Automotive glass tooling — technology, process & solutions
IOCCO pairs process engineering with precision tooling for automotive glass: bending molds, checking fixtures and quenching systems designed around the physics of forming and tempering.
Engineering pillars of automotive glass tooling
Press bending & convection heating for automotive glass tooling
Thermal uniformity and contact strategy drive shape fidelity and optical quality. We design male/ring and heating maps to minimize gradients, stabilize temperature ramps and protect edge zones.
- Heat-up / soak / equalization tuned to glass mass and tooling.
- Ring registration and pressure maps for complex/asymmetric geometries.
- Compatibility with roll-form and air-flotation pre-support.

Quench engineering & stress profile optimization for automotive glass tooling
Quench ring and box determine the compressive stress layer. Our nozzle arrays and balanced plenums target uniform airflow, improved break pattern and energy efficiency.
- CFD-informed plenum design and pressure drop balancing.
- Cooling symmetry for optical quality and repeatability.
- Retrofit kits for existing tempering lines.

Materials & low-adhesion surface finishing for automotive glass tooling
We design and manufacture moulds for automotive glass bending, selecting aluminum, ceramics or stainless steel according to cycle temperature, stiffness and release requirements. Surface roughness and coatings ensure anti-sticking performance and long service life.
- Dimensional stability through repeated thermal cycles.
- Serviceable components for predictable maintenance.
- Edge protection and abrasion control to preserve glass quality.
Digital metrology & checking fixtures for automotive glass tooling
Manual or digital fixtures validate dimension and curvature. We integrate datums, contactless probes and stack-up logic for OEM specs and full traceability.
- Naked glass and tertiary (with gaskets, pins, brackets).
- Automated measurement and SPC/PPAP data logs.
- Closed-loop verification on glass, edge and holes.
Surface compensation & CAD workflow for automotive glass tooling
We model spring-back and thermal deformation, applying surface compensation in CAD (CATIA V5). Simulation shortens tuning loops and stabilizes production.
- Tolerance stack-up and interference analysis.
- Compensation from measurement feedback.
- Faster ramp-up, fewer reworks.
