In-house glass processing

Glass processing

We can glass

We know how. Glass is a fascinating, versatile and durable raw material - and with now over 25 years of experience, we have developed a deep understanding of this material.

Free contours, different edges and polishes, cuts or break-throughs - in our modern glass machining centers we manufacture your glass solution with passion and enthusiasm. Special machines and the latest technologies simultaneously enable high quality standards with the greatest possible automation at the production site in Germany.

Our employees are known for their curiosity and commitment - again and again we push the boundaries of mechanical glass processing, supporting intuitive user guidance and operation.

It all depends on the right glass

The types of glass available on the market differ in their chemical composition, production method and behavior during glass processing. In this context, not every glass is equally suitable for every application and for every type of installation.

We will be happy to advise you on which material is best suited to your requirements and design preferences.

In our glass processing, we can also process and finish almost all available glasses for the production of input systems.

It all depends on the right glass

Precise edges and razor-sharp contours

Glass processing requires experience, knowledge and a whole lot of sensitivity. Our employees have been knowing the processes and machines for years.

They actively contribute to the expansion and further development of the machinery. In addition to classic CNC-controlled processes, we work with state-of-the-art laser technology. This is where the future of glass processing lies, which is why we are also expanding our capacity in 2023 and investing in more promising laser systems.

For our customers, this means complete freedom for shape and contour, numerous variants for edge geometry and design, and more options for break-through. A new feature is the option of structuring the surface and thus designing specific cuts or haptic surfaces and guide aids.

For intuitive user guidance and creative freedom, we offer:

  • free, dimensionally accurate contour shape
  • polished or satinized edge in different grinding shapes
  • ground-in applications such as fingertip, wheel or slider
  • break-throughs in free form for mechanical components

Limitless Design

Light control

Maximum customization with our digital technology

After more than two years of process development in the field of digital printing, we are proud to further expand our reputation as a provider with the best print quality. This means that our customers always have the choice between different printing processes including their respective advantages or even a combination of both techniques to achieve the best result.

Color gradients and intricate textures that mimic natural materials such as wood or surfaces like roughcast. High contrasts with sharply defined edges are standard for us with today's technology and our know-how.

Variants for the OEM business with changing logos, consecutive numbers (for hotel rooms, for example), language variants in small quantities but also individual coding per piece are now state of the art. The best example is our EVYTRA SWITCH - here, individual icons are displayed for individual rooms or scenes, while each building or company has its own logo. Corporate design and current furnishing colors merge on request into a holistic design concept.

The right color matters

Normal glass and even special white glasses always have a green cast. The thicker the glass, the stronger this green tint is perceived and influences the effect of the colors through the glass. Our color sommeliers are able to detect even the slightest color gaps.

The inks and formulas used are adjusted accordingly so that we can produce any RAL and PANTONE color tone true to color despite natural glass discoloration - and always the same. Even changes in color density for lighting effects such as an individual alarm symbol, a softly illuminated surface or an integrated display can be realized with our EVYTRA printing processes.

Perfekte Haftung

Guaranteed long-lasting due to perfect adhesion

A decisive factor for the longevity of your products and above all a visual advantage over input systems made of plastic is the durability of the colors on glass. Because the design is applied to the back, it is permanently protected from external influences such as mechanical wear and tear, chemicals or environmental influences.

This means a challenge for the adhesion of the inks, which we have been mastering for decades. Conductive elements, components and the mechanical components necessary for assembly or installation exert tension or pressure on paints and glass.

What sounds simple requires extensive know-how and experience. Therefore, the formulations are mixed individually for each customer to suit their requirements. Already in our house, the colors are exposed to galvanic processes and high heat - a real endurance test and quality check in advance. The subsequently soldered components sit bombproof - for decades. Vibrations of machines or e.g. also in special vehicles but also strongly fluctuating basic conditions have no influence on the reliability of the sensor technology.

Superior Functionality for User Guidance and Feedback

User-friendly and intuitive control panels

User-friendly and intuitive control panels

Capacitive components are the basis for the development of touch solutions. Here, the user can perform an operation via a closed surface - without applying pressure.

Depending on the application and the information required, the combination of capacitive keys with a (touch) display offers enormous advantages. While key functions are always accessible and feedback is always visible, a display can be used to show changing data and graphics or more in-depth menu structures.

Even functions that are not used on a daily basis, such as a maintenance mode, are integrated intelligently in this way. We develop a customized system for your requirements - with individual information provision and user feedback and suitable for high mechanical stress. Immediately ready for use without long charging times, largely independent of temperature and light irradiation and with a higher and longer availability of components than standard displays.

Optimal usability through haptic and acoustic feedback

Pure touch solutions or industrial PCs have decisive disadvantages depending on the environment and application. While tablets or displays completely lack haptic feedback and often obscure information, industrial PCs and their peripherals are susceptible to contamination and mechanical damage or wear. In addition, both are often interchangeable standard solutions that are not optimally designed either in terms of their geometry or HMI concept.

Structuring of the glass surface, such as cuts in the shape of a fingertip or a slider, optimally supports the operator without losing the advantages of a closed glass front.

Attention-grabbing shapes such as a wheel are both an HMI and a design element, enhancing the product both visually and haptically. Special tasks require special solutions - especially in a noisy environment or when the user is dependent on blind operation such as setting machine parameters with visual control, our combination of mechanical buttons and switches paired with our smart technologies offers several advantages: Operation with clearly tactile feedback such as with a glass button with mechanical stroke, alternating illumination of individual symbols and status displays.

But classic feedback such as acoustic signals or tactile feedback can also be combined. Just exactly the optimal solution for every application.

Optimal usability through haptic and acoustic feedback

Smart lighting concepts make things easy for the operator

Design and printing technology provide the basis for optimal operator guidance. The targeted use of lighting effects such as flat or spot lights, for highlighting, different colors and different brightness gradations offer the possibility of feedback for a coherent UX concept.

Information that is not relevant can be hidden thanks to a "disappearing effect" and, for example, displayed at another time. This can be pure displays or complete buttons. Displays and 7-segment displays can also be seamlessly integrated in this way without disturbing the perfect overall appearance. So only the functions that are actually necessary become visible.

Misoperation is thus avoided and the (decision-making) stress for the user is reduced. Thanks to modern sensor technology, it is also possible to completely integrate the HMI into the environment, for example by having it switch from an (unlit) standby mode to an illuminated standby mode when approached. In addition to eliminating the often visually distracting status lights, this also reduces permanent energy consumption.
