Industrial Scenario

Silica sands are:

  • Storaged
  • Heated
  • Melted
  • Rotated and shaped
  • Cooled and solidified

Speed Production: 4 m/s – 24h/7d

Focus on problems

Small defects can cause big problems:

  • Broken final product
  • Contamination for pharmaceutical products
  • Economic losses for provider

Over than 40% of glass is discarded during quality checks Gerresheimer in 2014 has lost more than 10 millions of dollars for delivering of packages that don’t comply with the quality requirements of the customers

State of the art

Human Operator

  • Unconstant performance
  • Bad accuracy
  • Not objective evaluation
  • By sampling checks
