Integration of narrow bezels and waterproofing for smartphones using Glass Insert Molding (GIM).
"Narrow frame," "seamless," "with decoration." We integrate the resin frame and glass using Glass Insert Molding (GIM).
I want to maximize the screen without changing the device size. —— We have responded to your request by making the frame as thin as possible through the integrated molding of glass and resin frame (Glass Insert In Mold = GIM), while also ensuring waterproofing. We collaborated with the manufacturer to print decorative designs and bonding binders on the back of the glass, using inks that bond with the heat of the molded resin. The bonding strength is quantitatively managed, and the waterproof performance is guaranteed through a complete airtight inspection. Utilizing the nature of in-mold transfer, which "transfers to the resin frame but not to the glass," allows us to complete the frame decoration simultaneously with molding, which is also a feature. It has been adopted by domestic and international set manufacturers and has expanded its achievements to insert curved glass as well. 【Download Materials & Inquiries】 You can view the catalog and case studies for problem-solving by selecting "PDF Download."
