Oerlikon HRSflow, San Polo di Piave/Italy, releases advanced hot runner solutions tailored to small shot weights and the new Xp nozzle series for use in thin-wall injection molding. Both support the trend toward greater sustainability by helping to reduce energy consumption in plastic processing.

Reduced Dimensions for Low Shot Weights

The manufacturer now offers complete systems for this market segment, which require tight nozzle pitch solutions. These include nozzles with small dimensions in all designs, from thermal gate to valve gate, as well as the associated manifolds and actuation mechanisms. For multi-cavity applications, a multi-valve plate (MVP) provides perfectly synchronized control of the injection channel across all cavities for high part-to-part weight consistency. Oerlikon HRSflow systems offer optimal color change performance and easy system restart, reducing waste and increasing efficiency and sustainability.

With unique solutions, the new low shot weight system line covers market segments such as medical technology, thin-walled packaging, beverages, and home goods, e.g., caps produced in multi-cavity molds, as well as beauty and personal care and technical applications. The latest version of the system is highly reliable for processing even biopolymers and PCR compounds. A version with a specially coated nozzle tip is available for processing highly corrosive polymers including flame retardant compounds.

For demanding applications, Oerlikon HRSflow uses its in-house additive manufacturing process SLM (Selective Laser Melting) technology to produce cooling circuits for all market segments. Thanks to the joint experience with sister brand Oerlikon Balzers, Oerlikon HRSflow also offers innovative surface protection for all molded part surfaces to increase their corrosion resistance.

For Thin-wall Injection Molding and Stack Molds

The new Xp series of valve gate nozzles from Oerlikon HRSflow is designed to withstand high filling pressures up to 2200 bar and enables fast injection and cycle times in a stable process with high part weight consistency. An innovative, patent-pending solution for stack systems in thin-wall injection molding has been developed. Assembly is extremely simplified and highly efficient thanks to a plug-and-play installation. This hot runner system, which enables the use of smaller injection molding machines, fits a maximum plate thickness of 240 mm. This allows perfectly symmetrical systems with up to 8 plus 8 drops to be supplied, with a minimum pitch between cavities of 65 mm and between nozzle and inlet of 120 mm.
