Closed-Loop Wall Thickness Control

Constant press duration

Our solution controls the individual phases of the pressing process. The patented procedure records how long the plunger stays in the glass and then regulates the pressure and time accordingly. Control of the press duration, i.e. the time the plunger remains in the glass, ensures repeatable wall thicknesses. This is a critical quality feature in hollow glass production.
