Reduced stack height of PET-series hot runner system
Mold-Masters, a leading developer and supplier of hot runners, controllers, auxiliary injection, and co-injection systems, announces the optimised design of its PET-Series hot runner system. The stack height has been reduced to 260mm on systems with 72 cavities or less using standard components.
Traditionally, more compact stack heights required a 2-platen design. The PET-Series, however, maintains its 3-platen design to preserve all the advantages associated with that configuration. The 3-platen design, specifically for PET applications, helps improve geometric thermal balancing and reduce plate bowing to enhance preform quality.
By offering a more compact stack height, moulders can run the system on a wider range of machines, including older generations, that have stack height limitations of 260mm. The minimum nozzle pitch of the PET-Series is not affected and remains the same as regular 3-plate designs.
Mold-Masters PET-Series is a hot runner system optimised for high-performance production of 2-stage PET preforms. The PET-Series is claimed to enhance preform quality while increasing productivity. It is compatible with any major brand of pet-preform mould and available in a wide range of industry standard configurations. Custom configurations are also available upon request.
