Vibration stress-relief in practice Meta-Lax American technology
The effect can be measured, the result appears immediately, the return of investment (ROI) is less than a year!


Meta-Lax treatment was developed 20 years ago in the USA by Bonal Technologies, Inc., supported by NASA and the U.S. Department of Energy.

The treatment is still new in Europe
Vibration stress-relieving (Meta-Lax technology), equals to thermal stress relieving, can be used on metals:


  • Before and after machining
  • During and after correction welding 
  • During and after construction welding
  • For quality control of incoming goods
  • For quality insurance
  • For regular stress relieving of die
  • To eliminating thermal stress occurring in tools and equipment while in use

Benefits of vibration stress relieving:

  • No distortion
  • Part of working process
  • Eliminate one rough cut
  • Applied before wire cut machining, no deformation in the parts
  • No micro cracks
  • Cost of treatment 90% lower than that of thermal treatment  
  • No change in material solidity
  • Portable equipment
  • One complete mould can be treated at the same time
  • More parts may be treated at the same time
  • No scal
  • 41% less machine time

Benefits during correction welding of tool parts:

  • No micro cracks
  • No deformation
  • No need to preheat whole metal. Local heating, on a significantly lower temperature is enough.
  • Minimum 300% longer fatigue life
  • Reduced porosity and undercutting
  • Stress relieved workpiece after welding

Benefits during equipment manufacturing, while welding (weld-conditioning):

  • 84% less distortion
  • Improved mechanical properties-ductility and impact
  • Deeper weld penetration
  • Same quality with lower Amperage, easier Control of Weld
  • Reduced undercutting
  • Reduced rework and scrap
  • Homogenous texture in joint
  • No micro cracks
  • No inclusions
  • No size or weight limitation
  • No thermal stress, material is stress relieved by the end of the process
Further characteristics:
  • Success of treatment (stress relieved condition) is represented graphically
  • Duration of stress relieving procedure: maximum 1 hour
  • Maximum weight of treatable workpiece: 18 tones  
  • The equipment is portable
