| Abstract: | In order to solve the problems in the micro injection molding, some measures of improvement in the plasticizing, injection, metering units, and monitoring system were proposed. The special methods of temperature controlling, vacuuming venting, inserts material selecting, and mold fabricating for micro injection were discussed. The test methods for products were explained. Furthermore, the applicability of micro fluidic simulation software was evaluated. |
