Thermal Toughening

Glass mouldings that have been subjected to a controlled heating and cooling process resulting in significantly increase resistance to mechanical and thermal stress.

Through the thermal toughening process, our precision glass mouldings can be used in applications where they are subjected to very rapid changes in temperature.

Chemical Toughening

Chemical toughening is used to enhance and strengthen glass to very high levels making them perfect for specialist applications such as thin walled items.

It involves an ion exchange reaction, which replaces sodium ions at the surface with bigger potassium ions, putting a thin layer of the surface into a high level of compression.
