Engineering Services

One preform is not suitable for every bottle. For optimal stretch ratio PET preform geometry needs to be compatible with bottle dimensions. This is specifically relevant in case top bottle quality is the goal, and sometimes preform (re)engineering is needed. We have partners who will be eager to help you with achieving that ambitious result.

Preform Stretch Calculator

By the use of PET prefrom stretchin simulation software we determine potential risks that can occur when stretching the bottle. This way before investing in the injection mould we have a possibility to create a virtual quality profile of the blown bottle according to which we can alter the preform or bottle drawing, if needed.
