Welded Reclamation of Forge Dies

Forge Dies #1 (United Kingdom)

 

An axle beam manufacturer in the UK were purchasing up to 80 sets of die blocks a year, each set consisted of 4 blocks, 2 moulds and 2 finishing. A shut height restriction meant that re-sinking could not be used to reclaim the blocks.

 

A programme was devised to reclaim the blocks by the forgeweld layer welding process, and as a result the number of new blocks purchased fell from 80 to 16 per annum, resulting in an annual cost saving of more than £650,000.

 

A breakdown of the cost differences are shown in the table below:
