Nadcap Spray Painted Aluminum Housing with Filled Engrave for Defense Industry

A customer in the Defense and Aerospace Industries needed a high-quality Nadcap certified spray-painting supplier to paint and fill the engraving on a housing that is used on rugged vehicles for the military.

This item is an example of an extremely low-volume part, 15-25 per year, yet it requires stringent quality control due to the customer’s exacting quality requirements and the difficulty of the paint system specified by the drawing. We apply our Nadcap certified spray-painting capabilities to achieve their demanding level of cosmetic appearance.  Finally, our highly trained staff use a precision technique to hand fill the engrave markings with black ink. Throughout the manufacturing process, we subject the housing to stringent quality control measures at every step of the process.
