ABSTRACT:
A mold apparatus and method for forming encapsulated glass which includes the use of a plurality of mold sections 10 and 12 which, when closed, cooperate with a sheet 5 and at least one seal 25 to define a gasket forming cavity 35. When a gasket forming material is injected into the gasket forming cavity 35 and is allowed to at least partially cure, a gasket 2 is formed on at least a portion of the sheet 5 to produce a window gasket assembly 50. A seal 25 with an outwardly angled facing portion 27 defines an interior face 37 of the gasket forming cavity 35 and prevents leakage of the gasket forming material and the formation of flash on the sheet 5. In one embodiment of the invention, the mold section 12 is made of a resilient material and mold section 10 is made of a rigid material. In another embodiment of the invention, mold section 12 has positioned therewithin a rigid member 45 having a finishing surface 48 which cooperates with the seal 25 and the sheet 5 to define a gasket forming cavity 35. The finishing surface 48 of the rigid member 45 defines a face portion of the window gasket assembly 50. Preferably, one of the mold sections 10 and 12 is made of a resilient resin material and the other mold section is made of a rigid resin material, with the rigid mold section 10 having the rigid member 45 positioned so that the finishing surface 48 defines a face portion of the window gasket assembly 50 to be formed.
