Quality assurance

Our quality promise

Zero Compromise

Every part undergoes 100% dimensional, cosmetic, and functional checks.

Data-Driven

Real-time inspection reports with pass/fail metrics.

Risk-Free

Free rework or remake if standards aren’t met.

How Fiwok ensures defect-free CNC parts:

Core Quality Practices

We ensure quality by below aspects: Advanced metrology, traceable materials, and skilled teams. 100% inspection & downloadable QC reports.

Expert-Led Precision

AS9100-Trained Teams: 10+ years avg. experience in machinery parts & aerospace & medical part programming.
Tooling Excellence: Precision fixtures + tooling for ±0.01mm repeatability.

Cutting-Edge Verification

3D Metrology: CMMs (±0.005mm accuracy).
Surface Analysis: Roughness testers (Ra 0.4μm verification).

Full Traceability

Material Certificates: Mill test reports (MTRs) for metal/plastic.
Process Documentation: Step-by-step inspection videos/photos on demand

3-Step Quality Assurance Process

1. In-Process Inspection

Pre-Machining: Material cert verification (MTRs provided).

Mid-Production: Critical feature checks using:

CMM Machines: ±0.005mm accuracy

Surface Roughness Testers: Ra 0.4μm to 6.3μm validation.

2. Final QC

Full-Dimension Report: PDF/Excel formats with GD&T callouts.

Visual & Tactile Review: 10x magnifiers + calibrated gauges.

Functional Testing: Pressure, fit, or conductivity tests (on request）

Pre-Shipment Approval

Photo/Video Proof: Shared via email or client portal.

Packaging Audit: Anti-rust VCI, shock-resistant foam.
