Etching Micromachining of Micro-structure Arrays on Injection Mold Cavity Surface

Huang Hongguang;Guo Zhongning;Yang Quan;Guangzhou Automoible Group Co.,Ltd.;Guangdong University of Technology;  
A simple mask was designed,and smooth rally micro-structure was researched.It is found that spray pressure is of significant influences on the micro-structure feature,the etching depth and undercut will increase per unit time when spay pressure is growing.Different processing method with controlled spay pressure was integrated to machine rally micro-structure,such as smooth rally micro salient and gradual depth rally micro-structure.Finally,a large rally smooth micro-structure with diameter of 200μm,depth of 60μm was machined.
