Title: | Research on continuous injection direct rolling process for PMMA optical plate | Authors: | Wang, HX Lv, YH Li, JB Lou, Y Kong, LB |
Issue Date: | 2014 | Source: | Advances in mechanical engineering, 2014, 971756, p. 1-9 | Abstract: | Continuous injection direct rolling (CIDR) combined intermittent injection and rolling process is a new technology for molding optical polymer plates with microstructured patterns; research on forming PMMA optical plates is an aspect of it in this paper. The equipment of CIDR process consists of plastic injection module, precision rolling module, and automatic coiling module. Based on the establishing mathematical CIDR models, numerical analysis was used to explode the distribution of velocity, temperature, and pressure in injection-rolling zone. The simulation results show that it is feasible to control the temperature, velocity, and injection-rolling force, so it can form polymer plate under certain process condition. CIDR experiment equipment has been designed and produced. PMMA optical plate was obtained by CIDR experiments, longitudinal thickness difference is 0.005 mm/200 mm, horizontal thickness difference is 0.02/200 mm, transmittance is 86.3%, Haze is 0.61%, and the difference is little compared with optical glasses. So it can be confirmed that CIDR process is practical to produce PMMA optical plates. | Publisher: | SAGE Publications | Journal: | Advances in mechanical engineering | ISSN: | 1687-8132 | EISSN: | 1687-8140 | DOI: | 10.1155/2014/971756 | Rights: | Copyright © 2014 Hai Xiong Wang et al.
