Heronstone Engineering Ltd T/A Harlech Tools

5 - South West and South Wales


Heronstone Engineering T/A Harlech Tools specialises in the manufacturing of high precision engineered components for almost all branches of industry, continually updating machining capabilities to maintain accuracy, quality, production efficiency and cost effectiveness, and to keep pace with the increasingly more stringent requirements of modern technology.

In line with this policy, the company has invested in the latest CNC precision machines and electronic inspection equipment to ensure that it is able to guarantee that all contracts are delivered on schedule, at the right price, and to the highest standard.


Tool Room

The Tool room facilities include the design development, manufacture refurbishment of press tools. Special purpose jigs and fixture.


Using to its advantage 38years of experience together with modern technology own press shop to ensure that the tools are ready to run in a production environment.

General Machining:

CNC Milling, Turning, and wire erosion also undertaken.

Key Equipment:

Includes wire erosion CNC milling and turning with CAD CAM facilities.

Tooling Discounts:

Bespoke tooling costs can be discounted if production work is also carried out by Harlech Tools.

Press Work and Assemblies

The press shop covers a wide range of products, which include press stampings and assemblies. All tools jigs and fixtures are manufactured and maintained on site in our own well-equipped tool room.

Facilities Include:

Power presses up to 50 tonnes fitted with the latest load monitors to protect customer tooling. We also have a large selection of universal tooling and second operation machines, which are ideal for low volume production batches, where capital investment and special tooling is not required. Can also be used to produce prototypes components for testing prior to the manufacture of special tooling.

Additional processes:

Include spot- welding, mig-welding, guillotining, drilling, tapping, vibratory de-burring etc.


Because we offer a complete range of sub-contract services in house from prototype to final assembly we can give very competitive prices and lead times.


When production is carried out at Harlech Tools, special tooling costs can be heavily discounted.


Precision Turned Parts

Harlech Tools invested heavily in the latest CNC sliding head and turret lathes, to maintain accuracy, quality, reliability and cost effectiveness. Many of the machines have live tooling and sub spindles which means even the most complicated parts can be produced on one machine without the need for secondary operations.

Around The Clock:

All machines are fitted with magazines bar loaders to give fully automated around the clock repetition of high precision turned components in the complete range of ferrous and non ferrous metal and special materials. With the advantage of tool room support, press shop and assembly's facilities, Harlech Tools are able to offer a complete sub contract service
