[Case Study] Glass Insert - In-Mold
Breaking the limits of tape adhesion! Achieving a seamless, completely sealed structure and a larger screen.
We would like to introduce a case study that addresses the challenges of narrow bezels and waterproofing in smart devices through glass inserts and in-mold technology. In this case, there was a challenge that narrow bezels and waterproofing could not be guaranteed with conventional tape adhesion. Therefore, we developed a special mold mechanism and adhesive technology that completely integrates fragile glass and resin within the mold. This achieved a seamless, fully sealed structure without the need for tape, as well as larger screen sizes. [Case Overview] ■ Challenges Faced: Narrow bezels and waterproofing in smart devices could not be guaranteed with conventional tape adhesion. ■ Solution: Developed a special mold mechanism and adhesive technology that completely integrates glass and resin within the mold. ■ Value Created: Achieved a seamless, fully sealed structure without the need for tape and larger screen sizes. *For more details, please download the PDF or feel free to contact us.
