Laser crack off machine

Highlights in comparison to conventional score thermoshock process:

  • Processing of glass articles without mechanical contact
  • Bowl run out is avoided when processing articles with long thin stems and there is no waste as a result of glass breakage
  • So-called safety mouth rims, which are produced by melting, make grinding superfluous
  • Average quality glasses can be finished to choice without face grinding or chamfering
  • Required grinding can be reduced by up to 75%
  • A higher annual capacity of up to 25% is possible
  • Lower surface tension
  • Lower operating expenses of up to 10% per year
