Abstract
Building panels and methods of making the same are disclosed herein. In one embodiment, a method of injection molding a building panel includes co-mingling a first material and a second material in a molten material, where the second material includes a color that contrasts with the first material. The method also includes injecting the molten material into a cavity of an injection mold, modifying a flow front of the molten material as the molten material flows in the cavity, and cooling the molten material to form a solidified building panel.
Claims21
A method of injection molding a building panel, comprising:
- co-mingling a first material and a second material to create a molten material, the second material comprising a color that contrasts with the first material;
- injecting the molten material into a cavity of an injection mold, wherein the cavity is divided into a first cavity section and a second cavity section, the second cavity section comprising a textured surface simulating wood grain, and wherein the injection mold comprises gate openings through which the molten material flows into the cavity, the gate openings being provided in the first cavity section;
- applying vacuum pressure within the cavity and thereby modifying a flow of the molten material from within the injection mold while the molten material flows in the injection mold;
- and
- cooling the molten material to form a solidified building panel.
