A Seattle-area materials science company, M9 Defense , raised $1.4 million in a series A round, a new SEC filing revealed. According to the company's website: its core product, Boroclave presses, use hydroforming technology to mass-produce ballistic and non-ballistic composites. The company claims the composites it uses have the highest strength to weight ratios available in today's market, and can be formed into products at speeds comparable to that of sheet metal processing.
