ABSTRACT:
A process for forming an encapsulated window assembly including a gasket member surrounding a peripheral region of a transparent sheet and a peripheral seal secured to the gasket member. The peripheral region of the transparent sheet, as well as a preformed periphery seal assembly, are positioned within a mold cavity. The periphery seal assembly includes an elastomeric seal secured to a seal support member, with the seal support member being relatively rigid as compared with the elastomeric seal. The mold is closed, bring the mold sections into facing relationship, whereby opposed surfaces of the seal support member of the periphery seal assembly are engaged between a surface of the first mold section and a surface of the second mold section. A molding material is injected into the mold so as to fill the mold cavity, is allowed to solidify, and the mold is opened and the encapsulated window assembly is removed. The invention also relates to the resulting encapsulated glazing unit and mold apparatus.
