Toughening
Toughened or tempered glass is a type of safety glass. Toughened glass is made by heating annealed (float) glass uniformly through a furnace to temperatures exceeding 600 C. The annealed (float) glass is then transferred to the quenching chamber of the furnace where it is rapidly cooled.
This process increases the compression forces on the surface and the tension forces inside the glass, which gives toughened glass four to five times more strength than ordinary annealed (float) glass of the same thickness, combined with much greater resistance to impact.

Heat Soaking
Toughened Glass can sometimes spontaneously break; the reasons can be many. The main cause determined by leading experts are that there are microscopic traces of Nickel Sulphide (NiS) inclusions within the glass which can be activated during the heating process in producing tempered glass.
At Tough Glass the heat soak treatment is a quality control process carried out by placing the toughened glass panels inside an oven chamber and subject the glass to a prolonged temperature up to 270°C in a controlled cycle to accelerate nickel sulphide expansion. This causes glass containing nickel sulphide inclusions to break in the heat soak chamber, thus reducing the risk of potential breakages after installation.

Heat Strengthening
Heat strengthened glass is processed through the furnace (similar to toughened glass) but is not safety glass. Heat strengthened glass is approximately 2 times stronger than ordinary annealed. Heat strengthened glass, when broken will break into large pieces and will not shatter into smaller pieces like toughened glass.

Automated Cutting
Our LISEC cutting tables ensure quality and accurate flat cutting. With a series of pneumatic lifting timing belts for the loading of the loader and the unloading in the glass processing area, allows the possibility of implementing any complex cutting scheme including straight cut and shape cut options. It is also possible to adjust the cutting parameters directly from our computer systems and the configuration can be memorised with association to the type of glass. This way the cutting quality is excellent and consistent, which means we maintain a good glass breakout quality.

Water Jet
Our Waterjet cutting table is designed and engineered to ensure maximum accuracy, reliability and durability.
This technology uses extremely high-pressure water and garnet to focus ordinary water through a jewel orifice into a fine stream. This stream carries powdered garnet, which can cut through almost any material. Glass can be cut quickly and cleanly, without heat.

CNC
Our Intermac CNC’s 28 automatic tool holders ensure we have the right tool for the right job, and the glass is processed seamlessly once loaded onto the bed. The Master 43 is a 3-axis work centre that can fully process glass to a high-quality finish. Our laser device detects geometric templates to ensure accuracy when processing on the CNC. Cut to size glass placed on the CNC’s can be fully processed from start to finish ready for toughening.

Arrising
Tough Glass utilise an automated glass arising machine used to arris both shaped and square glass on all edges. The KSR enables us to arris and wash the glass after cutting. Providing an extra quality inspection point before further processes are added to the glass if required. Arrising the glass all round also ensures safety when handling glass throughout our factory through to deliver to our clients
The KSR also enables us to accurately arris all performance laminated glass to mitigate risk of thermal cracking due to poor edgework.
All glass requiring toughening must also have a minimum arrised edge to prevent breakage during the toughening process.

- Glass is arrised manually using a minimum of 180 grit belts if glass is outside of KSR processing capabilities
Polishing
The presence of 3 diamond grinding wheels on our straight-line edger allows us to work glass and provide a quality polishing service. The cerium oxide felt in the last position ensures an excellent brilliant finish for the profile. Quality is ensured at all stages of production with automatic regulation of the polishing wheels when the glass thickness changes.
