Embedded Metrology Inspection for High-Performance Components

With a full suite of industry-leading inspection technologies, we deliver precision and repeatability at every stage, perfect for sectors where accuracy and reliability can’t be compromised.
Our advanced metrology capabilities include:


  • 8x Coordinate Measuring Machines (CMMs) for external dimensional verification, including the Global S Chrome CMM with X1H analogue scanning head for ultra-precise surface measurement and intricate geometries.

  • 7x CMMs running PC-DMIS and 1x with Quindos software, ideal for critical dimension metrology, including complex features like guides, seats, and bores.

  • 4x 3D laser scanners, used both in our metrology labs and on the shop floor for real-time inline inspection and process feedback.

  • 3x Yxlon CT scanners, combined with VG Elements software, allow for in-depth porosity evaluation, wall thickness analysis, and defect detection.

  • Endoscopic inspection in our PDI (Pre-Delivery Inspection) areas for detailed internal validation, ensuring casting integrity before final assembly.

By embedding these systems across both prototyping and production, we reduce lead times and enable consistent, high-accuracy validation at every stage.

CT Scanning for Non-Destructive Testing and Internal Validation

Our Yxlon CT scanners, paired with powerful VG Elements software, provide non-contact metrology solutions for high-integrity component analysis and:

  • Porosity detection and mapping

  • Wall thickness analysis

  • Early-stage defect identification before machining

These non-destructive testing capabilities ensure each component meets stringent quality standards before any material is removed, minimising waste and protecting structural integrity.
