XMOULD is an innovation from Sipa which allows reduction of friction between molten PET and molding surface of the injection stacks during injection phase, allowing production of thin-wall performs with length on wall thickness ratio above 50 (L/t in the range of 50 to 55 possible), so better/optimized thickness distribution on final packaging (avoid the accumulation of material on zone as under-neck and bottom areas).
XMOULD technology givesdesigners the power to create lightweighted preforms which do not compromise performance of the final container.Besides the possibility to reduce preform thicknesses, this solution also improves cycle times due to friction reduction at filling phase.
Available on new or legacy tooling, only special injection stacks are required to enjoy the XMOULD technology, no changes required neither on the machine nor the hot runner.
