Project Tips
Get lab-grade alloy verification running in your facility on day one
1. 5-Minute Physical Setup
- Place on any stable workbench (vibration-dampening mat recommended for machining shops).
- Connect to 100–240V power + Ethernet/Wi-Fi for LIMS integration.
2. First-Time Setup (15 minutes total)
- Load factory alloy library (1,000+ pre-installed grades – AISI, DIN, GB, JIS, UNS).
- Run included 316L & Al 6061 calibration standards → system self-calibrates.
- Add your company logo once → every report is automatically branded.
3. Daily Workflow That Prevents Mistakes
- Operator scans barcode → selects part number → places component → presses “Start”.
- 30–60 seconds later → screen shows exact chemistry + pass/fail vs spec.
- Auto-generates PDF certificate with photo of tested spot (perfect for AS9100/ISO audits).
4. Pro Tricks by Application
| Application | Best Practice |
|---|---|
| Incoming material inspection | Test every heat lot in 60 sec before releasing to production |
| Weld & heat-affected zones | Use 3 mm collimator + “coating mode” to ignore surface oxidation |
| Finished machined parts | 1 mm spot size for tiny features; no surface prep needed |
| Scrap sorting | Create custom “pay grades” – instantly separate 304 vs 316 vs Inconel |
| Coating/plating thickness | Switch to thickness mode – measures Zn, Ni, Cr layers in microns |
5. Zero Maintenance Reality
- Weekly: wipe sample window with alcohol.
- Yearly: free remote health check from Napco.
- Tube life: 10+ years in normal industrial use.
Overview & Challenge
The Hidden Crisis in Alloy Manufacturing & Material Verification
For decades, factories, metal suppliers, aerospace contractors, and scrap yards relied on slow, expensive, and often destructive methods to verify alloy composition and quality:
| Traditional Method | The Real-World Pain Points (The Challenge) |
|---|---|
| Wet chemistry / lab analysis | 3–10 days turnaround, high cost per sample, destroys the part |
| Spark OES (Optical Emission) | Requires perfect flat surface, burns the material, not suitable for finished parts or field use |
| Portable spark guns | Slow, needs argon gas, surface preparation, damages high-value components |
| Magnetic & eddy current tests | Only works on ferrous, cannot quantify exact chemistry or detect trace elements |
| Outsourcing to external labs | Delays production, shipping risks, $50–300 per test, no real-time decision making |
| Visual inspection + certificates | Easily forged supplier documents → catastrophic failures (wrong grade used in aircraft, valves, etc.) |
Daily consequences companies suffered:
- Production lines stopped waiting for lab results
- Wrong alloy shipments accepted → millions in rework or recalls
- Failed audits and rejected parts due to missing PMI documentation
- Safety incidents from undetected off-spec materials in critical applications
- Scrap yards losing 5–15% profit by mis-sorting high-nickel or titanium alloys
