In modern high-speed beverage bottling and rigid packaging manufacturing, hourly throughput, cycle time consistency, and specific energy consumption dictate overall profitability. To demonstrate the real-world capabilities of Kronce systems, we documented a live production run producing lightweight PCO 1881 water/beverage preforms on a high-density 48-cavity system.

Engineering Advantages of Kronce Systems

  • Rapid Clamping & Dynamic Kinematics: Platen rigidity and servo valve control deliver minimal dry cycle times without vibration or mold impact.
  • Individual Cavity Thermal Uniformity: Advanced balanced hot runner manifolds ensure exact gate-to-gate melt pressure and tight weight deviation (< ±0.1g).
  • Synchronized External Post-Cooling: High-speed take-out robots transfer preforms into multi-station cooling plates, freeing mold cycle time for immediate subsequent injection.
  • 0.20 kWh/kg Specific Energy: Intelligent variable-speed servo hydraulic pumps paired with barrier-flight screw designs maximize plasticizing output while slashing factory utility bills.
