The silicone needle-valve cold nozzle is a precision cold-runner nozzle specifically designed for LSR (Liquid Silicone Rubber). It integrates functions of needle-valve glue-sealing, forced cooling, and heat-insulation to prevent vulcanization. This nozzle can eliminate drooling and dripping, create aesthetically pleasing and mark-free gates, precisely control material supply for balanced multi-cavity filling, save materials, and improve efficiency. It features a modular design for easy maintenance, meets high-cleanliness requirements suitable for medical and food-grade applications, and is the core preferred solution for high-precision, fully-automated LSR mass-production molds.
