unassailable ‘fit & forget’ pressure moulded cable systems for hostile environments

Aerospace

Scientific Management International is a versatile manufacturer of bespoke moulded wiring harnesses and cable assemblies. Working with a variety of cable & connector manufacturers to suit the application and environment, these aircraft cable connectors coupled with our high performance mouldings ensure products are engineered for a ‘fit & forget’ solution. Utilising technologies with a 25 year pedigree in subsea applications, Scientific Management International engineer high quality bespoke assemblies which deliver high performance and long term reliability and reduce through life cost.

Aircraft environments expose wiring harnesses to a range of dynamic extremes. Thermal expansion and contraction and pressure cycling during altitude changes can produce problems over time for power and data systems, as condensation pervades connections through traditional sealing technologies. High pressure, high temperature thermoplastic moulding produces chemical bonds between cable and connector shell materials achieving durable sealing for extend life service.

Pressure gland technology applied for 25 years in submarine applications is tailored for safe through fuel tank cable routing; and reliable electrical harness impervious to moisture ingression provide opportunities to migrate from hydraulic to electrical control systems.

Our expertise is borne from decades of experience, and these characteristics are just an indication of what is possible. Our strength is in working with the client on the specific challenges of their applications and designing bespoke cable systems to deliver performance and long term reliability.
