Open Hot Runner Nozzles The different nozzle types, whether as a single nozzle or for multi-tip gating, allow you to realize any number of applications. Based on the modular design, individual parts, such as the heating element, sensor, material tube and nozzle tips, can be replaced. This offers great advantages when performing repairs and maintenance work (time savings, lower repair costs, less downtime). GNTHER standard hot runner nozzles will sell themselves with outstanding thermal separation afforded by the two-component shaft. This willl ensure excellent insulation in the front shaft area and very little heat loss between the hot runner nozzle and the cavity. These nozzles are suitable for processing of heat-sensitive materials, technical plastics, and high temperature polymers. With filled materials, such as glass fibres with heat stabilizers, wear-resistant heat conductor tips provide the best possible protection against mechanical and chemical attack. Standard
