Quality control you can actually see.

Our Keyence IM-X system allows us to scan and inspect 15 engine valves simultaneously, measuring critical dimensions across every part and generating a detailed inspection report for each valve.

From overall length and stem diameter to groove location, margin, and other critical dimensions, we’re able to verify production parts quickly and accurately against our specifications.

15 valves. Multiple dimensions. One scan.

Another layer of QC helping us make sure the parts leaving US Seal meet the standards we expect.
