    • A reforming mandrel and a method of using it to reform glass are described. The reforming mandrel 100 comprises an upstream portion 120, a downstream portion 140 and an at least partially hollow interior 160. The upstream portion has an intake inlet 122 for fluid flow. The downstream portion 140 is axially spaced from the upstream portion 120. The downstream portion 140 has a flattened cross-section defined by flattened peripheral portions 142 joined by curved peripheral portions 144. At least one curved peripheral portion is made of porous material resistant to a temperature of at least 1000 °C, e.g. graphite. The at least partially hollow interior 160 of the mandrel communicates with the intake inlet 122 and the porous material. The hollow interior may extend into further hollow passages 170,172,174,176. A substantially cylindrical glass tube 400 is reformed by drawing the heat-softened tube over the mandrel 100, fed with gas, to prevent adhesion to the shaping tool, via the porous material to form a gas cushion, and so to reform its shape into a 3-dimensional formed glass sleeve with a flattened portion, without imperfections such as streaks. Of particular use in making a glass cover (integrated front and back) for a smartphone or similar device.
    • 描述了一种重整心轴及其使用它来改造玻璃的方法。 重整心轴100包括上游部分120,下游部分140和至少部分中空的内部160.上游部分具有用于流体流动的进气入口122。 下游部分140与上游部分120轴向间隔开。下游部分140具有由弯曲的周边部分144连接的扁平的外围部分142限定的扁平横截面。至少一个弯曲周边部分由多孔材料制成, 至少1000℃的温度,例如 石墨。 心轴的至少部分中空的内部160与进气口122和多孔材料连通。 中空的内部可以延伸到另外的中空通道170,172,174,176中。 通过将热软化管拉过心轴100,供给气体来重新形成基本上圆柱形的玻璃管400,以通过多孔材料防止与成型工具的粘附,以形成气垫,从而将其形状改造为 具有扁平部分的三维成形玻璃套筒,没有缺陷如条纹。 特别用于制造用于智能手机或类似设备的玻璃盖(集成的前后)。
