A thrust reverser cascade basket and method including an elongated metal frame having elongated metal strongbacks and metal transverse end portions joining opposite ends of respected strongbacks. Reinforced hard plastic is pressure injection molded on the strongbacks, and transverse vanes formed of the plastic extend between the strongbacks and are integral therewith. The strongbacks have openings having the plastic molded therein, the openings being between the vanes, and substantially all plastic knit lines are formed along strongback surfaces, spaced adjacent mid-span locations between the vanes. The vanes are free of the knit lines.
