Products & Solutions
MasonOS
Isembard's proprietary operating system for precision manufacturing. It unifies quoting, production scheduling, supply chain tracking, quality management and delivery coordination across the factory network. Using machine learning, it generates instant quotes from component geometry and materials, adjusts machine assignments in real time and runs AS9100D-compliant quality workflows. It also supports robotics integration on modern CNC equipment.
Precision Manufacturing Services
Isembard's factories produce complex machined components and assemblies for aerospace, defence, satellite and nuclear customers. Current capabilities include 5-axis milling and turning, assembly and injection moulding, with fabrication, forging, casting, additive manufacturing and wire harness production planned. Components are manufactured to tight tolerances for critical applications and all production runs through MasonOS for scheduling and quality assurance.
Franchise Programme
Isembard's franchise model allows independent machine shops to integrate MasonOS and join the Isembard factory network. Franchisee factories gain access to the software platform, Isembard's certifications and its customer pipeline. The model lets Isembard scale manufacturing capacity quickly without building every facility itself, targeting independent manufacturers across the UK, Europe and the US.
