Inspection and Alignment

API offers top quality inspection and alignment services. Our first article inspections allow the customers to have a firsthand look at parts being fabricated from CAD models or drawings. Whether it is inter-company manufactured parts or materials from an outsourced vendor, the 3D measurement data from our scanners and PCMMs offers a comprehensive definition of the physical object being measured. The data can be used for inspection, comparison and reporting. We can deliver 3D color maps, first article inspection reports or 3D models for computer simulation and analysis programs.
