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

Aircraft Connectors

Scientific Management International is a versatile manufacturer of bespoke moulded cable systems. Many of these cable systems utilise connector arrangements to aid installation and through life maintenance schedules. Our versatility comes from our ability to work with multiple connector manufacturers to suit the application and environment.

These connectors coupled with Scientific Management International’s high performance mouldings ensure products are engineered for a ‘fit & forget’ solution.

Aircraft environments expose aircraft cable systems to a range of dynamic environmental extremes. Traditionally these cable systems utilise off the shelf materials to be a low cost solution. These solutions are not long term and require constant replacement and through life costs. We deliver high quality bespoke moulded cable systems tailored to the environment, to deliver the most cost effective, robust and reliable solution.
