Stretch blow moulding
Stretch blow moulding is the definitive method when it comes to producing PET containers. We have been leading in valve technology for stretch blow moulding machines since their emergence.
With our Seitz stretch blow valve solutions, we offer a best-in-class performance which features:
- Minimum dead space
- Quick and repetition accurate valve switching times
- Maintenance-friendliness

Joint development
Regardless of the bottle’s size, the number of produced bottles, and the machine’s specifications, we will work with you to develop the perfect solution. Not only can you count on our expertise, but also fall back on our wide selection of standard products – or otherwise work with our engineers to develop a customised solution, specifically tailored towards your needs.
Valve solutions for existing machines
Whether your machines are new, or have been in use for a while, our products will optimise their performance. Our high-resolution measuring technique allows us to analyse your machine’s blowing process and to show potential points for optimisation. Modern simulation tools re-create the entire stretch blowing process in our laboratory, realistically testing your machine’s expected useful life.
