Abstract

A peripherally encapsulated product, such as an oven door outer shell, is molded in accordance with this invention by placing a piece of glass between mold clamping portions of relatively movable closed bodies when the latter are in an open position. Preferably both bodies are heated and thermosetting polymeric material (SMC or BMC) is placed upon selected areas of one of the mold bodies within and about an area corresponding to an annular mold cavity and outboard of a peripheral edge of a piece of glass. The glass is clamped between mold clamping portions of the mold bodies which are then progressively closed creating compression forces which extrude the thermosetting polymeric material into the annular cavity and into complete encapsulation of the continuous peripheral edge of the piece of glass. The handle can be integrally molded during the molding process.

Claims

1. A door comprising a door frame, said door frame including a polymeric/copolymeric synthetic plastic molded material front wall having an outer peripheral edge portion, a handle formed in said front wall inboard of said outer peripheral edge portion, said handle including a finger-receiving opening opening through a handle forming wall portion of said front wall, and said finger-receiving opening being defined by an in situ molded edge of said in situ molded front wall handle forming wall portion.

2. The door as defined in claim 1 wherein said in situ molded edge is continuous.

3. The door as defined in claim 1 wherein said in situ molded edge includes a first edge portion lying substantially in a plane of said front wall and a second edge portion lying in a plane.

4. The door as defined in claim 1 wherein said in situ molded edge includes a first edge portion lying substantially in a plane of said front wall and a second edge portion lying in a plane defining a substantially obtuse angle with said front wall plane.

5. The door as defined in claim 2 wherein said in situ molded edge includes a first edge portion lying substantially in a plane of said front wall and a second edge portion lying in a plane.

6. The door as defined in claim 2 wherein said in situ molded edge includes a first edge portion lying substantially in a plane of said front wall and a second edge portion lying in a plane defining a substantially obtuse angle with said front wall plane.

7. The door as defined in claim 1 wherein said front wall handle forming wall portion is offset from a plane of said front wall.

8. The door as defined in claim 1 wherein a plane through said in situ molded edge corresponds to a parting line plane though opposing mold bodies between which said door is molded.

9. The door as defined in claim 2 wherein a plane through said in situ molded edge corresponds to a parting line plane though opposing mold bodies between which said door is molded.

10. The door as defined in claim 3 wherein a plane through said in situ molded edge corresponds to a parting line plane though opposing mold bodies between which said door is molded.

11. The door as defined in claim 4 wherein a plane through said in situ molded edge corresponds to a parting line plane though opposing mold bodies between which said door is molded.

12. The door as defined in claim 5 wherein a plane through said in situ molded edge corresponds to a parting line plane though opposing mold bodies between which said door is molded.

13. The door as defined in claim 6 wherein a plane through said in situ molded edge corresponds to a parting line plane though opposing mold bodies between which said door is molded.
