    • Disclosed are methods for making an enclosure having a three-dimensionally shaped glass wall portion comprising an initial step of shaping a glass charge into a preform having a preform cross-section corresponding in shape to a smaller cross-sectional shape for the three-dimensional glass wall portion. At least a surface portion of the preform is then finished if necessary to remove any visible optical surface defects therefrom and/or to meet geometric tolerances, and the preform is drawn along an elongation axis perpendicular to the preform cross-section to reduce or draw down the preform in size to the smaller cross-sectional shape for the three dimensional glass wall portion. The smaller cross-sectional shape or sections thereof are then tempered to provide a strengthened glass wall portion having a compressively stressed surface layer thereon.
    • 公开了一种用于制造具有三维形状的玻璃壁部分的外壳的方法,其包括将玻璃电荷成形为预型件的初始步骤,所述预成型件具有对应于形状的预制件横截面以用于三维玻璃的较小横截面形状 壁部分。 如果需要,至少预成型件的表面部分被完成,以从其中除去任何可见的光学表面缺陷和/或满足几何公差,并且预成型件沿着垂直于预成型件横截面的伸长轴被拉伸以减少或拉伸 预成型件尺寸相对于三维玻璃壁部分的较小横截面形状。 然后对其较小的横截面形状或其部分进行回火,以提供其上具有压应力表面层的强化玻璃壁部分。
