Hybrid molding of in-mold transfer and sheet insert.
Achieving the best of both worlds with sheet inserts that have various optical functions and decorative transfer in-mold!
**Customer Development Needs** We received a request to propose a new in-vehicle CID (Center Information Display) cover for vehicle OEM manufacturers, designed in a dome-shaped 3D format that cannot be achieved with glass bending, and to include optical processing and design elements. **More Specific Requirements** To approach the quality of a high-grade glass cover, the front side was required to have an AR (Anti-Reflection) coating, AFP (Anti-Fingerprint) coating, and a hard coat, while the back side needed a hard coat for outgassing prevention from molded resin, along with decorative design elements. **Our Proposal** We proposed inserting a hard coat sheet with AR/AFP on the surface and believed that the requirements could be met through in-mold transfer on the back side. We established a hybrid molding method that combines both elements and supplied the product. **Customer Evaluation** The product was able to achieve a shape that is impossible to process with bent glass while incorporating low reflection and anti-fingerprint features, resulting in great satisfaction. Based on the adoption of this for the customer's promotional in-vehicle CID module front cover, proposal activities to vehicle OEMs have commenced.
