Abstract
Conventional injection molding system for producing extremely thin-wall parts such as Light Guide Plates(LGP's) for mobile displays is at the limit of its capability due to its tendency to develop frozen layers and the critical speed of injection. The molten polymer in the cavity freezes quickly as its heat is rapidly transferred to the mold base. Many attempts have been tried in the past to overcome this problem. The present study used the injection/compression molding technology to produce a thin-wall part, with enhanced features such as an automated mechanism for cutting gates. As a result, the total cycle time was reduced by almost 35 seconds, resulting in a productivity increase by 30%.
