One place I worked we would marry a mold to a machine.
(always run it in a particular machine)
Sometimes the exact same machine right next to it would have trouble running that mold? - you wouldn't think it would be a process change?

No 2 machines can ever be the same, wear, oil, calibration ete etc.
One of the important factors is all stable process is the machine and if this changes the process changes.
It could be environment, a draught could affect the performance of a border line mould critically.
For you it is important to validate your production process, in the end you pay for the scrap.
