Every gram counts
You're thinking: “What can one gram
more or less possibly matter?” And
our answer is: quite a lot – as this
actual example goes to show:
The job profile:
■■ Weight optimisation for a 0.5-litre
bottle weighing 15 g
■■ Bottle runs on three lines, each
rated at 36,000 containers an hour,
an operating time of 5,000 hours a
year and an OEE von 75 %.

Identifying improvement potentials
Losing weight in the right places
If you're going to slim down, then
do it properly: reducing the weight
of bottles is a ticklish business. Even
the tiniest of alterations can entail
unpleasant consequences for processability. So lightweighting means
quite a lot more than just “tweaking
away” a few grams here and there.
Lightweighting is a complex design
process that focuses on ideal material
distribution for saving weight while
retaining the requisite quality features.

Savings in the high-price segment
Imagine you've lost weight and no
one notices
Rather a nice idea – at least for premium products. After all, they're
expected to be stable and pleasant to
handle. Weight reductions can have
devastating effects here. Unless our
designers have had a hand in them.
They're quite capable of squeezing
another gram or two even out of bottles in the high-price segment. These
savings don’t show up in the bottle
itself – but they most certainly do in
your bottom line.

your production managers alike!

Design that really works
Why settle for a compromise when
you can have everything?
Out-of-the-ordinary and nonetheless fit for purpose? Product design
is a balancing act between creative
flair and technical feasibility. Design
offices pure and simple are often not
up to this sort of challenge. Our own
designers, by contrast, know exactly
what the bottles and other containers
can expect in the production environment, and what kind of stresses they
will have to cope with. Because they
have the entire fund of krones' accumulated expertise to tap into. Which
means they're probably the only creative minds who are backed up by long
decades of relevant experience as a
complete-systems supplier. An advantage you can't help noticing!
