The aerospace &amp; defense market is a core long-term growth engine for MISTRAS, as the company focuses on expanding capacity and throughput to service widespread industry production backlogs. MISTRAS’ Los Angeles aerospace &amp; defense lab has added new equipment and services designed to help customers manage complex aerospace manufacturing workflows within a single facility. New capabilities include welding, grinding, and rework services, along with two CNC machines and vertical turning centers capable of running parts up to 3 tons. The facility has also added automated ultrasonic testing systems for plate and bar inspection, and coordinate measuring machine dimensional inspection to support precise validation of critical components. These additions build on the lab’s established position as a specialized resource for large-format and high-specification aerospace components. Existing capabilities include radiographic testing, ultrasonic testing (automated, plate UT, composites), magnetic particle testing, penetrant testing, and chemical processing, including etch, passivation, alkaline clean, masking, and related processes. Supporting forgings, castings and weldments, composites, wrought materials including plate, bar, and billets, and machined products, the Los Angeles lab maintains NADCAP accreditation for NDT and chemical processing, extensive Prime certifications, and ITAR compliance. The lab is also expected to achieve NADCAP accreditation in welding. These investments follow recently-announced upgrades to MISTRAS’ Houston, TX lab, continuing MISTRAS’ ongoing strategic plan to enhance the value it provides for aerospace &amp; defense manufacturers, with upgrades to additional facilities planned in the future. “Our customers are looking for trusted lab partners that can help simplify complex production and inspection requirements,” said Cliff Schaffer, Senior Vice President of In-Lab Services at MISTRAS. “These additions bolster the Los Angeles lab’s ability to support customers through more stages of the aerospace manufacturing workflow for mission-critical components.” “Growth in the aerospace &amp; defense market is a core strategic pillar for MISTRAS,” said Natalia Shuman, President and CEO of MISTRAS Group. “We know that our customers in these industries value quality, speed, and capacity.
