3D scanning is a fast, flexible, and highly accurate way to gather data that can be analyzed to provide feedback on the accuracy of your manufacturing process. IIA has extensive experience in the dimensional inspection of a wide variety of precision components. This expertise, coupled with 24-hour operations, allows for a rapid response to all of your inspection needs. Partner with IIA and gain confidence in your manufactured products and processes.

The Dimensional Inspection Experts

Dimensional inspection (also known as: metrology services, validation, verification, product evaluation, contract inspection, and layout inspection) is performed to compare the actual condition of a manufactured part or component to that defined by engineering drawings and blueprints, metal or film templates (decreasingly), digital files and 3D CAD models (increasingly), or even a master tool or part.

There are many ways to establish product definition or to define design, and even more ways to measure and inspect the actual product manufactured. That’s why IIA has amassed an impressive array of state-of-the-art measuring instruments, equipment and technology.

These technologies, coupled with our team of highly skilled, trained, and experienced professionals, allow us to provide high-quality, yet cost-effective, service that is unmatched in the industry. The end result for you is impartial, unbiased, and comprehensive dimensional measurement data you can depend on.

Our expansive, environmentally controlled laboratories are well equipped to handle virtually any inspection need, large or small, with accuracies and measurement resolutions down to mere nanometers.

We provide timely, easy-to-understand results in a variety of reporting formats, including customer-specific formats. See our Additional Inspection Specialties page for even more dimensional inspection services offered by IIA.
