A method of manufacturing a panel utilizes a first mold half (12) having a peripherally extending rib (24) and a second mold half (14). The first mold half (12) is moved relative to the second mold half (14) to define a first mold cavity with the rib extending into the first mold cavity. A first molten material (20) is injected into the first mold cavity and allowed to solidify to thereby form a notch (26) within the first solidified material (20) corresponding to the shape of the rib (24). A second mold cavity is formed which has a flow path between the first solidified material (20) and the first mold half (12) comprising a series of sharp turns which present a barrier to material flow. A second material (30) is injected into the second mold cavity and allowed to cure on the first solidified material.
