Excellent start of production on 18th August 2014 of GELI GmbH Ilmenau

Only a few weeks after the assembly of the single-pane safety glass (ESG)-oven and of all periphery machines on 18th August 2014 the serial production of (ESG) plates could be initiated. After just a few days of pilot production all technical parameters for the production of (ESG) were achieved to the satisfaction of all those involved.

Applied Ceramic Labelling

Applied ceramic labelling offers a multitude of design options for glass, especially for flat glass. In the printing process, water-soluble paint is directly printed onto the glass pane through an extremely fine piece of mesh (screen) using specially engineered installations. Subsequently, drying of the screen-print takes place in downstream furnaces. During this process the glass is tempered and at the same time the paint is being baked on in this special type of tempering (ESG-)furnaces.

Advantages of screen-print on flat glass:

  • Permanent baking of paint after tempering
  • Perfectly suitable for in-door or out-door purposes
  • Printing of flat glass panes from 4 up to 100 mm
  • Sunlight resistant, scratch and abrasion-proof
  • Finishing as insulation glass is possible

Fields of application in series production

Special fields of application due to multiple design options for flat glass:

  • Facades, complete glass installations and glazed out-door balustrades
  • Bathroom furniture, shower enclosures, panes for counters or in-door refrigeration units
  • Maximum pane size for screen-printing: 1,800 x 2,500 mm
  • Minimum pane size for screen-printing: 400 x 300 mm
