Stonehill Engineering


Here at Stonehill Engineering we have a commitment to investing in new machinery giving us a large and varied manufacturing ability.

This allows us to produce quality components, jigs and fixtures from customer drawings and 3D models with our in house 3D CAD/CAM machining facility.
  All the CNC machines are networked allowing easy transfer and storage of machine programs, allowing manipulation from machine to machine enabling fast production and lower lead times.
  The very experienced workforce continuously check all components during production and a final inspection process can be carried out if required by our accredited company inspectors.

Tool Making Services

At Stonehill Engineering we offer a complete part production process with input into part design and manufacture. We can turn your concept into a 3D model/part for production. Once this model is accepted it can progress through different production routes, all of which Stonehill Engineering can provide.

Toolmaking Stages

  • Design Service: We can provide a complete design service or just assistance in the design process for both the tooling and/or your component working to your specifications.
  • In-House Prototyping: We offer an in-house prototype machining service, manufacturing the component from the 3D model on our modern CNC machines.
  • Prototype Moulds: This can then progress to prototype moulds (RPAT - Rapid Prototype Aluminium Tools) being manufactured and then moulded all in house here at Stonehill Engineering, supplying mouldings from 10 to 5,000 off.

Supplying this service all under one roof gives you shorter lead times and reduced costs during the manufacturing process.
