Mouldmaking and Toolmaking Tool service

Mouldmaking and Toolmaking Tool service, repairs and refurbishment
Within our well equipped Toolroom using the very latest CADCAM software linked to our CNC equipment, we can offer exceptional lead times on both prototype tooling and fully hardened production tools.

We offer an "Inserts only" service where practical, this enables us to produce tooling at a fraction of the time and cost of a full tool. We manufacture Inserts and house them into one of our universal tooling systems.

We have vast experience with unscrewing tooling and have fitted all of the leading manufacturers hottip and manifold systems.

From customers imported CAD files cutter path's can be generated quickly and prototype tooling can be manufactured sometimes in days rather than weeks or months.

We undertake all aspects of sub-contract machining including:

Wire erosion, EDM hole drilling. CNC milling, CNC Turning, Grinding, Surface and Cylindrical
Spark erosion full 4 axis enabling threads and helical forms
