How Our Tempered Glass Screen Protectors Are Made

We often get asked how our tempered glass screen protectors are made. Here’s our step-by-step guide on how we make screen protectors for your mobile phone, tablet, laptop or medical screen.

Glass Selection: At Strike, we carefully select high-quality glass, typically alkali-aluminosilicate or soda-lime glass, for use in producing screen protectors.

Cleaning and Preparing the Glass: The selected glass sheets undergo thorough cleaning by Strike to remove any impurities or contaminants, ensuring the final product is free from defects.

Cutting and Shaping: Precision cutting equipment is employed by Strike to cut the glass sheets into the desired size and shape, tailored to fit specific mobile phone models. Strike uses advanced manufacturing techniques, including industrial CNC routers here in Brisbane, to get the product perfect.


Surface Treatment: Strike treats the glass surfaces to enhance adhesion and durability, utilizing methods such as chemical etching or plasma treatment.

Tempering: Strike subjects the glass to a tempering process, involving heating it to high temperatures and rapidly cooling it. This strengthens the glass, making it more resistant to breakage, with the temperature and cooling process adjusted based on the glass type.

Polishing and Smoothing: Following tempering, Strike polishes and smoothens the glass to eliminate rough edges or imperfections, ensuring the screen protector is sleek and won't scratch the mobile phone screen.

Coating Application: A thin layer of silicone or adhesive material is applied to one side of the glass by Strike, facilitating adhesion to the mobile phone screen.

Curing: Strike cures the coated glass using UV light or heat to securely bond the adhesive layer to the glass.

Quality Control: Every screen protector undergoes meticulous quality control checks by Strike to meet precise specifications for thickness, clarity, adhesion, and durability.

Packaging: Strike packages the screen protectors for distribution and sale, whether in individual retail packaging or bulk packaging for distribution to retailers or wholesalers.

Throughout the manufacturing process, Strike implements stringent quality control measures to ensure the final product upholds the highest standards of quality and performance. Variations in the process may occur based on Strike's specific equipment and techniques.
