A method of molding a peripherally encapsulated piece of glass under heat and pressure using molding compound presented in a sheet material (smc) or bulk molding compound (BMC), and a door glass piece.

摘要

Method of molding a product having a peripheral encapsulation, said method comprising the steps of: (a) providing a multipartite mold including at least two bodies (51, 52) of the mold which are capable of being displaced relative to each other and define They are closed continuous annular chamber (60) of the mold which is open towards the inside and inside the annular chamber opposing mold clamping portions (74, 101) of the mold; (B) placing a piece of glass (15) between the parts (74, 101) are mold holding portions when the mold bodies are in a position that they are open; (C) heating at least one of the mold bodies; (D) placing thermosetting polymeric material upon the heated mold body within and throughout an area corresponding to the annular chamber (60) and on the outside with respect to a substantially continuous peripheral edge (18) of the glass piece; (E) hold the glass piece (15) between the parts (74, 101) of the mold which are holding portions; (F) moving relative progressively bodies (51, 52) of the mold taking them to the closed position thereof to thereby create compression forces which extrude the thermosetting polymeric material thus causing the same fill ring (60) chamber and perform a complete encapsulation of the continuous peripheral edge (18) including within said encapsulation surfaces of the opposite faces and a surface of the peripheral edge; (G) curing the thermosetting polymeric material by applying heat and pressure while the mold is in its position in which it is closed; (H) relatively moving the bodies (51, 52) of the mold taking them to their position in that they are open; and (i) withdrawing from the chamber (60) of the mold product peripherally encapsulated.
