What is industrial CT scanning?
Industrial CT (computed tomography) scanning uses X-rays to create a complete 3D model of a part, revealing both external and internal geometry without destroying the sample. It enables inspection of internal features, voids, porosity, wall thickness, and assembly fit that cannot be measured with conventional tools.
What dimensional inspection capabilities does DDL offer?
DDL offers industrial CT scanning, optical measurement, vision systems, and calibrated hand gauge measurement. We support GD&T evaluation, first article inspection, incoming quality inspection, and failure analysis for components of all sizes.
What tolerances can you measure?
DDL's measurement capabilities range from sub-micron resolution with CT scanning. Specific measurement uncertainty depends on the method, feature size, and environmental conditions. Contact us with your drawing and tolerances for a capability assessment.
What metrology standards do you follow?
DDL follows ISO 17025 for laboratory accreditation, GD&T evaluation, first article inspection for CT measurement. All instruments are calibrated to NIST-traceable standards with documented measurement uncertainty.
Do you offer dimensional inspection services near me?
DDL operates multiple laboratories across the United States. We also accept shipped samples with fast turnaround on inspection results. Contact us to discuss the most convenient option for your location and project requirements.
