Application
With the rapid development of intelligent cockpits and advanced driver assistance systems, Head-Up Display (HUD) modules and automotive display cover glass place increasingly stringent requirements on optical coating performance. High visible-light reflectance, long-term film stability, and batch-to-batch consistency have become critical evaluation criteria.
Magnetron sputtering–based optical coating processes are now widely recognized as the mainstream technology route for HUD and high-end automotive display glass manufacturing.
Customer Challenges
Limited throughput and loading capacity
Conventional coating systems typically offer restricted batch size per run, making it difficult to meet high-volume mass production requirements.
Extremely tight film uniformity requirements
HUD applications demand precise control of reflectance, refractive index, and film thickness, with very low tolerance for process fluctuations.
Difficulty in integrating multifunctional coating stacks
Frequent process switching and multiple coating steps reduce production efficiency and negatively impact overall yield.
Zhenhua Vacuum Solution
Zhenhua Vacuum introduces the GFM1916 Magnetron Sputtering Optical Coating System, featuring a highly automated sputtering platform combined with ion source assistance and precision thickness control.
The system enables stable mass production of high-performance optical coatings for HUD modules and automotive glass cover applications, delivering a balanced solution of high throughput, excellent consistency, and process flexibility.
Key Equipment Advantages
Fully automated process control for stable operation
End-to-end automated control ensures simplified operation, high process repeatability, and reliable performance in continuous production environments.
High loading capacity and large-scale productivity
The cylindrical substrate carrier design doubles the single-batch loading capacity compared to conventional electron beam evaporation systems, while supporting multiple substrate geometries for flexible applications.
Superior optical film performance
The PVD + CVD hybrid coating architecture, combined with ion-assisted deposition (IAD), produces dense films with high and stable refractive indices and excellent adhesion. The system supports one-pass deposition of aluminum reflective layers, dielectric layers, and AF (anti-fingerprint) coatings.
Precision coating control meeting stringent HUD standards
Equipped with a quartz crystal monitoring system for accurate thickness control, together with the SPEEDFLO closed-loop and fully automated control system, the SiO₂ deposition efficiency is significantly improved. Visible-light reflectance is consistently maintained above 90%, fully meeting the demanding optical performance requirements of HUD applications.
