Co-Molding

摘要

The disclosure is directed to a method for co-molding. A first element has a top surface, an edge, and a protuberance with a base extending down from the top surface. A second element has an edge, an upper surface, and a lower surface.;The mold includes a first mold portion defining a co-molding upper surface, and a second mold portion defining a co-molding mold cavity. The first element is placed into the second mold portion with the protuberance base in contact with the second mold portion. The second element is placed on top of the first element. The mold is closed, thereby producing the second element as a chamber.;Fluid under pressure introduced into the chamber forces the second element to conform to the shape of the mold, thereby to affix the first element to the second element. Energy is applied to the mold to co-mold the elements together.

1. A method for producing a co-molded article, the article comprising a first element having a top surface, an edge, and a protuberance with a base extending downward from the top surface, and a second element having an edge, an upper surface, and a lower surface, the method comprising the steps of:
preparing a two-piece mold comprising a first mold portion and a second mold portion, the first mold portion defining a co-molding upper surface, and the second mold portion defining a co-molding mold cavity into which the first and second elements are received; placing into the second mold portion, the first element with the protuberance base in contact with the second mold portion; placing into the second mold portion, the second element on top of the first element; closing the first mold portion and second mold portion into abutting relationship thereby forming the second element into a chamber; introducing a fluid under pressure into the second element chamber to force the second element upper surface to conform to the shape of the co-molding upper surface, and the second element lower surface into conform to the shape of the first element top surface thereby to affix the first element to the second element; and applying energy to the mold to co-mold the first and second elements together.
