Sustainability with hot runner system

The presentation of a multi-cavity system for the simultaneous, productive manufacture of 72 closures underlines Oerlikon HRSflow's expertise and know-how in the field of caps & closures. Equipped with the new Vf nozzle series, this system enables Short cycle times of 2.2 s to 3.5 s with simultaneously optimised process reliability through precise control and optimum balancing of the filling process.

This technical solution is for Closures for bottles with carbonated and non-carbonated beverages and for liquid and powdered concentrates equally suitable. It makes it possible to meet the requirements of the new European Single-Use Plastics Directive, which stipulates the use of tethered closures for all beverage containers with a capacity of up to three litres.

Specially developed for HDPE caps, the Vf nozzles of the new multi-cavity line from Oerlikon HRSflow are suitable for part weights from 0.5 g to 8 g. They stand for reliably consistent product quality, fast colour changes and system restarts. A special nozzle tip enables Control in the gate area and improves the cycle time. The separate interchangeability of the nozzle tip makes maintenance particularly quick and cost-effective. Rheologically optimised hot runner geometries ensure Increased reactivity and therefore effectiveness of the system. Special inserts minimise the time required for colour changes while keeping the reject rate low, which contributes to the sustainability of production even with particularly critical colours.
