The swiss company Interglass Technology AG developed a new technology for the manufacturing of progressive eyeglass lenses.

The revolutionary advantages: The new system produces high-quality organic progressive lenses quickly, highly economically and without material waste.

Technology  
System:
Fully automated system for production and surface treatment of eyeglass lenses, consisting of

  • molds cleaning station
  • molds store
  • casting unit
  • splitting unit
  • curing system
  • coating system (tinting, hardcoating, antireflex)

Casting Technology:
Monomer is casted in mold cavity. Shape of cavity represents outside shape of lens. Curing of lens by UV exposure within seconds.

Software:
Needs minimum personnel training. Order input by hand, via disk, CD, USB, or LAN connection. 

Software-Option:
Input and Controlling via ERP of customer.
 
Cycle time:
96 seconds per lens (average 90 sec)
  
Production time:
35 minutes uncoated, with coating approx. 60 minutes
  
Capacity:
300 lenses per 8h shift
  
footprint:
25 m²  

Standards:
CE, UL
  
Operators:
One per shift
  
Consumables:
Monomer (UV-curable Monomer Mid-Index LCM 118), usual consumables coating.
 
Tooling:
456 molds for basic design.
