Integrated Semi-Convertible Sunroof System

This is the first all-thermoplastic, 1-piece GR SMA/ABS composite sunroof frame that is 2x1 m in size. Large sunroof frames such as this are typically formed from aluminum extrusions or steel stampings, while smaller frames have been produced in SMC or hybrid PBT/ASA and metal. The integrated system combines 7 parts into 1 while incorporating both structural and customer-visible surfaces with an integrated textile canopy plus kinematics. The injection-molded frame is mounted to the upper-body structure and combines operating functionality for a sliding sunroof.  Tooling was designed to simultaneously mold both sunroof frame plus rear-window frame via a sophisticated runner and hot-drop system that minimized part stresses, and eliminates cooling fixtures, a second tool, and a second press, and provided repeatable manufacturing. The result is a durable system that is 100% recyclable, eliminates paint (lowering VOC emissions), offers 40% lower weight than previous systems, and contributed 25% tooling savings.
