What Cambridge Vacuum Engineering does
Cambridge Vacuum Engineering (CVE), operating legally as Aquasium Technology Limited, is a UK-based specialist manufacturer founded in 1957 and headquartered in Waterbeach, Cambridge. The company designs, builds, and services electron beam welding (EBW) and laser beam welding (LBW) systems, with a built-to-order manufacturing model executed at its Cambridge headquarters. Its product portfolio spans nine core machine families, including proprietary platforms such as Ebflow (a local vacuum EBW system enabling on-site heavy engineering welding at 20-30x the speed of arc welding), Evflow (a purpose-built EV powertrain welding platform), Ebflow Light (local vacuum laser welding up to 60mm thickness), and laser-in-vacuum systems achieving 2-3x the weld depth of atmospheric laser welding. Underlying technology combines high-velocity electron beam physics, vacuum engineering, CNC motion control, and integration with TRUMPF TruDisk laser sources.
The company serves four primary enterprise verticals: automotive and electric vehicles (Ford for EV motor stator hairpin welding), aerospace (aero engine and high-strength alloy components), nuclear (Sheffield Forgemasters for SMR pressure vessels, Kairos Power for pilot reactor vessels), and renewable energy (Dogger Bank offshore wind monopiles), with secondary exposure to electronics/sensors and defense. CVE operates a direct enterprise sales motion through its three offices (UK HQ, Agawam Massachusetts, Beijing China) supplemented by regional partners (e.g., Technika Spawalnicza in Poland) and generates revenue through custom hardware sales and recurring after-sales service, spare parts, preventive maintenance contracts, and training.
The business model is custom-built-to-order with quote-based pricing and multi-year contract cadences, supported by over 60 years of accumulated process expertise, 25 long-serving employees representing 600+ cumulative years of service, and active public-sector R&D co-funding (notably £430K Innovate UK for the Ford EB-eDrive project and £8M BEIS funding for the Sheffield Forgemasters nuclear consortium). CVE has earned multiple Great Place To Work certifications and UK Best Workplaces in Manufacturing recognition, indicating organizational stability alongside its technical specialization.

Products and services
- Ebflow Proprietary local vacuum electron beam (LVEB) welding system for heavy engineering applications. Enables high-integrity welding of large, complex structures without a traditional vacuum chamber by creating a localized vacuum around the weld zone, with welding speeds 20–30 times faster than conventional arc welding.
- Evflow Electron beam welding machine designed specifically for electric vehicle powertrain components, including batteries, inverters, and motors. Built for high-integrity welding of EV-specific parts.
- 60kV EBW Models 60kV electron beam welding machines used to manufacture small components including medical equipment, bellows, and transducers. Low heat input minimizes risk of damage to sensitive electronic components.
- 150kV EBW Models 150kV electron beam welding machines used in aero engine, aerospace, and power generation applications for high-strength and heat-resistant alloys.
- Turbocharger EBW Models Electron beam welding machines specifically designed for welding turbocharger parts used in modern diesel and gasoline engines for improved fuel efficiency and performance.
- Batch and Strip EBW Models Continuous strip and batch electron beam welding machines for large production batches. Suitable for joining two or three dissimilar metals and ideal for EV battery production, reducing labor and material costs by welding continuous strips rather than individual components.
- Ebflow Light Local vacuum laser beam welding machine combining laser welding benefits with CVE's proprietary local vacuum system. Supports in-situ welding of large fabrications up to 60mm thickness in a single pass, with welding speeds up to 30 times faster than arc welding.
- Conventional Laser Welding Models Laser beam welding machines for conventional laser welding at atmospheric pressure using shielding gas. No X-rays are emitted, eliminating the need for expensive vacuum chambers and increasing productivity. Integrates TRUMPF TruDisk laser technology.
- Laser in Vacuum Models Laser in vacuum welding machines that achieve two to three times the depth of weld compared to atmospheric laser welding, with reduced oxidation and exceptionally high weld quality. Features 5-axis CNC motion system for complex geometries and large components, plus wire-feed system for additive manufacturing and cladding.
- Customer Support and After-Sales Services CVE's customer support team provides service and after-sales support including spare parts, preventive maintenance contracts, machine troubleshooting, repairs, training, and development for installed welding systems.
