From the scrap yard to the
production plant
Bühler Die Casting offers a customised retrofitting programme in collaboration with its Italian partner, Brescia Presse for
diecasting machines of all sizes and makes. The following contribution describes two neglected Evolution 180D machines
that were completely overhauled and made ready for production in Europe and Asia.
Neither of the neglected Bühler Evolution 180 D
diecasting machines (18000 KN locking force) had
been used for quite some time. The original buyer
miscalculated his market opportunities and had
built up more capacity than could be used.
The two machines were only used as ‘spare parts
warehouses’ and consequently, were in poor
condition when purchased by a globally active
foundry company at reasonable terms and
conditions. The internationally successful foundry
was in urgent need of increasing production
capacities at its factories in Europe and Asia above
and beyond its existing Bühler machinery and
found what it was looking for in the US second-
hand market.

This meticulous planning proved to be the key

that point, the company was able to put together a
