Forelspa is the best glass manufacturer in Italy. In bending machine, we got significant change. Forelspa is the thousand year old Venetian glass making tradition. The concept was very innovative when we manufactured the first automatic double-glazing lines. The plastic deformations can be not developed by that glass and it is sensitive to surface imperfections their density per unit square use as a capacity index for the material to resist tension stresses.
The point of crack initiation has been demonstrated which is not necessary coincide with that of maximum nominal tension stress. Bending glass is a process which is made on tempered glass. Two sheets of tempered glass are involved in the process in overlying relation and positioning a containment barrier such as vinyl sheet over the adhered unit. If you want desired shape, you have to fracture the glass and unit manipulated. When the adhesion has already set, the vinyl is removed.
