Complete solution for radome design and manufacturing needs
4a manufactruring is your one-stop partner for radome design and manufacturing. We manage the full cycle—from idea to validated product—so each radome meets your requirements and industry standards.
Initial Concept Development
Requirement analysis: operating conditions, frequency ranges, dimensions, mounting interfaces, and maintenance needs. Stakeholder workshops align priorities and constraints.
Conceptual design: early models shared for feedback; risk and cost implications documented; alternative concepts compared.
Feasibility: materials, processes, and cost studies confirm viability; preliminary timelines and test plans drafted.
Detailed Engineering
CAD: detailed 3D models with dimensions and material specifications. Change control ensures traceability.
Radome Transmission Loss Simulation Tool
Demonstrating the benefits of our approach in a clear and visual way.
Electromagnetic simulation: proprietary tool minimizes insertion loss and reflections; sensitivity analyses run for thickness and εr variations.
Finite Element Analysis (FEA): verifies structural behavior under loads; modal analysis for vibration; buckling checks for wind pressure scenarios.
Material Selection
Material database: dielectric properties, mechanical data, resistance metrics, process compatibility, supplier lead times, and cost tiers.
Material testing: verification of εr, tanδ, tensile strength, flexural modulus, and environmental resistance. Certificates archived with project files.
Optimization: stack-up tuned for performance, cost, and manufacturability; decision logs record trade-offs and approvals.
Precision Production
Prepreg layup: controlled fiber orientation and resin content; cure cycles documented for quality records.
Vacuum bagging & autoclave cure: consolidation and cure parameters logged
Injection molding / Thermoforming: process windows defined; wall thickness maps reviewed; post-trim inspection.
CNC machining: toolpaths validated; fixturing ensures repeatability; dimensional reports stored.
Surface treatment: coating thickness, adhesion (cross-cut), and environmental resistance verified; RF cleanliness considered.
Rigorous Testing and Quality Assurance
Environmental testing: temperature, humidity, salt spray, UV, flammability per standard; reports include methods, durations, and acceptance criteria.
Mechanical testing: impact, vibration, wind; fixtures and energy levels documented; pass/fail criteria defined.
Electromagnetic testing: insertion loss, reflection coefficients, and transmission efficiency; results plotted and stored with traceable IDs.
OQC: outgoing quality control with visual, dimensional, and performance checks; shipment includes certificates and maintenance notes.
Wrap-up
As a one-stop partner, CIMERA® covers concept, engineering, materials, fabrication, and testing. The result is a high-quality radome, delivered with confidence and ready for your environment.
