A Controlled System, Not Just Inspection

Our quality management system integrates process control, calibrated measurement, and CAPA-driven improvement across every stage of manufacturing — ensuring stable, repeatable results for regulated industries.

DEK's quality system isn't just about checking parts at the end of the line. We embed quality controls into every phase of production — from incoming raw material verification through in-process monitoring to final outgoing checks. This documented approach covers IQC, IPQC, FAI, OQC, SPC, and CAPA, controlling dimensional accuracy, process stability, and inspection consistency across all production stages.
  • Process-Driven Quality

    Defined inspection plans, calibrated equipment, and documented procedures at every manufacturing stage.

  • Continuous Improvement

    CAPA-driven corrective actions and SPC monitoring ensure defects are eliminated, not just detected.

  • Full Documentation

    Every lot ships with complete inspection records, material certificates, and dimensional reports.

Five-Stage Inspection Flow

Every part passes through a structured, five-stage inspection sequence — ensuring dimensional conformance and process stability from raw material to finished component.

  • IQC

    Incoming Quality Control

    Raw materials verified against certificates. Dimensional spot checks and hardness testing on critical stock before release to production.

  • IPQC

    In-Process Quality Control

    Real-time SPC monitoring, tool wear tracking, and dimensional checks at defined intervals during machining operations.

  • FAI

    First Article Inspection

    Complete dimensional report on first production parts per AS9102 or customer-specified format. All critical features verified before batch release.

  • OQC

    Outgoing Quality Control

    Final inspection against drawing specifications using calibrated CMM and optical systems. Surface finish and visual inspection included.

  • CAPA

    Corrective Action

    Any non-conformance triggers root cause analysis and documented corrective action. Systemic improvements fed back into process controls.

Calibrated Inspection Capability

Our temperature-controlled metrology lab is equipped with high-precision measurement systems calibrated to NIST-traceable standards, supporting tolerances as tight as ±0.005mm.
