Rotating IS Machine 🇬🇧

I've seen these IS machines with multiple blow moulds mounted on a carousel, which are made by the Chinese company Chuda, now in quite a few videos. And I always asked myself: what's the benefit of such a complicated and unconventional design?!

During my recent trip to China, my colleague Tony had the explanation: the multiple-mould arrangement leads to a longer re-heat time, resulting in much higher surface quality 🤓 This then also explains the take-out and transfer arrangement as well as the deltabot lehr loader: the outside of the bottle is never touched and thus stays pristine.

According to Tony, during the last few years these Chuda machines have become quite well-spread among high-quality container manufacturers all across China. We visited three different spirit bottle manufacturers – all of them had at least one line running. The machine takes up more space and is slower than a standard IS machine – but the benefits seem to be striking. On the web one can find photos of machines with up to ten stations … double-gob is also available!

And as an interested bystander I now wonder: what do the big players like Emhart, Heye or Bottero and BDF think about all of that?
