摘要:
Disclosed herein is a molded laminated structure having negative draft angles and methods of manufacturing a molded laminated structure having negative draft angles. A preliminary structure having a first outer layer and a second outer layer is molded with a bend that divides the preliminary structure into two sections with an angle between the two sections of less than 180-degrees. Portions that extends from the sections are at positive draft angles. A groove is formed in the preliminary structure at the bend but not formed in a constant cross-section of the second outer layer. The preliminary structure is folding along the bend to at least partially close the groove and form a molded laminated structure with portions that extend at a negative draft configuration while retaining the second outer layer continuous throughout the molded laminated structure.
