Paper Title:
Anti-Sticking Effects of Cr-N and Zr-DLC Films on Microinjection Molding for LGP Applications
  Abstract

Sticking problems in injection molds are a significant challenge in product quality control. Molds are usually coated with a surface ceramic layer to prevent sticking problems. This study presents two films deposited on light-guide plate microinjection molds using an unbalanced magnetron sputtering process to investigate the anti-sticking property of molds. The deposited film materials include chromium nitride (Cr-N) and zirconium containing diamond-like carbon (Zr-DLC). The anti-stick film properties examined here include water contact angles, the coefficients of friction, as well as product flatness for the practical injection process. The results show that the performance of Cr-N films involve water contact angles at 111.4 degrees and a coefficient of friction at 0.742, respectively. The performances of Zr-DLC films involve water contact angles at 86.2 degrees and a coefficient of friction at 0.106, respectively. For the practical injection process, the deposited Cr-N films have better anti-sticking property than do the deposited Zr-DLC films.
