Engineering the futureof automotive glass
We design and build machinery and complete automotive glass lines, from glass preparation to ready-to-install glazing. We work with some of the world’s leading automotive glass manufacturers.
Discover the production routesThe product route
Shared operations. Dedicated processes
Preparation, inspection and handling connect both routes. The core processing stages depend on the type of glass.
Tempered
Backlites and sidelites
Post Glass: finishing and components, according to the product. Line integration connects the different stages.
01 / Shared by both routes
Sheet preparation
From loading to furnace-ready glass.
Handling and buffers connect cutting, breaking, grinding, drilling, washing and printing. The project defines interfaces with process machines, including those from other manufacturers.
Loading, cutting and breaking
Pre-processing prepares sheets before bending or tempering. The flow is designed around the product and the planned machines.
- Sheet loading and transfer.
- Connection to cutting, including diagonal cutting, and break-out.
Grinding and drilling
Handling connects the operations and coordinates their infeed and outfeed.
- Feeding and integration of third-party grinding machines.
- Connection to drilling machines and transfer management.
Washing, printing and drying
The line connects surface preparation, decoration and print inspection.
- Integration of washers and printers.
- Paint drying and connection to UV/IR furnaces.
- Quality and position inspection in the printing room.
Buffer and furnace entry
Sheet buffering and retrieval link pre-processing to the next cycle.
02 / Process differences
Forming, tempering and lamination
Two distinct routes, developed around the product.
Laminated
Assemble glass and interlayers
Sheet bending, interlayer preparation and assembly precede de-airing and the final autoclave cycle.
Bending furnace loading and unloading
Pairs are fed from racks or conveyors. Mechanical references and vision support inner/outer identification, pairing and positioning on bending supports.
- Support identification and sequence management.
- Unloading from the cooling area and transfer to washing.
- For press bending: single-sheet feeding and positioning with dedicated equipment.
Bending tooling for laminated glass
I.NTEGRA develops press bending tooling for laminated glass, configured around product geometry and line interfaces.
The EPBl family includes a heated ceramic press male and an adjustable heated ring. Roller systems or an air-flotation table, quench ring, vacuum hood and drop-down system complete the configuration according to the process.
Explore laminated glass tooling · I.NTEGRAPVB preparation and feeding
While the glass is prepared, the interlayer follows its own route. PVB preparation includes unwinding, buffering and relaxation, followed by cutting and placement on trays. The automatic feeding system delivers material to the assembly room.
UnwindingBufferingRelaxationCuttingTraysLay-up
The configuration must relate the material format to the glass geometry. For functional interlayers and different compositions, preparation is verified against the product specifications.
Assembly lines
IOCCO assembly lines combine glass, adhesive and technological interlayers, and a further glass sheet. Fully robotic solutions and manual assembly lines are available.
Fully robotic assembly lines
The line integrates interlayer sheet separation and cutting, glass localisation using machine vision, and layer assembly with cameras guiding robot positioning.
Before placement on the glass, the interlayer is cut to the glass shape using dedicated cutting machines with a vision and nesting system developed by IOCCO.
Manual assembly lines
On manual lines, operators position the interlayers and stack the glass sheets. Workstations and workflow are configured to suit the geometry, product composition and production requirements.

Assembly and box furnace for batch production
The batch production line connects manual assembly to box furnace treatment. It can accommodate different glass types and shapes by verifying the compatibility of bags, trolleys and recipes. It is a dedicated route for prototypes, replacement glass and variable mixes.
The layout connects the manual loading area, glass preparation and furnace. Batch capacity and residence time are defined according to the version and the glass to be treated.
Checks after de-airing
Verification links the product, thermal parameters, vacuum and test results according to the inspection plan. The glass continues to the autoclave.
Autoclave loading and unloading
The autoclave cycle completes lamination. IOCCO systems handle glass loading and unloading, connecting this stage to the line flow according to the scope of supply.
Interlayer trimming (PVB)
Trimming removes excess interlayer along the edge of the laminated glass. The station is integrated into the production flow and configured to suit the product geometry.
After trimming, final washing prepares the glass for subsequent checks and end-of-line operations.
Tempered
Form and temper glass
Pressing, moulds, blowing and cooling work together to achieve the required geometry and treatment.
Forming, tempering and furnace feeding
The project coordinates furnace entry, forming, tempering and exit. Geometry, thickness and optical specifications guide the system.
- Press system: forming force and timing.
- Mould system: surfaces and thermal stability of the moulds.
- Blowing system: nozzles and quench flow distribution.
- Cooling system: cooling after pressing.
After the furnace
The glass is picked up and presented for inspection, then protected and placed in the specified container.
Go to inspection and packing03 / Shared functions, specific checks
