Mechanical Engineering Sector

Functional parts for testing, validation and performance

Mechanical engineers rely on accurate, durable parts for validation, testing and mechanical assembly.

We produce high-quality prototypes and small-batch production parts that help prove concepts, verify function and support final design decisions delivered quickly and consistently from our facility in Royston.

From mechanisms and housings to full test rigs, our parts are built to perform under real conditions.

Key capabilities

  • SLA 3D printing for detailed models and smooth surface finish
  • SLS 3D printing for durable, complex functional components
  • CNC machining for metal and engineering-grade plastics
  • Injection moulding for pilot runs and design validation
  • Vacuum casting for quick replication of rigid or flexible components

Typical applications

  • Gearboxes, linkages and bearing housings
  • Pump bodies, valves and flow components
  • Structural and load-bearing parts
  • Jigs, fixtures and assembly aids
  • Functional test rigs and working prototypes

Supporting engineers across development

We provide dependable quality, clear communication and full ISO 9001 and ISO 14001 assurance helping you move confidently from design through to production.

When your in-house capacity is stretched, we become your extended workshop – fast, flexible and UK-made.
