Abstract:
A method of effectively bonding a surface application material to an injection molded plastic member, said method comprising:a) providing an injection molding unit having a first mold section and a second mold section, said first mold section and said second mold section forming a mold cavity upon being clamped together;b) clamping said first mold section and said second mold section together thereby forming said mold cavity therebetween;c) providing at least a portion of an intermediary substratum inside said mold cavity, said intermediary substratum having a first side and a second side;d) injecting a plastic injection material into said mold cavity, said plastic injection material contacting and becoming partially absorbed into at least a portion of said first side of said intermediary substratum upon said plastic injection material being injected into said mold cavity;e) allowing said plastic injection material to at least partially cool in said mold cavity to form said plastic member, said cooling of said plastic injection material providing a bonding relationship between said first side of said intermediary substratum and said plastic member;f) removing said plastic member and said intermediary substratum bonded to said plastic member from said mold cavity;g) applying said surface application material to at least a portion of said second side of said intermediary substratum such that said intermediary substratum is located generally between said surface application material and said plastic member, said surface application material becoming partially absorbed into said portion of said second side of said intermediary substratum; andh) allowing said surface application material to harden over time, said hardening of said surface application material over time thereby providing a bonding relationship between said surface application material and said second side of said intermediary substratum.
