What is The Different Between Hot-Bend and Cold Engraved Tempered Glass

What is hot-bend tempered glass screen protector and cold-engraved tempered glass screen protector?

Nowadays, the 3D curved tempered glass we know have two types:

Hot-bend and cold-engarved tempered glass, but how to select the suitable one for our mobile phones?

​

Do you know the different between hot bending and cold carving? From the price, it can be seen that hot bending tempered glass is more cheaper than the cold carving tempered glass? But why?

The same is the tempered glass screen protector, with different produced technology, the effect of the tempered glass will be different. Hot-bend tempered glass screen protector is softened by heating and then formed in a mold, and finally annealed, and the yield is higher than cold carving tempered glass.

The cold-engarved tempered glass is carefully carved by the CNC machine, which has a stronger of craftsmanship and a higher quality.

The tempered glass screen protector adopts the real screen opening mode, with the whole high-quality cold carving glass, precise opening, accurate scale reduction, and the rounded corner design of the 3D surface, so that the body curvature and the surface of tempered glass is perfect fit the phone lcd screen, the integration is stronger, just like the original phone. But cold carving tempered glass has its disadvantage. Due to the deformation during the tempering process, after the finished tempered glass screen film is formed, it is easy to cause poor exhaust/unstable and difficult to exhaust.

The hot-bend tempered glass screen protector is mainly used to make a large curved edge tempered glass, the advantage of this technology is that the curvature of the curved surface is large and beautiful.The disadvantage is that the product has no texture overall, the hand feeling is not good, and it is easy to scratch hands.
