The PWDS® (Partial Wall thickness Distribution System) allows the dynamic influence on the radial die gap along the parison length.

So, every cross section of the final article can be influenced to the best possible wall thickness distribution. This saves a significant percentage of the necessary raw material by keeping or increasing the test results at the same time. And less material in a much better distribution leads to a high saving in cycle time. Due to the faster cooling times a higher machine output will be achieved.
