How We Guarantee Precision at Scale

DEK operates under controlled manufacturing processes with certified quality systems and documented inspection procedures to ensure consistent, repeatable results.

Our quality control system is built on the foundation of ISO 9001:2015, with additional compliance to AS9100D for aerospace-grade work. Every production run is governed by a documented quality plan that specifies inspection points, measurement methods, acceptance criteria, and record-keeping requirements.

From incoming raw material verification through in-process dimensional checks to final inspection and packaging, our multi-stage QC workflow eliminates cumulative errors and ensures that every part shipped meets your exact specifications—whether you’re ordering 10 prototypes or 10,000 production units.

All quality records are retained digitally for a minimum of 10 years, providing full traceability and audit readiness for your supply chain requirements.

Multi-Stage Inspection

Incoming, in-process, and final inspections at every critical stage.
Full Documentation

Inspection reports, material certs, and COCs provided with every order.
Real-Time Monitorin

SPC data and live machine monitoring reduce drift and deviation.
10-Year Record Retention

Digital records stored securely for full traceability and audit compliance.

Four-Stage Quality Control Process

Our structured QC workflow is applied to every order, from prototype to production, ensuring zero-defect delivery through systematic checkpoints.

1
Incoming Inspection

Raw materials are verified against material certificates. Dimensional, hardness, and composition checks confirm specification compliance before any machining begins.
2
In-Process Control

Critical dimensions are measured at defined intervals during machining. SPC monitoring detects drift early, and first-article inspection (FAI) validates each setup.
3
Final Inspection

Every part undergoes comprehensive dimensional and visual inspection using CMM, optical, and surface measurement equipment against the drawing's GD&T requirements.
4
Documentation & Release

Inspection reports, material traceability records, and Certificates of Conformance are compiled and delivered with every shipment for complete audit readiness.

First Article Inspection (FAI)

Our first article inspection process validates that the production setup, tooling, and programming deliver parts within specification before full-run production begins—saving time and eliminating scrap.

Inspection & Metrology Capabilities

Our quality lab is equipped with calibrated, industry-standard metrology equipment to verify every critical dimension and surface specification.

Coordinate Measuring Machines

High-accuracy CMMs with touch-trigger and scanning probes for 3D dimensional verification of complex geometries, achieving measurement uncertainty below ±1.5μm.
Optical & Vision Systems

Non-contact optical measurement systems for profile inspection, micro-feature verification, and surface defect detection on delicate or small-scale components.
Surface Roughness Testers

Contact and non-contact profilometers measure Ra, Rz, and other surface parameters to verify finish specifications from Ra 0.2μm to Ra 6.3μm.
Hardness & Material Testing

Rockwell, Vickers, and Brinell hardness testers confirm heat treatment results. XRF analyzers provide positive material identification on incoming stock.
