The Manufacturing Process Used For Auto Glass Toronto That Makes Windshields Unique

 When some car owners are faced with the need for repairing or replacing their windshields, the quote for these services make them believe they are being swindled. Most will settle for the cheapest service providers some of whom use substandard auto glass Toronto. The seemingly high costs associated with windshields is partly because of their intricate manufacturing processes. Below are tidbits on this process.

Mixing of ingredients

First, water is mixed with soda ash, dolomite, limestone, cullet, and silica sand in a refractory tank at high temperatures and melted. The resultant molten mixture is then transferred to a float chamber from whence a long molten glass sheet is transferred to a furnace where it is gradually cooled. This cooled glass sheet forms the raw glass that will be used to make a windshield.

Shaping

After cooling, the glass is cut into different dimensions with a diamond cutting tool before shaping and tempering. Tempering involves the placement of the raw glass sheet into a mold with the manufacturer’s desired shape, then heating it until soft but not melted. As it sags into or on the mold, the glass is cooled quickly using cold air. Tempering hardens and strengthens the auto glass Toronto.

Sandwiching between PVB layers

In the last manufacturing step, tempered glass is placed between two thin layers of PVB {poly-vinyl butryral} before being heated. This step results in a transparent PVB layer that fuses with the glass sheets to make laminated safety glass. PVB makes your windshield shatterproof since it holds the glass shards in case of a collision.

The above steps are undoubtedly labor and cash-intensive for manufacturers. This means that most of the costs are passed onto the eventual user who is the car owner. Even so, the extensive manufacturing process guarantees that car owners have the best and safest auto glass Toronto option for their windshields.
