Precision-Engineered for Defense Applications
At Mainstream, we specialize in delivering rugged, high-performance components for today’s most demanding tactical defense systems. Leveraging over 35 years of manufacturing excellence, our team combines advanced technologies with a sharp eye for quality—ensuring every part meets the rigorous standards of the defense sector.
Why Mainstream Is the Trusted Defense Supplier
Certified Compliance for Defense Contracts: We hold AS9100D and ISO 9001:2015 certifications, demonstrating our unwavering commitment to quality management. As an ITAR-registered and DDTC-compliant provider, Mainstream adheres to the strictest export control and confidentiality protocols.
Unmatched Material Versatility: Our 5-axis abrasive waterjet systems and CNC machines expertly process a wide range of defense-relevant materials—from exotic metals like titanium, nickel, and cobalt to armor-grade steels, composites, glass, and plastics.
Cold Cutting Advantage: By using abrasive waterjet cutting, we avoid heat-affected zones, stress, and distortion—crucial for maintaining the mechanical integrity of critical defense components like missile housings, sensor housings, and structural bases.
Tight Tolerances for High-Stakes Applications: Capable of achieving tolerances as fine as ±0.001″, and handling parts up to 24 “ thick within a 240”×120” envelope, our precision enables production of intricate components, such as pressure vessels and complex geometries.
Integrated Manufacturing Expertise
Abrasive Waterjet Cutting
- Ideal for cold cutting specialty armor plates, composite assemblies, and intricate defense applications without thermal distortion.
- We complement waterjet cuts with features like bevels and weld prep to streamline downstream fabrication.
CNC Machining & Swiss Turning
- Post-waterjet, parts undergo precision CNC milling or Swiss-turning to achieve final form with highest accuracy—reducing cycle time and cost.
- Our CNC Swiss lathes support small, complex, high-volume parts from tough defense-grade metals.
Excellence You Can Rely On
- Engineering Depth & Collaboration: From prototyping to full-scale production runs, we partner with your engineering team to refine designs, recommend optimal processes, and help you scale efficiently.
