ISO 9001 Quality Assurance & Precision Inspection

Every part is inspected, documented, and approved before it leaves our facility. No exceptions.

Six-step quality assurance

A structured, documented QC process applied consistently to every order - prototype or production run. For details on our equipment, see our inspection capabilities.

  1. 01

    Material certification

    We provide the Material Data Sheet or Material Certificate for every order on request. You always know exactly what material your parts are made from.

  2. 02

    Drawing review before programming

    Before any machining begins, 3D and 2D drawings are reviewed again for consistency. Any discrepancies between 3D model and 2D drawing are raised with you for confirmation - preventing costly errors downstream.

  3. 03

    In-process dimensional inspection

    Machined parts are compared against the 3D model. All tolerances marked in the 2D drawing are measured. Unmarked tolerances default to ISO 2768-mK as standard.

  4. 04

    Thread & bore gauging

    All threads are verified with go/no-go gauges. All tight-tolerance bores are measured with precision pin gauges. Tungsten steel gauges are purchased where required by specification.

  5. 05

    Geometric tolerance verification

    All geometric tolerances (GD&T) are measured. Where full dimensional verification is required, all dimensions are checked on a coordinate measuring machine (CMM).

    Inspection report & photos before shipment

    We send you the full inspection report and real photographs of your parts for approval before shipment. Parts are only shipped after your confirmation - giving you full visibility and control.

Dedicated quality professionals

Quality is not a final check - it is embedded throughout the production process by dedicated engineers at every stage.

Quality Engineer

On-site measurement

Responsible for verifying dimensional data of all parts at the factory. Conducts inspections throughout production - not just at the end.

Project Engineer

Order coordination

Coordinates production status and delivery commitments across all active orders. Your point of contact for schedule and status updates.

Process Engineer

Process optimisation

Responsible for optimizing manufacturing processes and resolving production issues before they affect your parts.

Quality you can verify

Every shipment comes with full documentation. Send us your drawings to get started.
