High quality and safety of automotive glass

automotive glass

The automotive glass manufacturing process includes various issues that can impair the quality and safety of windshields. One of the biggest challenges is achieving the desired thickness and flatness of the glass during the melting and shaping process. Any deviation from the desired specifications can lead to defects that can weaken the glass, making it unable to withstand stresses such as impacts from potholes, road debris or temperature fluctuations. 

Throughout the manufacturing process, there are various defects that can affect the quality and safety of windscreens, such as impurities or foreign objects getting trapped in the glass, and defects in the glass surface or structure. 

These defects can result in the driver's vision being restricted, structural integrity being compromised, or even the windshield breaking. 

ISRA VISION inline surface inspection detects and classifies all defects and ensures that the highest quality specifications for windshields are met.

Quality Inspection

Our in-line optical inspection systems perform a complete quality inspection on all kinds of automotive glass panes, from rectangular to free-form glass, including clear and privacy glass as well as silkscreen printed glass panes. Suitable for all pane sizes and thicknesses, the systems inspect the entire panel, as well as the edges.  

The systems reliably identify the tiniest scratches even at high-speed conveying, classify quality-related defects and prevent further processing of defective products ensuring a quick return on investment. 

After grinding, the edge inspection system checks the edges of the glass for all typical edge and grinding defects, such as cracks, chips, shiners, and burn marks. The high-precision sensors detect and classify all defects in real time and enable the determination of the ideal replacement time for the grinding wheel and edge cutter.

The in-line optical inspection systems can be integrated into any process environment and can be adjusted to any glass type. Analysis functions for process optimization guarantee high quality, flawless products, resulting in increased customer retention, permanently reduced production and downtime costs.

Optical Power Measurement 

Optical Power Measurement is an essential factor in automotive glass production to ensure that the glass meets the desired specifications for clarity and visual acuity. By measuring the refractive index of the glass, which is the degree to which it bends light, manufacturers can assess the quality and consistency of the glass.

Our automated inspection systems are designed for the inspection of optical defects and shape deviations on reflective and curved surfaces. Developed for use in quality and design laboratories, they precisely inspect optical distortions and the curvature quality of all types of automotive glass.

Measurement of optical distortions

The systems fully analyze all glass and panel types measuring the horizontal and vertical transmitted optical distortions. Using special filters, they accurately identify defect causes in the production process while clearly displaying the recorded inspection results using color coding. This guarantees production quality while also ensuring the optical quality of the ADAS (Automatic Driver Assist Systems) function.

Equipped with ISRA's patented Moiré technology, the inspection systems perform repeatable measurements across the entire panel surface and reliably detect distortions down to the millidiopter range. In a single measurement process, they capture the smallest defects and classify them according to objective criteria. This enables the traceability of production defects and the rejection of defective glass panes.

Evaluation of the curvature quality

Specially developed 3D measurement systems evaluate the curvature quality of all automotive glass types. Based on stereo deflectometry the systems reliably and automatically measure the local curvature on reflective surfaces with high precision in millidiopters.

With ISRA VISION quality inspection systems, you can monitor your processes in detail and simultaneously receive an analysis of the quality criteria. Based on the collected measurement data, you can analyze and optimize the production processes.  

Depending on the requirements, we offer inline inspection systems for real-time operation during production or offline inspection for quality control after production.
