Small formats, tight tolerance on neck finish and fill height, frequent SKU changes.
Pharma runs many small SKUs and changes them often, which puts the weight on tooling rather than on the machine. The mould shop being in the same works as the machine shop is the point here: a new container is a drawing and a lead time.
High-pressure air, chilled water and dry air, plus the mould for your bottle — all built here and sized against each other.
