Frequently Asked Questions
An LSR shutoff nozzle is designed for liquid silicone rubber injection molding applications where controlled material flow and reliable shutoff are important.
The LSR nozzle features low‑viscosity and high‑flow characteristics. It must be equipped with seal and cooling structures to prevent drooling and premature vulcanization.
Selection of LSR nozzles shall be based on specific machine size, shot volume, injection rate and installation dimensions.
ROOTIER has standard model for LSR shutoff nozzles, the connection size can be customized base on your machine connection dimensions and application requirements.
