Open hot runner systems
Open hot runner systems: individually configured and application-optimised
We offer hot runner systems in the basic open hot runner and closed valve gate types. The nozzle tip in an open system remains open all the time. With the valve gate systems, the nozzle can be closed off with a needle after each injection process.
Open systems are the standard solution for various applications, and we configure them individually and optimise them for applications as per the customer's wishes. Hot runner nozzles with lateral injection and mini-hot runner systems are only offered as open systems.
As the expenditure for the additional control of the needle drive is eliminated with open systems, they are generally more cost effective than the closed version.
