Abstract

A thermoforming method includes heating a thermoplastic panel (210, 410) to a forming temperature, and compressing the thermoplastic panel between a first tool (230) and a second tool (232), wherein the thermoplastic panel is bent about a first axis (290) extending along a first direction with respect to the thermoplastic panel in response to being compressed between the first tool and the second tool. The thermoplastic panel may then be cooled to a hardened temperature and disposed between a third tool (240) and a fourth tool (242). The method further includes heating the thermoplastic panel to the forming temperature, and compressing the thermoplastic panel between the third tool and the fourth tool, wherein the thermoplastic panel is bent about a second axis (292) extending along a second direction with respect to the thermoplastic panel in response to being compressed between the third tool and the fourth tool.
