Measuring parts is important — but measuring alone is not enough. A supplier can pass final inspection but still leave you exposed if the production process itself is unstable.
At SPI, we embed Statistical Process Control (SPC) into every batch:
Cpk ≥ 1.67 for CTQ features — proving our process is not just “capable” but comfortably within spec.
Real-time control charts — operators and engineers see variation trends before non-conformance occurs.
FAI (First Article Inspection) — full dimensional layouts on pilot runs, documented in AS9102 format.
PPAP Level 3 — for automotive customers requiring full control plans, process flows, and capability studies.
Gauge R&R — ensuring that our measurement systems themselves are consistent and repeatable.
This proactive control means no surprises at mass production scale.

Global buyers need more than supplier promises — they need alignment with recognized standards.
ISO 9001:2015 – foundation for documented quality systems.
IATF 16949 aligned – automotive requirements including PPAP, APQP, and SPC.
AS9100 ready – aerospace workflows with full traceability and FAI compliance.
RoHS/REACH compliance – verified material certificates for EU/US markets.
Calibration traceability – all equipment tied to national metrology standards.
Every project is delivered with the documentation customers require — whether it’s a simple CMM report for a prototype, or a full PPAP package with MSA studies for automotive production.

One of the biggest frustrations in global sourcing is lack of visibility. At SPI, we eliminate this uncertainty by building digital traceability into every stage of production — from incoming material to final shipment.
Material registration – Every lot is logged with supplier, heat/batch number, and material grade.
Incoming inspection – Dimensional checks and material testing validate EN / ASTM / JIS equivalency.
Certificate validation – Material certificates are verified and archived.
Storage control – Approved materials are stored in designated zones, linked to job orders.
Process planning review – DFM risk analysis before machining.
Manufacturing process sheet – Defines fixtures, toolpaths, checkpoints, tolerances.
Approval workflow – Engineering sign-off required before production launch.
Process inspections – Key dimensions verified during machining runs.
SPC monitoring – Real-time control charts ensure Cpk ≥ 1.67 on CTQ features.
On-floor records – Operators log inspection results and corrective actions.
CMM inspection reports – Hexagon 3D CMM provides full dimensional layouts.
Balloon drawings – Features numbered and linked to inspection results.
Final inspection package – Includes roughness, SPC charts, Gauge R&R data.
Visual inspection – Every part undergoes cosmetic review with 6-direction photos archived.
Photo proof of packaging – Crate marks, inner protection, ESD/VCI recorded before shipment.
Digital data archive – All production + inspection data scanned & stored securely.
Retention period – Records maintained for at least 5 years for full traceability.
With every order, SPI delivers not just parts, but a complete quality evidence package:
Material certificates (EN / ASTM / JIS validated).
CMM dimensional reports with ballooned drawings.
SPC charts proving process stability.
Visual inspection photos (6 sides per product).
Packaging photos with crate/label proof.
Archived data traceability for 5 years.
| Aspect | Typical Supplier | SPI Approach |
|---|---|---|
| Inspection Capability | Calipers, micrometers, random checks | Hexagon CMM, Profilometer, Coaxiality Tester — full inspection + sampling |
| Process Control | Relies only on final inspection | Embedded SPC monitoring, Cpk ≥ 1.67, real-time alerts |
| Documentation | Basic inspection sheet | FAI (AS9102), PPAP Level 3, CMM reports, SPC charts, material certificates |
| Complaint Handling | Rework + explanation | NCR workflow, 8D root cause analysis, permanent corrective action |
| Traceability | Weak batch-level records | Full chain: material cert → work order → QC report → shipment proof |
| Delivery Assurance | Experience-based | Triple guarantee: inspection report + photo proof + material certificate |
| Industry | Customer Pain Point | SPI Solution | Outcome |
|---|---|---|---|
| Aerospace | ±0.002 mm tolerance; strict FAI audits | Hexagon CMM + AS9102 package | Passed OEM qualification on first try; 3 weeks saved |
| Automotive | 120,000 pcs/year; PPAP required | Cpk ≥ 2.0 + PPAP Level 3 | Customer secured long-term OEM contract |

We don’t just rely on final inspection. During machining, our team runs SPC monitoring and checks Cpk values so we can catch variations before they become non-conformances.
Every shipment comes with a full set of records — CMM reports, balloon drawings, 6-direction part photos, and packing proof — giving you clear evidence of compliance.
If an issue arises, we log an NCR and follow the 8D process. That means not just rework, but root cause analysis, corrective action, and long-term prevention.
Your CAD files remain safe: encrypted transfer, NDA signed within 1 business day, and archived securely without cross-project sharing.
Q1: How does SPI prove precision tolerance in CNC machining?
We validate defined features down to ±0.002 mm using Hexagon 3D CMM and certified gauge blocks. All dimensional data is included in ballooned drawings and digital reports for full traceability.
