By balancing an advanced in-house infrastructure with a qualified external supply chain, we offer robust "make-or-buy" flexibility. This redundancy eliminates single points of failure, optimizes material flow, and accelerates rapid prototyping while driving down total program costs. Our production footprint is optimized for high-reliability execution, with 25% of our manufacturing floor dedicated to fabrication and 50% to precision assembly. #### Precision Machine Shop We leverage a comprehensive suite of machining tools, from manual equipment to multi-axis CNC milling and turning centers, to achieve ultra-tight tolerances and flawless repeatability. Integrated with industry-standard CAD/CAM software like **Pro/ENGINEER** and **SURFCAM**, our skilled machinists process highly sophisticated geometries and contoured apertures with exceptional quality. #### Advanced Finishing & Chemical Coating To maintain strict quality control and rapid turnaround times, Randtron houses comprehensive painting, coating, and chemical conversion lines. All in-house finishing processes are fully compliant with **MIL-DTL-5541** (formerly MIL-C-5541), ensuring robust corrosion protection and electrical conductivity boundaries are met without third-party transit delays. #### Specialized Composites Fabrication  Our dedicated composites department specializes in wet lay-up processes using advanced engineering materials including **fiberglass, Kevlar, and quartz** across diverse resin systems. Our technicians routinely handle complex tooling and production runs, including applying specialized radar cross-section (RCS) reduction treatments to construct Low Observable (LO) test bodies for our in-house Compact Range.  ### Electro-Mechanical Assembly All critical antenna assembly operations are performed in-house within a highly controlled environment. Production consistency is driven by rigorous tooling, custom assembly fixtures, and detailed process instruction sheets. **>  Workforce Excellence:** All technicians are certified to **J-STD-001** soldering and strict ESD-safe practices. **>  Continuous Improvement:** Active Continuous Process Improvement (CPI) programs ensure lean manufacturing efficiency and defect reduction. #### Manufacturing Engineering (DFM) Our Manufacturing Engineering team bridges the gap between design and physical reality, collaborating early in the product lifecycle with Microwave and Mechanical Engineering. By embedding **Design for Manufacturability (DFM)** principles from the proposal phase through production, we optimize operational efficiencies, conduct rigorous make/buy economic evaluations, and ensure accurate cost estimating. #### Rigorous Production Control & Scheduling To ensure on-time delivery to primary mission timelines, we utilize a computerized, job-specific **MRP system** driven by the Master Production Schedule. #### Quality Assurance (AS9100 / ISO 9001) Our quality management system is fully **ISO 9001 and AS9100 certified**, earning supplier recognition and trust from prime defense contractors including **Northrop Grumman, Boeing, and Lockheed Martin**. Equipped with advanced metrology instruments and precision inspection fixtures, our QA team ensures full compliance for complex aerospace and defense components. #### Accelerate Your Manufacturing Timeline From rapid prototyping to full-rate production, partner with an agile, certified manufacturer. [Contact the Randtron production team today](https://www.fisica.com/contact-us?hsLang=en) to discuss your program's manufacturing and quality requirements.  #### Mission-Critical Field & Depot Antenna Service: Sustaining the Warfighter Extending platform service life demands a highly responsive, well-managed sustainment and modernization framework. Fisica's Randtron Antenna Systems delivers certified depot-level overhauls and global field services that keep mission-critical apertures fully functional, physically ruggedized, and operationally verified. Operating from **ISO 9001 / AS9100-certified** facilities and recognized as a **USAF-approved depot**, we bridge the gap between long-term fleet sustainment and uncompromized theater readiness. ![Lower Hero Banner](https://www.fisica.com/hs-fs/hubfs/Lower%20Hero%20Banner.png?width=2880&height=1048&name=Lower%20Hero%20Banner.png) ###### Contact us # Let’s Start the Conversation Whether you’re looking for detailed product information, a custom engineering solution, or partnership opportunities - our experts are here to help.
