Direct Part Marking Custom Ship Drive Shafts with C&C Metals

Posted by Matt Martin

C&C Metals, located in West Boylston, MA, had a problem. How would they direct part mark the end of a very expensive custom ship drive shaft and get it just right every time? The first thing they did was call the team at Durable Technologies.


Greg Mancini, QA/QC Manager, explains, "We needed a reliable method of marking the end of a 14 foot long, K-Monel shaft that is also very expensive. We could not afford to make any mistakes with the marking since the material is very hard and very precisely machined."

The marking needed to meet a government specification calling for the lettering to be permanently marked and uniformly applied with a consistent depth using a rounded, low-stress steel hand stamp.

After a telephone consultation and follow-up visit with Chris Podles from Durable, together they came up with the idea of a fixture that would screw into the existing threaded hole on the end of the drive shaft. This fixture positions each custom steel hand stamp exactly in the right place every time. Mr. Mancini marked the fixture slots with the letter and symbol so they would not make any mistakes.

"Using a three-pound sledgehammer and the Durable Technologies steel hand stamps, we were able to make a very clean and crisp mark every time," says Mr. Mancini.

Mr. Mancini continues, "Durable and Chris really came through for us. They understand materials, applications, and how to create a custom solution for low-volume, high-value parts like ours. They really responded quickly and helped us develop a unique solution that really did the job."
