Tempered glass is produced by heating annealed glass in a furnace to 620°C. Progressing from the furnace, the glass is rapidly cooled with jets of cold air, inducing compressive stresses to the surface while the center remains tensile.

Features:

1.Safety:Tempered glass is hard to break and it will shatter into small oval-shaped pebbles when broken

2.High strength:Tempered glass is three to five times stronger than standard glass 

3.Heat stability:Tempered glass also have excellent stability under large difference in temperature within 250°C

Processing Steps:

1.Choose high quality float glass and cutting

2.Drilling holes and polished edges

3.Washing glass sheets and tempering

4.Quality checking

Notice:  All work done on glass (beveling, cutting, bending,printing,etc.) must be done before tempering

Qct:

1. Tolerance test of sizes and thickness

2. Visual test of stain, bubble, chip,breakage,scratch

3.Impact and Particles test

4.CCC and SGS

Application:

Tempered glass is one of two kinds of safety glass regularly used in applications which standard glass could pose a potential danger. Tempered glass is widely used to make glass doors, curtain walls, partitions, elevator,showcase,furniture,home appliance,etc.
