  • Microelectronics
  • Optoelectronics
  • LEDs, medicine
  • R-axis, A-axis configuration
  • 2,4,5,6,8-inch cylinders
  • Optimized cylinder cutting program
  • High crystal growth rate – 83 kg boule - in 15 days

We have achieved 55% of using of 83 kg of boule for cutting suitable blanks of 2 ”and 6” inch cylinders.
Total length for 2 ”blanks 5345 mm.
The annual total gross output of 2 ”cylinders (TIE) can reach 100,000 mm).
