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 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)

Glass processing and imprinting

Cutting

Scoring and breaking with hard metal wheels inside our CNC-systems as standard procedure
Water jet cutting for elaborate outlines or cutaways
Drilling of openings

Surface processing

Etching: Instead of the standard glossy surface, we offer etching for creating a satin-finished “Antiglare“ surface
Coating/tempering: The application, thermical evaporation deposition, or sputter deposition of layers of Antireflex (AR), Anti-Smudge (AS), or Anti-Fingerprint (AF) reduces reflections and improves the appearance
Sanding and polishing: Applying a reccess as a finger guide and restoring glossy areas, for example for camera lenses

Edge processing

Milling and trimming as lined-, beveled-, or C-cuts
Polishing for glossy side surfaces

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
