Our Inspection Services

While other metrology houses and companies offer contract inspection, few can claim to also be the manufacturer of the equipment they use. With industrial Computed Tomography systems, high-precision CMMs, optical and vision instruments, our expertise with ZEISS technology is why you can trust our results. 100% satisfaction guaranteed with quick turnaround on your project. That's the kind of confidence you want in your inspection. 

We have over 50 ZEISS inspectors at six locations, have GDTP and AUKOM certification to guarantee the best methodology, use A2LA-calibrated equipment and PTB-certified software, and have lab monitoring for temperature and humidity. We are ITAR compliant and First Article Inspection (FAI) capable per AS9102 Rev C. Results are also NIST traceable.

ZEISS CT scanning is our specialty, with ten systems available to complete your job faster and less expensively. Analysis capabilities include: FAI reports, porosity and void detection with Pareto analysis, overlaying scan data on CAD to isolate molding issues, assembly analysis to uncover internal mating part issues, wall thickness analysis to spot core shift or thin walls, nondestructive leak path determination, and cavity-to-cavity evaluations to improve mold quality.

Engineering services are also available. We offer onsite support, vacation staffing, lab checkup, and measuring process assessment. We provide mold and plastic assembly validation, FAI, and part reverse engineering. We can help you no matter where you are, yet our local metrology service locations make it very convenient. Visit our dedicated labs in Charlotte, Boston, Detroit, Irvine, Minneapolis, Nashville. Each facility has the full range of equipment.


Airfoil & Blade Components

These components create challenges such as specific industry-mandated inspection protocols, safety concerns, complex design geometries and tight tolerances. Years of work with OEMS and manufacturers allowed us to develop hardware, software and inspection protocols to meet these requirements.

We can report on blade thickness at any point of the nominal profile, torsion/twist angle, blade length parallel to the chord line, stacking point, center of gravity, mean line, form error of the profile, pitch between blades, throat distance between blades and platforms, maximum length and thickness, corner radius and thickness of the leading and trailing edge. For impellers, we offer advanced best fit algorithms. With blisks, we can provide stacking axis, mean line, and true position calculation. For vanes, we offer accurate measurement and analysis of leading and trailing edges.

Gears, Hobs & Rotors

Inspection is challenging due to complex design geometries, five- and six-axis machining processes and tight tolerances. Our engineers have years of experience with these applications, using tested and proven quality processes.

  • Involute Gears—Involute Profile: Internal/external, spur/helical, gear segment, conical, beveloid
  • Involute Gears—Straight Profile: Internal/external, serrated spline, parallel key spline
  • Worm Gears—K-Charts: ZI, ZA, ZN, ZK
  • Gear Hobs: Full and tangential profile
  • Bevel Gears—Straight/Spiral Profile: Ring and pinion, electrodes, dies, hirth couplings
  • Rotors—Male and Female: Profile, lead, pitch, root and tip plots

Medical Devices, Assemblies, Containers, Closures and Forensics

These components can be difficult to measure because of thin plastic walls, tiny and many geometrical details and issues associated with the conventional way of destructively cross sectioning the part or assembly. We wrote the book on nondestructively scanning of these types of parts with our METROTOM CT CMMs and software. We offer:

  • Assembly inspection: nondestructive digital X sectioning
  • 3D leak path and mechanical fit analysis
  • Wall thickness and warp analysis
  • 3D color-mapped dimensional report to CAD
  • Forensics analysis
  • 3D void analysis


Aerospace: Composite fiber orientation analysis, NDT for castings and pistons, reverse engineering and simulation studies for assembles components, electrical component inspection, first article inspection performed under AS9012, large parts measurement of flaps and wings and blades, reverse engineering of pieces or assemblies, free-form scanning, and very small and micro components.

Automotive: Gear services for the detailed and precision measurement of transmissions. Body or interior molded parts measured with our laser-scanning systems. Inspection of surface finish, external dimensions, holes, fuel injectors, microparts, pistons, cylinders, camshafts, engine components and performance racing applications.

Electronics: We use tactile inspection to locate the part followed by vision or white light inspection for the rest. We measure flexible circuits, connectors, BGA sockets/pins/balls, PCB, pins, dies, stencils, lead frames, Jedec carriers or trays.

Forensics: Non-contact inspection with CT and the careful handling and scanning of damaged parts.

Medical Device Manufacturing: We measure assemblies, electrical component, implants, dental implants, stents, tubing, hearing aids, nozzles, needles and pins, dental screws, surgical blades, syringes, valves, microparts, and surgical tools.

Micro Parts: We use tactile probing with small styli and light measuring forces and ultra-precision CMMs to tackle the toughest jobs.

Plastics: We use CT to speed up tool corrections and save money. We offer visual and other solutions for the molding process. Defect analysis, wall thickness analysis and assembly analysis provide the material properties and quality of the first shots. We do process analysis and void analysis. We specialize in measuring small and soft plastic parts, molds, connectors, and implants.

Art: We help with inspection applications for unique and precious, rare items. 

Our Inspection Process

  1. To understand your industry and application challenges, we start with a non-binding consultation (in person, phone, or video conference) to determine requirements and expectations.
  2. We review any part drawing blueprints with the highlighted desired dimensions. If available, we use your CAD model in native or neutral format.
  3. We then determine part fixturing needs, part quantitiies and the project timeframe. Non-disclosure, confidentiality and security issues such as ITAR are considered.
  4. Once we receive your parts and materials, we determine the best technology for your application and then develop a draft inspection plan.
  5. We quote in detail the requirements, expectations, and schedule. Upon project approval, we complete the inspection plan, any necessary fixturing and test the setup.
  6. Once it passes, we begin inspection. Reports are generated in formats such as CALYPSO, Excel, PiWeb, etc. We have a peer-to-peer review of the results and then deliver them to you for review. 
  7. Once a satisfactory solution is provided, we invoice you and return all parts and material. And, we offer a complete back-up of measurement results.
