Abstract

It is still a challenge to achieve the polymer replication of high aspect ratio micro-structured surface especially when the completed and unified replication quality is required. This paper shows a new method for the replication named ultrasonic vibration micro-injection mold (μUVIM) technology which combines the micro-injection mold (μIM) with ultrasonic vibration. An experimental mold that integrates micro-injection compression mold (μICM) and μUVIM has been designed. In this paper, the effect of important process parameters on the replication quality of microstructure was studied via μUVIM experiment, and the process parameters were optimized through the response surface method (RSM). Compared with replication methods based on μICM technology, the μUVIM technology discussed in this paper can increase the average height of the microstructure by 14.6% and increase the production efficiency by three times. Moreover, it has been found that the μUVIM technology is insensitive to the thickness of the polymer substrate, so it can widen the processing scope of microstructure with high aspect ratio.
