The science of strength: why chemical tempering and TK ovens are transforming glass processing

Glass is one of the world’s most versatile materials, but its inherent fragility often limits its application. Enter chemical tempering, a sophisticated process that enhances glass strength, making it indispensable across modern industries. TK S.r.l., a leading Italian manufacturer, is pioneering this field with its TK Chemical Temper ovens, and have just launched a new, detailed 3D video to give the world a realistic look inside this technology.
Understanding chemical strengthening
Chemical tempering is a highly advanced method of strengthening glass, fundamentally different from the more common thermal tempering. The process involves an ion exchange at the glass surface, typically achieved by immersing the glass in a molten salt bath at 450°C.
The advantages
Chemical tempering offers crucial advantages that make it the superior choice for specific applications, like:
- Thin glass treatment: it is the only viable method for strengthening very thin glass (up to 0.5 mm), which would warp or break in traditional thermal processes
- Complex shapes: it can treat glass with complex, non-planar shapes without distortion
- Optical clarity: the process does not alter the optical properties of the glass
- High strength: it can achieve higher strength levels than thermal tempering, making it ideal for automotive, architectural, optical, military and electronics sectors.

Showcasing precision: TK Chemical Temper Ovens
TK’s ovens are designed and produced entirely in Italy, representing the highest standards of Made in Italy engineering and craftsmanship. TK has just release a new 3D video dedicated to their TK Chemical Temper ovens, providing a clear illustration of the technical specifications that define their quality.
A new era of transparency and training
The launch of the new 3D video marks a significant step in TK’s commitment to innovation and customer service. the goal is to move beyond static documentation and offer a new level of transparency and understanding.
By offering an “inside-the-machine” view of the complete chemical tempering cycle, TK is effectively turning a complex industrial process into an accessible visual demonstration. This powerful sales and training tool allows TK to clearly communicate the technical advantages—superior quality, efficiency, and safety—that their ovens deliver to glass processors in over 70 countries.
Coupled with existing remote support systems like TKonnect 4.0, the video reinforces TK’s dedication to providing tailored, high-performance solutions and solidifies their global position as a leader in glass processing machinery.
