TCDC is ITAR Compliant, and we maintain the ability to produce parts for the defense industry with annual quantities in the thousands to millions per year. Our engineers are experts in redesigning parts into die castings, with return on investment possible within 3-6 months. Our in-house sanding and finishing room helps expedite production to your exact specifications, and our trained cosmetic inspectors are experts at supervising processes such as painting, or plating. In 2010, TCDC received the Program Director's Service Appreciation Award from the American Metalcasting Consortium (AMC), for helping develop supplier relationships with the Defense Logistics Agency (DLA).

Due to the sensitive nature of our contract work and ITAR controls, as well as, confidentiality agreements with our valued customers, we are limited in describing the applications, or displaying individual product application images. However, our customer base includes many of the well known companies in the defense industry.

Applications include die cast aluminum enclosures, heat sinks, portable rugged housings, and hand held devices for the military and defense industry.
