Injection Nozzle
Injection nozzles provide clean, controlled material transfer between the barrel and the mould. Available in standard, reverse and cone types with free-flow channels, they withstand abrasive and corrosive materials and can be customized to match your sprue and machine, with optional shutoff, filter or mixing function.

Frequently Asked Questions
The nozzle provides the final melt flow path between the injection unit and mold. Its opening, length, connection, and flow design can influence pressure loss and melt delivery.
The nozzle should match the machine's barrel head, mold sprue system, material, processing temperature, injection pressure, and required flow rate.
An open nozzle allows continuous melt passage, while a shutoff nozzle uses a mechanical mechanism to control or stop melt flow and can help reduce drooling.
Yes. ROOTIER supplies standard and customized injection nozzles based on machine dimensions, connection specifications, material requirements, and customer drawings.
