Claims
- 1. An integral formed molded product with a convex surface, said molded product being formed of a heat curable reactive thermoset polymer resin molding powder containing an integrally formed insert which bonds to said heat curable reactive thermoset polymer resin during molding thereof, and which insert provides attachment of said integrally formed product to a frame or support structure, including a boss with a top projecting from said convex surface, a supporting feature supporting said boss which supporting feature extends from the top of said boss to said convex surface, wherein said supporting feature partially surrounds said boss.
- 2. The integral formed molded product of claim 1 wherein the angle formed by a vertical line projecting outward from the center of said insert and said supporting feature is between 30-75 degrees.
- 3. The integral formed molded product of claim 1 wherein the supporting feature is of a conical shape.
- 4. The integral formed molded product according to claim 1, wherein the heat curable reactive thermoset polymer resin molding powder comprises an amino resin based molding powder.
- 5. The integral formed molded product according to claim 4, wherein the amino resin based molding powder comprises urea/formaldehyde, melamine/formaldehyde, or mixtures thereof.
- 6. The integral formed molded product of claim 1, wherein said insert is a threaded fastener.
- 7. The integral formed molded product of claim 1, wherein said insert is retained prior to bonding to said heat curable reactive thermoset polymer resin by a magnet contained in a mold base.
- 8. A method for forming an integral formed molded product with a convex surface, comprising:(a) supplying a heat curable reactive thermoset polymer resin molding powder; (b) supplying an insert which bonds to said heat curable reactive thermoset polymer resin; (c) supplying a mold with a convex shape including openings to receive said insert during molding thereof; (d) securing said insert to said mold wherein said mold includes a cavity which forms a boss on said molded product which boss projects from said convex surface of said molded product, said boss including a top, said cavity forming a supporting feature supporting said boss which supporting feature extends from the top of said boss to said convex surface; (e) substantially filling said mold with said thermoset polymer resin molding powder, including said cavity forming a supporting feature, and (f) curing said heat curable reactive thermoset polymer resin molding powder to form said product wherein said product includes said boss projecting from said convex surface including said supporting feature supporting said boss which supporting feature extends from the top of said boss to said convex surface.
