Paper Abstract

With the development of precision glass molding (PGM), low Tg glass molded lens are more and more used in optical system, recently, especially in the fields of safe security and car assist system, which have large market demand. Coating technology for mold is one key of support technology for precision glass molding, and the researches on the coating for precision low Tg glass molding is urgently needed. In this paper, aiming at the coating technical demand of low Tg glass molding, the coating duration and damage principal are discussed after fast coating facility testing. Three kinds of coating system (WxCy-PtIr-D_ZK3,WxCy-CrAlN-D_ZK3, WxCy-TiAlN-D_ZK3)for molding are analyzed with SEM. The results show the PtIr alloy coating is suit for low Tg glass precision molding.
