Customer: World-Leading Synthetic Diamond Manufacturer
Scope Summary:
Oxford Engineering was engaged to resolve persistent validation failures in high-tolerance CNC-machined components and pressure-vessel subassemblies designed to operate under extreme thermal and mechanical stress. The complex bill of materials included fragile, high-value components—such as quartz inserts—demanding specialist handling, micron-level precision, and rigorous testing protocols to ensure reliability in harsh environments.
Candidate’s Performance Against Targets:
- Diagnosed initial validation failures, tracing root cause to missing mechanical retention features causing component displacement during leak testing
- Redesigned the assembly to incorporate secure retention systems and formalised test protocols
- Developed and executed 6-bar water immersion tests over 24-hour cycles to validate leak integrity
- Re-engineered assembly sequencing to prevent handling damage to sensitive, high-cost components
- Delivered final assemblies that passed all validation stages with zero non-conformance reports
Support Against Functional Objectives:
Oxford Engineering’s advanced machining and fabrication expertise eliminated critical failure points, enabling consistent operational reliability under demanding conditions. Our process improvements significantly reduced scrappage costs, improved manufacturability through more efficient QA cycles, and enhanced system maintainability via durable retention designs. The project concluded with full customer acceptance and no non-conformances—validating our capability to deliver high-performance assemblies for extreme environments.
