Two-shot tube retention fastener molding method
First Claim
1. A two-shot tube retention fastener molding method, wherein the tube retention fastener includes a first shot body member having a pair of deflecting wings, with each of the pair of deflecting wings extending angularly toward each other from one of a pair of side walls, and a second shot isolation member bonded along an interior surface of each of the pair of deflecting wings, the method comprising:
- molding the first shot body member, including the pair of deflecting wings;
molding the second shot isolation member while;
supporting an exterior wing surface of each of the pair of deflecting wings against a first mold surface;
supporting a first portion of the interior surface of each of the pair of deflecting wings against a second mold surface and leaving a second portion of the interior surface of each of the pair of deflecting wings unsupported to define a portion of a mold cavity of the second shot member extending from a distal end of the deflecting wing to the pair of side walls.

Abstract
A mold and molding process for a first shot body member includes a pair of side walls, a semi-circular sleeve positioned between the pair of side walls to define a portion of a longitudinal pocket, and a pair of deflecting wings. Each deflecting wing is coupled to one of the side walls at a corner. A second shot isolation member of an elastically resilient second material is bonded to portions of an interior surface of the longitudinal pocket defined by each of: the semi-circular sleeve, each of the pair of side walls, each of the pair of corners, and each of the pair of wings. Mold members can include supporting surfaces to support interior and exterior portions of the wing during the second shot molding operation, while leaving an exposed interior bonding surface that defines a portion of the second shot molding cavity.

9. A two-shot tube retention fastener molding method, wherein the tube retention fastener includes a first shot body member having a deflecting wing extending angularly toward an opposite one of a pair of side walls, and a second shot isolation member bonded along an interior surface of the deflecting wing, the method comprising:
-
molding the first shot body member, including the deflecting wing; molding the second shot isolation member while; supporting an exterior wing surface of the deflecting wing against a first mold surface; supporting a first portion of the interior surface of the deflecting wing against a second mold surface and leaving a second portion of the interior surface of the deflecting wing unsupported to define a portion of a mold cavity of the second shot member extending from a distal end of the deflecting wing to the pair of side walls. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)
