Cold Runners

Made with the same passion as hot runner systems, Gúnther also offers cold runner systems for LSR processing. Simple construction, modular nozzle design and excellent thermal separation between nozzle and cavity allow us to offer excellent solutions for cold halves injection.

Cold half full as standard

GÜNTHER offers complete cold halves that can be purchased as standard and efficiently integrated into the corresponding moulds. The nozzle contact surfaces are as small as possible between the hot cavity plate and the cold half to ensure thermal separation. The flux helps to compensate for the heat expansion. The flow volume of the cooling medium provides an ideal temperature profile.

Valve Gate nozzles for cold channels

The GÜNTHER product range has two valve nozzles for cold runner systems. These nozzles can be used individually or in a common housing for narrower cavities with a common inlet and outlet.
