Jovvi titanium wrenches (open-end, box-end, combination, and torque) are manufactured through a controlled process that ensures ≥90% titanium content and ends with permanent laser marking.
Raw Material:
Raw Material: Forged or machined from Grade 5 Ti-6Al-4V bar stock with certified ≥90% titanium content.
Manufacturing Steps:
| Step | Process | Quality Check |
|---|---|---|
| 1 | Forging or CNC machining of wrench blank | Dimensional inspection |
| 2 | Heat treatment (age hardening) | Hardness test (38–42 HRC) |
| 3 | Jaw broaching (box-end) or milling (open-end) | CMM measurement, runout <0.05 mm |
| 4 | Bead blasting (matte finish) | Visual inspection |
| 5 | Passivation (oxide layer restoration) | Corrosion test (salt spray) |
| 6 | Laser marking | Permanent mark verification |
| 7 | Magnetic susceptibility test (100%) | χ < 5 × 10⁻⁶ |
Laser Marking on Wrenches:
Location: Laser mark applied to flat face of wrench (non-contact surface)
Content: Size (e.g., “10mm”), “Ti ≥90%”, batch number
Additional marking for torque wrenches: N·m scale laser-engraved on beam
Torque Wrench Calibration Mark:
Each torque wrench receives a calibration date laser mark: CAL: YYYY-MM-DD. Re-calibration marks can be added over existing marks (laser overwrite is acceptable).
Quality Verification:
100% of wrenches pass through SQUID magnetometer
10% of each batch undergo torque testing to destruction (sample)
Factory note:
“Laser marking is applied after heat treatment and passivation – the mark is permanent and will not wear off during years of MRI service.”
