    • The present invention provides a method for manufacturing a plate workpiece by a surface microstructure. Prior to press molding, a preform is arranged between a first mold and a second mold having patterns and is arranged in the second mold. Then, the first mold and the second mold are heated to a transition temperature of the preform and then is pressurized with respect to the preform and a pattern preform is obtained through sealing impression of a pattern on the preform. Lastly, the patterned preform is cooled and contracted with the second mold and the plate workpiece having the surface microstructure is obtained. Since the patterned perform is uniformly cooled from a lower portion to an upper portion by thermal conduction, a temperature field is isothermal in horizontal distribution. Accordingly, the plate workpiece having the surface microstructure can be obtained with high accuracy, which is useful in maintaining multiple optical fibers in optical communication.
    • 本发明提供一种通过表面微结构制造板材的方法。 在压制成型之前,将预成型件布置在具有图案的第一模具和第二模具之间,并布置在第二模具中。 然后,将第一模具和第二模具加热至预成型件的转变温度,然后相对于预成型件加压,并且通过预型件上的图案的密封印模获得图案预成型件。 最后,图案化预成型件被冷却并与第二模具收缩,并获得具有表面微结构的板材工件。 由于图案化的表面由热传导从下部均匀地冷却到上部,所以温度场在水平分布中是等温的。 因此,可以高精度地获得具有表面微结构的板状工件,这对于维持多个光纤在光通信中是有用的。
