| Popis: | In this paper, we have proposed a novel hydrostatic forming process for fabricating large micropatterned polymeric plates; this process is suitable for mass production. The key idea of the process is to hydrostatically form a number of vacuum-packed stacks, each composed of a workpiece and a polymer die in a large water-containing vessel, by controlling the temperature and pressure of water as the pressure-transmitting medium. A prototype hydrostatic press system has been developed to simultaneously form 25-μm microprismatic structures on 30 pieces of PMMA plates (dimensions: 265 × 172 × 0.7 mm) within a cycle time of 35 min. The formed parts are examined at both microscopic and macroscopic levels, and the results are discussed. |
