Vacuum rings are most commonly used to manufacture automotive laminate windscreens. To create laminate glass, two pieces of glass are bonded together with an enforced layer of PVB in the middle. This increases the compressive strength of the glass while also ensuring that the glass does not shatter if broken. This is the key characteristic of automotive glass which helps to increase safety for passengers.
Laminate glass is commonly used for windshields on cars, trucks and buses but this market is expanding to include rear glass and side glass. Demand for increased safety and security drive this change, in addition to advances in infotech and noise reduction.
