PET Preform Hot Runner System Reduces Stack Height
Mold-Masters has cut the stack height of its PET-Series hot runner system from 300 mm to 260 mm, while maintaining a 3-plate design and the advantages therein.
Mold-Masters has optimized the design of its PET-Series hot runner system to reduce its stack height to 260 mm on systems with 72 cavities or less, while using standard components. The prior stack height for a comparable system was 300 mm, according to a company spokesperson. Mold-Masters notes that in most cases more compact stack heights require a two-plate design, but the new PET-Series maintains a three-plate design, which preserves the advantages associated with that configuration. Specifically for PET applications, the benefits of a three-plate design include improved geometric and thermal balancing and reduced plate bowing, which enhance preform quality.
The compact stack height also enables molders to run the system on a wider range of machines, including older generation presses that have stack height limitations. The minimum nozzle pitch of the PET-Series remains the same as regular three-plate designs.
Designed for production of two-stage PET preforms, the Mold-Masters PET-Series is compatible with any major brand of PET preform molds and available in a wide range of industry standard configurations, with custom configurations available upon request.
