Tempered Automotive Glass — process overview
The tempering (toughening) process uses controlled heating, bending and rapid quenching to increase strength and safety. IOCCO integrates bending/tempering tooling with stable thermal profiles, precise handling and inline checks to reduce scrap and stabilize optical quality while maintaining takt time.

Pre-process line (cutting → printing)
Process details. Pre-process covers all activities performed on the glass before bending and tempering. After loading, dedicated handling transfers the lites to cutting (including diagonal cutting) and break-out, then to grinding, washing and printing.
- Handling connections for grinding machines and full integration of third-party grinders.
- Integration of drilling machines and coordinated handling.
- Handling connection with washing machines + washing line integration.
- Handling connection with printing machines + printer integration.
- Drying systems for paints with handling connection & integration with UV/IR ovens.
- Inspection within the printing room to verify print quality and positioning.
- Storage/buffer systems to ensure continuous flow toward bending via connection to the tempering furnace.
Bending & tempering — Tempered Automotive Glass
After reaching the target temperature, the glass lite is formed in the Press system and then immediately quenched to achieve tempering. This sequence preserves geometry while developing the required strength and safety.
IOCCO designs and builds different press systems tailored to each model’s geometry, thickness and optical specifications. In the bending stage, the Mold system and the Cooling system are essential for shape accuracy and stability; during tempering, the Blowing system delivers uniform quench airflow for consistent results.
- Press system: precision forming with controlled force and cycle timing.
- Mold system: tooling engineered to model-specific curvature with thermal stability.
- Blowing system: balanced nozzle arrays and pressure control for even quench.
- Cooling system: managed cooling paths to support shape retention post-press.
Unloading & inspection (quality & packing)
Unloading, final inspection & packing. Once the glass has been shaped, lites are unloaded via pick-and-place robotic systems or overhead transfer. A sorting line routes each lite to the shaping check to verify conformance to specifications.
- Unloading & transfer: pick-and-place robots, overhead transfer, and conveyors to quality stations.
- Shaping check: verification of geometry and critical dimensions before downstream operations.
- Handling for inspection: Picking Station & Centering, Flip-Over Unit, and Inspection Lighting Panel for visual and surface checks.
- Packing with paper: dedicated Paper Trimming and Paper Application machines.
- Packing with spacers: Spacer Application Machine for alternate packing methods.
- Transfer & kitting: Transfer Packing Machine and Rotating Packing Table to manage flow, batches and kitting.
- Powder application: powder machines for flat glass, where applicable.
