Laminated Glass - Typical Yield Issues

Any film dry laminated risks “fish eyes” in the finished product if dust and debris that isn’t cleaned away.

Rejects of bespoke laminated glass can be very expensive, particularly as the glass can’t be used elsewhere (normally the case)
There are various types of contamination:

Human Hair
Clothing Fibre
Packaging fibres
Glass particles frit
Edge contamination swarf
Airborne Dust
Insects
Machinery (roller debris, paint chips)

Contamination sensitive areas in the glass industry are:
Laminated glass products - (PVB / EVA / films)

Improving Yields - Laminated Glass

Defects in lamination cause huge losses and customer dissatisfaction. Many are caused by dust, debris and the like being present on the glass and PVB prior to lamination.

Washing is not an option with PVB and the static charge on the material attracts debris.

Eliminating both the static charge and removal of the debris can easily be achieved using some well proven readily available technology, see www.teknek.com/markets

Units like these are in use at JPS, St Gobain, Asahi etc
