Introduction to Vibration Aging Technology
Vibrating Stress Relief (VSR) technology, known internationally as such, aims to induce resonance in the workpiece being treated through a vibratory stress relief device. This resonance transfers a certain amount of vibration energy to all parts of the workpiece, causing microscopic plastic deformation – the distorted crystal lattices gradually return to a balanced state. Dislocations re-slide and become pinned, thereby eliminating and equalizing residual stresses within the workpiece, ultimately preventing deformation and cracking during processing and use, ensuring the stability of the workpiece's dimensional accuracy.
Vibration Aging Technology Application Range:
Vibratory aging is suitable for castings, forgings, and welded parts made of carbon structural steel, low-alloy steel, stainless steel, cast iron, non-ferrous metals (copper, aluminum, zinc, and their alloys), as well as machined parts thereof.

Vibration Aging Process:
1. Pre-vibration Treatment: The equipment automatically identifies the resonance peak of the workpiece, stores the pre-vibration a-n process curve, and the analysis program determines the excitation frequency. The process and curve will be displayed on the LCD screen.
2. Time-sensitive Processing: The equipment performs automatically, determines the processing time based on different workpieces, and stores the a-t process curve. The process and curve are displayed on the LCD screen.
3. Post-vibration Processing: The equipment automatically scans the processed workpiece after vibration and stores the post-vibration a-n curve. The process and curve will be displayed on the LCD screen.
4. Printing Process: Print out the a-t, vibration pre-a-n, and vibration post-a-n curves for comparison, assessment, and record-keeping.
