Convenient nut inserts for fitting with the chassis body, compatible with sheet metal inserts! (Sheet metal inserts also contribute to rigidity and warping prevention!)
【Customer Development Needs】 We were requested to insert metal parts to improve the assembly compatibility with the casing body in LCD panels for mobile devices. 【More Specific Requirements】 1. We would like you to insert nuts for screws during the molding process to securely hold them on the back of the in-mold transfer molded product. 2. Since the resin frame of the Glass Insert Molding (GIM) is thin and cannot achieve a fitting structure, we want to insert sheet metal simultaneously to enhance assembly compatibility with the casing. 【Our Proposal】 1. We developed an automatic feeder device that identifies the front and back of the nuts for insertion, and in conjunction with the in-mold transfer method, we proposed an LCD panel with decorative features and back-mounted nuts. 2. We proposed a GIM method with sheet metal inserts, partially hollowing out SUS sheet metal to allow the molded resin to fill in and securely hold the narrow frame. 【Customer Evaluation】 1. Thanks to the strong nuts inserted into the decorative LCD window, we received positive feedback from various mobile device manufacturers regarding improved assembly compatibility with the casing body. 2. We successfully addressed the need to balance the narrow frame design of GIM with assembly compatibility with the casing body, receiving high praise from users.
