Thomas Keating - Instruments draws on tool-making skills to design and develop quasi-optical Terahertz systems and subsystems. We have growing activity in High Field Electron Spin Resonance (ESR) spectroscopy and remote sensing instrumentation, including space-borne projects. These newer areas compliment our more established applications like Plasma Fusion diagnostics and material characterisation. Thomas Keating - Toolmaking has a 81 year history of making high precision tooling (press tools, gauges and injection moulds). We aim to give a complete tool-making service, from initial design to tool tryout and maintenance support, combining traditional skills with modern machining techniques and management procedures. We produce precision components in areas such as medicine, aerospace, motorsport, and packaging.
