Passion for hot runner technology

Hot runner systems refer to high-temperature, thermally insulated sprue systems for the effective injection of molten plastics into a mould.

GÜNTHER hot runner systems are individually configured to perfectly suit the customer's wishes. That's why our online product catalogue features a large selection of modular components. Our custom-tailored systems are optimised to process technically high-quality filled or flame protection-formulated thermoplastics. We offer our customers a broad assortment of open hot runner nozzles, valve gate nozzles, single nozzles and system nozzles. Naturally, this can also be combined with a manifold or, as an additional option, a hot half. Our product range also includes cold runner systems, precisely matched regulation and control technology, gate bushings, electrical connections and suitable accessories.
