26 smart_molding international 2/2023 molds and tooling New AXIOM TG single-stage pet hot runner system Modernize your production of single-stage pet bottles to enhance quality and increase productivity with Mold-Masters® new AXIOM TG (Thermal Gate) hot runner system. F or those looking to modern- ize their single stage PET bottle pro- duction. Mold-Masters® has created the AXIOM TG (Thermal Gate) hot run- ner system, which is designed to meet the needs of single-stage PET molders. This hot runner system brings the lat- est processing technology to enhance molded part quality, increase produc- tivity and lower cost per part. AXIOM TG is an economical direct replacement for many existing outdated hot runner systems and is compatible with all lead- ing ISBM machines and molds. Features include: • Incorporation of Mold-Masters proven iFLOW manifold technology • A new optimized, purpose-built nozzle design • Industry-standard gate-seal design Benefits include: • Enhanced bottle quality and reduced scrap rate • Homogeneous melt delivery and rapid color change • Increased uptime and reduced maintenance costs • Retrofittable to existing molds Proven iFLOW Manifold Technology The processing advantages of Mold- Masters iFLOW manifolds have been proven in thousands of applications. iFLOW manifolds are manufactured from two separate pieces of steel with the runner channels carefully milled from each half of the manifold. This allows Mold-Masters to incorporate melt-flow geometries, flow-path options and runner shapes that optimize processing performance beyond the limitations of traditional gun-drilled manifolds. Homogenous Melt Delivery Provides Bottle-to-Bottle Consistency The greatest obstacle preventing bottle-to-bottle consistency is non-uniform melt delivery. Most si ngle- stage hot runners rely on outdated techno l ogy t ha t caus e differences in residence time, shear history and melt temperature, resulting in non-uniform melt delivery. Non-uniform melt delivery through outdated manifolds produce preforms with inconsistent temperature profiles that stretch- blow into bottles with greater wall- thickness variation, such as side-to- side and top-to-bottom variability. The one-stage ISBM process requires the delivery of near perfect melt homogeneity to all cavities. iFLOWManifold Technology achieves greater bottle-to-bottle consistency through optimized melt delivery technology: • Best in-class melt management provides critical processing capabilities for consistent high-quality part production • Industry-leading mold-fill balance from improved shear management • Smooth transitions minimize hang- up spots and dead spots, which allows for rapid color-change performance • Optimized runner diameters address pressure loss, residence time and shear rate • Enhanced temperature uniformity New AXIOM TG nozzles The new AXIOM TG nozzle offers an excellent thermal profile to Mold-Masters® breathes new life into the single-stage PET market by introducing a new optimized hot runner design integrated with proven technology. – Leo Devellian, Single-Stage PET Product Manager Mold-Masters AXIOM TG (Thermal Gated) Single Stage PET Hot Runner System
