Laminated glass

Preprocess phase consists of those activities made on glass, preliminarily to the bending and consequent assembly.

After loading, the glass through handling machines is transferred to cut, brake and grinding machines, and then to washing and printing machines.

Iocco is able to design and supply handling connection for grinding machines and also to perform integration of grinding machines, handling  connection with washing machines, integration of washing machines, handling connection with printing machines and integration of printing machines as well.

It is opportune that the production line is equipped with storing systems to  guarantee the glass flow continuity directing it towards the bending by means of connection with bending furnace.

The advantage of integrating the different preprocess equipment guarantees to the Client the plant total management through a sole supervising  software.

Shaping Check, before assembly, is a preliminary phase where glass is subject to. Grid check follows to ensure the integrity of the printing circuit,  where existing. Before washing, the pair of glasses is divided and flipped wings down to better remove possible impurities. Once the pair of glasses is bent, the unloading system for bending furnace is performed by a dedicated equipment in order to free the mold from the glass.

In the meantime PVB Pre-Processing – Trimming and Lay Up phases take place to unwind and accumulate vinyl interlayer.  This is subsequently stretched to better adhere to glass, then it is cut, stored on trays and handled through an automatic tray feeding system  to ease Assembly the PVB/Glass by the operators in the assembly room. The Assembly can be performed either automatically or semi-automatically.

The pair of glasses undergo a Pre-Pressing phase to keep the right alignment between inner and outer glass.

A fundamental step in laminating production is the De-airing, to be obtained through either Vacuum Bag Furnace or Vacuum Ring Furnace.  The two mentioned systems adopt different technology and grade of sophistication according to the production needs, in terms of flow rate and manpower, and require significantly diverse financial commitments. Once Deairing is completed, Check After Deairing is performed and glass  is generally subjected to Mirror Boss and Rain Sensor Applications in case of windshields, using different technologies. With regard to sunroofs and sidelights, other types of components and devices are applied.

Automatic Loading and unloading autoclave conveyor system allows a continuous feeding into autoclave.

At the exit of the Autoclave, laminated glass undergoes PVB trimming operation and, after final washing, it enters in the Final Inspection Line.

The product validation phase is carried out through optical inspections and special devices that scan the product.
In the final line, a dedicated station receives the laminated glass on a special sub-vertical conveyor, the glass in transit is inspected and validated.
Finally, the laminated auto glass is unloaded and placed in special racks.
