PressingOur 700 ton press allows us to produce hot or cold flanged plates to most dimensions required in heritage steam today as well as countless other industrial applications. 
700 ton press
We can supply tube plates, back heads,
throat plates, foundation corners and much more. Not just of use to the boiler
trade but anyone requiring superior quality pressings.
The machine was manufactured in 1975 by John Shaw and
Company. Originally installed at the British Rail works in Crewe, the press
then moved to a pipe fitting manufacturer in Warrington in 1995. In November
2000 the press was installed at Pridham's works, moving to Buckfastleigh in September 2010.
The press is used mostly to produce flanged plates for
steam boilers such as back heads, throat plates and tube plates. Also it
enables us to develop large pressings like those for fire box side plates
somewhat like a large press brake.
Although primarily intended for the manufacture of
locomotive parts we are keen to offer the diverse capabilities of this machine
to other industries not only in the south west but throughout the country. We
can produce large diameter dished ends in plate up to 1" (25mm) thick or other
shapes to your requirements. Pressings can be an economical alternative to
fabricated parts in many industrial applications.
The machine has a combined pressing force of 700
tons through three sets of upstroke rams. These rams can be operated
independently to increase the range of capability of the machine.
We provide a full developing service or press only
options to suit your needs.
We work from component drawings and produce one off or
batches of parts to your specifications.
Alternatively we can use your free issue tooling for
one off or longer runs. Please feel free to contact us to discuss any
requirements you may have.
We have a three tonne and a seven tonne forklift on site and can accommodate larger pieces by special arrangement.

Hot pressed chimney base Press Arrangement
The press has a bed of 12' X 8' (3657 mm X 2438 mm)
and a daylight of 5' (1524 mm).
The centre ram (red) can lift independently through the bed for a second press operation or as an ejector with about 205 tons of force. Alternatively it can be clamped to the main bed, taking the full push to over 700 tons. The adjustable vicing rams (green) lift through the table and are designed for clamping the work piece in place during pressing. They can provide 200 tons of upward force between them.
