Realisizing individual HMI glass touch panels simply and effectively

HMI glass touch panels with projecting capacitive touch screens (PCAP, PCT) are innovative and high-grade input devices that are resistent to numerous chemicals, scratches, staining, and vandalism. Additionally, they allow for the integration of further elements – for example PCAP buttons, backlit displays, and many more.

Selecting the right glass

HMI glass touch panels use technical plate glasses manufactured by using the float glass technique. We offer a selection of different glasses and plastics:


Glasses

  • Soda Lime: Lime natron plate glass is the most commonly used glass for HMI glass touch panels
  • Soda Lime Low Iron: Lime natron glass with a low percentage of iron. For ideal transparency and without any green cast
  • Aluminosilicate Glass: Extremely sturdy due to its high percentage of aluminium and matched tempering. Also known as Gorilla®, Xensation®, or Dragontrail®
  • Borosilicate Glass: Exceedingly resistant to chemicals and very temperature-resistent as a result of its high percentage of boric oxide


Plastics

  • PMMA: Polymethyl Methacrylate, also known as acrylic glass or Plexiglas®
  • PC: Polycarbonate with a low thermal expansion coefficient and a high resistance to breaking (shatterproof)

Take advantage of our in-house glass processing and imprinting facilities

Tempering

  • Chemical tempering for ideal mechanical stability, sturdiness, and flexural yield strength
  • Thermic tempering for the manufacturing of  thermally toughened safety glass


Imprinting

  • Organic two-component screen and pad printing for an extensive variety of colors
  • Ceramic burn-in printing for ideal adhesion and durability
  • Digital screen printing for an unlimited choice of themes
  • Translucent printing for “vanishing“-effect of LEDs and light sensors
  • Spaced lettering for the elimination of transparency

Benefit from a wide range of bonding types

  • Air bonding: Connection of components with double-sided, mostly carrier-free acrylic adhesive tape in the boundary areas
  • Black display optical bonding light: By adding additional optical filter screens we reduce internal reflections and improve blackness and contrast

Choosing the best touch technology

In addition to design, usability and serviceability are becoming increasingly important in order to differentiate products on the market. That is why our experts support you in the selection of optimal interaction and touch technologies, using both selected use cases and your defined environmental conditions. We offer:

  • PCAP/PCT: Projective capacitative glass or sheet touch sensors for continuous HMI front glasses
  • Resistive solutions: Screen/glass, glass/glass, or glass/screen/glass touch sensors for sturdy usability – also available as multi-touch and with zero-bezel design
  • Fine-tuning: Touch controller tuning ensures sensitivity, filters, and algorithms are perfectly suited to your use cases and environmental conditions

Our experiences with technical engineering and assembly are a big money and time saver

Count on a modern and intuitive GUI

We thoroughly examine, test, and optimize user interfaces (UI) to uncover obstacles in the usability and design all interactions as appealing and efficient as possible. Where it is useful, we will use established symbols and interactions, but we will also break new ground to give your users a unique user experience.

Trust in first-class mechanical engineering and industrial design
