Introduction from the Chairman, Paul Duncan

Paul Duncan - Chairman

The Bonds group comprises four foundries, primarily steel, which together provide a comprehensive, strategic, product offering in castings.

Our strategy of acquiring traditional, longstanding foundry businesses at value prices and managing them better for the future, together with substantial investments in new foundry equipment, has enabled BondsHold to build a foundry group with an ability to manufacture a wider range of castings than any other foundry group in the UK.

Continuance of this strategy of acquiring engineering assets at value prices is envisaged, but with more emphasis on vertical integration. Structural changes in the international market place for essential engineering products and applications will no doubt continue for a while to create acquisition opportunities at value prices.

In recent years, Bonds Foundry, Bond Precision Castings and Darwins have had a customer base primarily related to steel pump casings and impellers for OEMs in oil/gas pumps.  Due to the fall in the price of oil and the subsequent curtailment of new projects, this market reduced – although the aftermarket has held-up somewhat. This is a temporary aberration as oil/gas developments cannot be postponed indefinitely. 

Castings for warships is also an important market and the group is well placed on new UK power generating marine developments. For the post-Brexit UK economy, Bonds will provide a potentially important domestic strategic capability.

The group’s newest acquisition, Bonds Heavy Castings, has a capability in iron and steel up to 25 tonnes finished weight with machining and specialist heat treatment.  Equipment would have a replacement value of many times the sum paid for it.  With market recovery and redirection away from its traditional, high-chrome iron, wear-parts business into high-specification steels with large oil/gas and power applications, the company and group will be extraordinarily well-placed for the future.
