Stress Relieve Metal by Relaxing Residual Stress Using Vibration Energy

Thermal stress relieving is costly in terms of time and energy.  It may take hours or days using a furnace and furnace time consumes large amounts of expensive fuel.  The Meta-Lax process relieves thermal stress within metal components by using nondestructive, highly efficient sub-harmonic vibrations to prevent distortion and cracking.

Metal-Lax stress relieves in minutes.  In the Meta-Lax (metal relaxation) process, the operator clamps a force inducer (vibrator) onto the object and, using instrumentation that measures vibratory amplitudes of the atomic lattice, determines the present harmonic frequency curve.  The curve represents the "false" harmonic frequency of the stressed metal.  After the force inducer vibrates the metal for about 20 minutes at a frequency corresponding to one-third of the height of the stressed harmonic amplitude, the harmonic frequency permanently shifts.  The new curve is a true reading, indicative of the metal's non-stressed state.

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 energy, which is the optimum vibration stress-relief frequency.  This process treats a wider variety of work pieces with a versatile portable unit and yields results much more quickly than conventional, stationary heat-treating furaces.  Hours or heat-treating become minutes with the Meta-Lax process.

Commercialized in 1991.  Now approximately 1300 units are currently operating in the United States with an estimated payback time of 6 to 9 months.  Computer controlled systems and manual systems available plus a range of force inducers to match your product weights and sizes.
