METHOD OF MANUFACTURING PLATE WORKPIECE WITH SURFACE MICROSTRUCTURES

摘要

A method of manufacturing a plate workpiece with surface microstructures is provided. Before press-molding, a preform is placed between a first mold with a pattern and a second mold, and is disposed on the second mold. Next, the first mold and the second mold are heated to a transition temperature of the preform, and then pressed against the preform to impress the pattern onto the preform to obtain a patterned preform. Finally, the patterned preform is cooled with the second mold and shrunk to obtain the plate workpiece with surface microstructures. Since the patterned preform is uniformly cooled from bottom to top by thermal conduction, the temperature field is isothermal in a horizontal distribution. Therefore, a plate workpiece with high accuracy surface microstructures is obtained, and is useful for carrying multiple optical fibers in optical communication.

1. A method of manufacturing a plate workpiece with surface microstructures, comprising the steps of:
(A) providing a press-molding apparatus, having:
a first mold having a first surface and a pattern formed on the first surface of the first mold; anda second mold facing to the first surface of the first mold; (B) placing a preform on the second mold and between the first mold and the second mold; (C) heating the first mold and the second mold to a temperature at which the preform is capable of being press-molded; (D) pressing the first mold and the second mold against the preform, thereby impressing the pattern of the first mold onto the preform to obtain a patterned preform; and (E) cooling the second mold and parting the patterned preform from the first mold, so as to obtain the plate workpiece with the surface microstructures.
