Bent tempered glass or bent heat strengthened glass is made of float glass which is firstly heated to the softening point and then bent to shape and finally cooled down rapidly by special facility.Bent glass is made of float glass which is firstly heated to soften point and then bent to shape by weight of glass itself or outside force, and finally cooled down.ZNG adopts advanced technology of synchronous roller shaping process. Model can be adjusted easily and flexibly. Bent glass produced by ZNG is of exellent apperance quality and good optical performance.
