In one embodiment, a molding system for creating a molded-in-color panel has a first mold member with a first forming surface for forming a portion of a panel with an exposed surface. The molding system has a second mold member having a second forming surface for forming a concealed portion of the panel. One of the first and second mold members is translatable relative to the other to collectively receive a heated molded-in-color resin to form the panel. The molding system has an injector for injecting molded-in-color resin into the mold. The second forming surface is sufficiently smooth so that the exposed surface of the panel is free of visible flow lines.

The molding system of claim 1 wherein the injector further comprises: a sprue portion to receive heated molded-in-color resin from the injector;a runner to transmit the heated molded-in-color resin therethrough, the runner having a first end in communication with the sprue and a second end;a gate portion in fluid communication with the second end of the runner to one of the first mold member and the second mold member; anda cold slug well portion in fluid connection with the second end of the runner to inhibit impurities in the heated molded-in-color resin from entering the one of the first mold member and the second mold member;wherein the cold slug well portion has a length that is approximately one and a half times greater than a diameter of the runner. 3. The molding system of claim 2 wherein the runner is further defined as a first runner portion in fluid communication with the sprue, a second runner portion in fluid communication with the first runner portion, and a third runner portion in fluid communication with the gate, the cold slug well portion and the second runner portion such that the first runner portion is in fluid communication with the second runner portion with an angle approximately equal to ninety degrees and the second runner portion is in fluid communication with the third runner portion with an angle approximately equal to ninety degrees. 4. The molding system of claim 2 wherein the gate redirects the heated molded-in-color resin from the runner approximately ninety degrees. 5. The molding system of claim 2 wherein the runner is further defined as a first runner portion in fluid communication with the sprue, a second runner portion in fluid communication with the first runner portion, and a third runner portion in fluid communication with the gate, the cold slug well portion and the second runner portion such that the first runner portion and the third runner portion are generally parallel. 6. The molding system of claim 5 wherein the first runner portion is generally perpendicular to the second runner portion. 7. The molding system of claim 5 wherein the second runner portion is generally perpendicular to the third runner portion. 8. The molding system of claim 5 wherein the second runner portion is generally perpendicular to the first runner portion and the third runner portion. 9. The molding system of claim 5 wherein the cold well portion is generally aligned with the third portion. 10. The molding system of claim 1 wherein the first and second mold members collectively provide an outer body for the panel. 11. A system comprising: a first mold member for forming an exposed portion of a molded-in-color panel;a second mold member for forming a concealed portion of the panel having a tolerance such that a height change of a projection along the concealed portion does not exceed fifteen percent of a thickness of the panel; andat least one punch provided within one of the first or second mold members, the at least one punch being actuatable to form an aperture through a partially cooled panel;a nest provided in the other of the first mold member such that the at least one punch extends to through to the nest to nest therein;wherein at least one of a punch surface and a nest surface is substantially coplanar with a flow surface of the second mold member so that a height difference between the flow surface of the second mold and the at least one the punch surface and the nest surface and has a height difference that does not exceed fifteen percent of a thickness of the panel so that any projection along the concealed portion ensures the exposed portion of the panel is free of visible flow lines and wherein the tolerance along the concealed portion ensures that the exposed portion is generally free of surface defects. 12. The molding system for creating a molded-in-color panel the molding system comprising: a first mold member having a first forming surface for forming a portion of a panel with an exposed surface;a second mold member having a second forming surface for forming a concealed portion of the panel, one of the first and the second mold members being translatable relative to the other to collectively receive a heated resin with a molded-in-color to form the panel, second forming surface having a tolerance such that a height change of a projection along the second forming surface does not exceed fifteen percent of a thickness of the panel;an injector for injecting molded-in-color resin into the first and second mold members;at least one punch provided within one of the first or second mold members, the at least one punch being actuatable to extend through the forming surface of one of the second mold member and being actuatable to form an aperture through a partially cooled panel; anda nest provided in the other of the first mold member such that the at least one punch extends to through to the nest to nest therein;wherein at least one of a punch surface and a nest surface is substantially coplanar with the surface the second forming surface so that a height difference between the forming surface of the second mold and at least one of the punch surface and the nest surface and has a height difference that does not exceed fifteen percent of a thickness of the panel so that any projection along the concealed portion ensures the exposed surface of the panel is free of visible flow lines and wherein the height tolerance along the concealed portion ensures that the exposed surface is generally free of flow lines adjacent any projections.
