Jovvi begins with Grade 5 titanium (Ti-6Al-4V) bar stock from ISO 13485-certified suppliers. Each batch includes a Mill Test Report (MTR) confirming:
Factory quality check: XRF spectrometer verifies composition on every bar before machining.
| Tool Type | Machining Process | Key Precision Parameters |
|---|---|---|
| Wrenches | 5‑axis CNC milling from forged Ti bar (or fully machined for custom sizes) | Jaw opening tolerance: ±0.05 mm; Parallelism: <0.1 mm |
| Screwdrivers | Swiss‑type CNC lathe for blade; milling for tip geometry | Tip concentricity: <0.05 mm; Blade straightness: <0.1 mm per 100 mm |
| Hex keys | CNC grinding from Ti wire (drawn to exact cross‑section) | Across‑flats tolerance: ±0.02 mm; Corner radius: <0.05 mm |
Coolant: Non‑ferromagnetic, recycled in closed‑loop system (zero discharge).
Machined tools undergo solution treatment + aging to achieve final hardness:
Resulting hardness: 38–42 HRC (wrenches, screwdriver tips, hex keys). Tested per tool batch (3 samples per 100 pieces).
| Process | Purpose | Method |
|---|---|---|
| Bead blasting | Matte finish, removes machining marks | Glass beads (100–200 mesh), 60 psi |
| Passivation | Restores oxide layer (corrosion resistance) | Nitric acid bath (20% HNO₃, 30 min, 50°C) |
| Laser marking | Permanent identification | “Ti ≥90%” + size + serial number (no paint) |
No coating – Jovvi does not apply titanium nitride (TiN) or any other coating that could hide a steel substrate.
Screwdrivers (blade + handle):
Torque wrenches (beam + spring + handle):
Ratchet handles (body + gear + pawl):
Every tool passes through a SQUID magnetometer (ASTM F3042):
| Inspection | Tool Types | Method | Pass Criterion |
|---|---|---|---|
| Dimensional | All | Laser micrometer | Within ±0.05 mm of nominal |
| Tip geometry | Screwdrivers, hex keys | Optical comparator (50×) | Corner radius <0.05 mm |
| Jaw parallelism | Wrenches | Feel gauge + CMM | Gap <0.1 mm at 10 N·m |
| Torque accuracy | Torque wrenches | Calibration stand | ±5% of reading |
| Visual | All | Magnified LED inspection (10×) | No cracks, pits, or machining burrs |
Packaging: Each tool placed in custom foam insert inside ESD-safe ABS case (no steel hinges – brass or plastic clasps). Case labeled with “JOVVI Ti – MRI SAFE – DO NOT MIX WITH STEEL TOOLS”.
Every Jovvi tool is laser‑etched with:
Certificate of Conformance included in each kit lists batch test results.
