How we work
A practical path, not a fixed formula.
Each project can enter, revisit or combine stages as the work requires.
Design & analysis
Develop and refine the concept with manufacturing, materials and performance in mind.
Prototype & manufacture
Turn the design into accurate parts, prototypes and assemblies ready for use or review.
Verification & testing
Check finished work against the agreed requirements before release.
What we do
Core services
Five connected capabilities, from early design work through manufacture and assessment.
Design
Concept development, CAD and design-for-manufacture support to turn requirements into workable geometry.
CNC machining
Fast-turnaround CNC machined prototyping in demanding materials including aluminium, PEEK and stainless steel.
Reverse engineering
Recreate accurate digital models from existing parts, drawings or measurements for replacement, improvement or manufacture.
Structural analysis
FEA-led assessment using non-linear, explicit and implicit methods to understand loads, performance and failure behaviour.
Welding & fabrication
High-precision TIG welding for aluminium alloys and stainless steel, with clean joints for critical assemblies.
Technical capability
Built around accurate work
Advanced metrology
In-house 3D laser scanning and Renishaw probing for complex geometries and tight tolerances.
Traditional inspection
Calibrated surface plates, Mitutoyo calipers, micrometers, height gauges, slip blocks and pin gauges.
BS8888 / GD&T
Capability to read, interpret and manufacture to strict BS8888 GD&T technical drawings.
High-pressure systems
Machining structural components and high-stress fixtures rated for environments up to 15,000 PSI.
Selected work
Previous projects
Examples of machined components, workholding and inspection work.
