Meta-Lax® Vibratory Stress Relief Equipment from Bonal Technologies, Inc. - meta-lax-logo

Technology Pioneered in 1969

The Proven Alternative to Heat Treat Stress Relief

United States Department of Energy seal

Meta-Lax is a proven substitute for 80% to 90% of heat-treatment stress relief in metal-working applications. It improves the inconsistencies of the previous resonant-vibration technology by using more efficient, more consistent "sub-harmonic" vibrational energy, which is the optimum vibration stress relief frequency.U.S. Department of EnergyRead Article Here

Meta-Lax® Vibratory Stress Relief & Weld Conditioning Equipment & Technology Succeeds Where Others Fail

Perfect Welds
After several attempts at welding HY-90 “T” bar Bonal’s Meta-Lax technology was called on and the “T” bar was welded perfectly the first time. Lyman Martin
North American Shipbuilding
Tight Tolerances
We’re always working with very tight tolerances, if there was any sacrifices in quality we’d know it. But our results with Meta-Lax have been just excellent. Gary Aalbers
Aalbers Tool & Mold
Increased Life
Using the Meta-Lax process on crankshafts increases their life from a 10 race average to 30 races! Gordon Jennings
Paul Pfaff Enterprises
Quality Control
Every weldment is now either Meta-Lax weld conditioned or stress relieved in-house for quality assurance. Jim Amos
Detroit Tool
Consistent Results
Meta-Lax has been very beneficial to NASA and is used frequently. Gerald Miller
NASA Langley Research Center
Reduces Scrap
The results were astounding. We saw our scrap rate go from 50% to 0 and stay there. Tim O’Connor
U.S.Army - Watervliet Arsenal

Meta-Lax® for Vibratory Stress Relief

Meta-Lax is the world’s most consistent vibratory stress relief for metal structures. The patented sub-harmonic Meta-Lax process is the only vibratory stress relief process that is consistently effective in comparison to heat stress relief. In fact, Meta-Lax consistently achieves equal to or better results than heat stress relief. In short, Meta-Lax works and is reliable!

The SUB-harmonic energy level is the key to the tremendous success of the Meta-Lax vibratory stress relief process.

Meta-Lax is a patented vibration stress relief process which according to the US Dept. of Energy is a “proven substitute to 80-90% of heat treat stress relief applications yet saves 65-95% of the time and cost in doing so without sacrificing quality!”

Meta-Lax® for Weld Conditioning

Meta-Lax Weld Conditioning will relieve the heat stresses as they are being introduced during weld solidification. This procedure produces several desirable benefits for the weld metal and the heat affected zone including eliminating the need for post-weld stress relief.

Two major benefits are the minimizing, if not totally eliminating, weld cracking and weld distortion. Other benefits include welding faster by increasing amperage which also allows deeper weld penetration. Metallurgically, Meta-Lax Weld Conditioning produces a finer, more uniform weld grain structure, thus improving the weld's mechanical properties and ultimate fatigue life.

Weld ductility, in particular, is increased as much as 400% over a non-weld-conditioned weld!

If NASA Trusts Us, You Should Too

“Since we began using Meta-Lax, we have experienced the ability to hold dimensional tolerances on weldments and machined parts as never before.  … I think of Meta-Lax as an extra trick up by sleeve for a higher quality product.”  NASA – Langley

“We use Meta-Lax about 50% of the time for stress relieving and 50% for weld conditioning.  The system is used on fixtures and flyaway parts, from all sorts of shuttle support fixtures and tooling to shuttle landing gears and wheels.”  NASA - Dryden
