Tested, not just specified

Engineering know-how
Design and development, CNC machining, 3D scanning, surface treatment and finishing are all part of the foundry's service, so a question about a casting can be answered by people who know how it is made.

Supply you can rely on

Production control
Quality you can trace
Working with our foundry partners, every casting we supply can be traced back to the single sand mould it was made in, the batch of molten metal poured into it, and that metal's exact chemistry at the moment of casting.
That level of control means any deviation can be found at source and put right quickly, and it underpins our ISO 9001 quality management and BSI Kitemark accreditation.

What we stand for
Part of the Thomas Dudley Group
TDUP sits alongside our fellow Thomas Dudley Group businesses, forming a diverse industrial group with a shared foundation in British manufacturing.
Sustainability — Our Journey to Net Zero
The Thomas Dudley Group is committed to decarbonising by 2040, becoming a net-zero business through targeted energy consumption analysis, local monitoring across all our plant and equipment, and collecting emissions data across our whole value chain.
We’ve introduced our own Energy Policy to help establish these commitments, and we’re investing in new technologies and plant equipment designed to reduce our overall emissions and energy consumption as we work towards that 2040 target.
Supplier partnership
Over 10 years with Howrah Ferrous
Every casting we supply can be traced to the individual sand mould it was made in. See how our long-standing partnership makes that possible.
