Crestline Factory 26

• 374 employees
• Continuous production on 3 shifts
• 1 million parts per month
• 100 million annual sales
• 30 years experience on average
• Employment peaked at double its
• current status

Shuttle Bearings

• Bearings in the shuttles actuators are expected
  to give off unique sound prior to failure
• Monitoring sounds given off by different shuttles
  to discover bearing wear
• Predicting failure of the bearings will help to
  end production interruptions and down-time

Silkscreen Tear Detection

• Silkscreen machine
• applies paint, trademarks,
• antennas, and defroster
• lines to glass
• Screen tear results in
• excessive application
• of paint, and tracking of paint onto assembly
  line components
• Determine screen tears, and shutdown system
  immediately
• Filtering out different frequencies until only
  the screen tear remains

5
Temper Particle Check

• Temper is measured by breaking and counting
  various size glass particles
• Camera takes images of the particles and relays
  to computer
• Software is used to count particles
• Re-programming the software will enable PPG to
  make more accurate counts

6
Scratching During Stacking

• Automated machines stack and unstack glass
• Scratching occurs occasionally
• Contaminated glass stacks going through the
  line waste time, supplies, and most importantly,
  money
• Acoustical detection of scratching can prevent
  contaminated stacks from further productions
  processes

In Conclusion

• Acoustics will be the major focus in improving
  production and quality
• GoldWave software is used to do all sound
  discovery, monitoring, and warning
• Predicting and preventing interruptions will
  decrease down-times in production
• When completed, improving quality and
  productivity, and decreasing down-time will help
  PPG AutoGlass stay on the leading edge of the
  auto-glass industry
