RDI develops high-performance products and complete engineering solutions for systems where pressure, purity, reliability, and mission success cannot be compromised.
RDI engineering supports mission-critical fluid-control applications where precision, reliability, and disciplined validation are essential to spaceflight performance.
RDI combines product design, multidisciplinary engineering analysis, program execution, and validation to develop hardware for demanding aerospace and industrial environments.
About RDI
Engineering heritage since 1997
RDI Engineering was established in 1997 by founder Ardi Rashidi. Across RDI Engineering and RDI Manufacturing, the team has supported product design, engineering analysis, program management, precision fluid-control hardware, thermal-system design, and demanding pressure-measurement applications.

Advanced engineering services
Engineering support from concept through validation
RDI supports individual engineering studies and complete product-development programs, helping customers define requirements, evaluate concepts, resolve technical risks, and deliver solutions ready for implementation.
Establish a clear technical foundation by defining the operating environment, performance objectives, constraints, risks, and practical development path.
Convert technical requirements into viable concepts, component configurations, system architectures, and development strategies suited to the intended application.
Assess performance, pressure behavior, fluid conditions, structural response, materials, interfaces, and potential failure modes before the design is finalized.
Produce the controlled engineering definition needed to manufacture, procure, assemble, inspect, operate, and support the final product or system.
Develop and support evidence-based testing programs that verify performance, confirm design intent, and identify issues before deployment.
Consolidate analysis, design documentation, test results, procurement information, and technical recommendations into a complete, decision-ready engineering solution.
