Open hot nozzle is a heating component used in hot runner molds, usually composed of needle valves, heaters, sensors and other components. Needle valves can control the flow of liquid, heaters can heat liquid, and sensors can detect liquid temperature.

The working principle of the open hot nozzle is to adjust the temperature of the heater through the control system, so as to control the heating temperature of the liquid. As the liquid flows through the hot nozzle, the heater heats the liquid to the desired temperature, and then the needle valve is closed or opened, controlling the flow of the liquid.

Open hot nozzle has the advantages of high efficiency, energy saving, environmental protection, etc., can precisely control the heating temperature and flow of liquid, improve production efficiency and product quality. At the same time, it can reduce the waste of raw materials and reduce the emission of waste gas, which is friendly to the environment.

Needle valve hot nozzle is widely used in injection molding machines, extruders and other plastic processing industry, used to control the heating and flow of plastic raw materials, so as to control the quality and production efficiency of plastic products in the mold.

Open hot nozzle is a hot runner system widely used in injection molds, the model H25, needle valve hot nozzle. This hot runner system has the following characteristics:

Needle valve design: The open hot nozzle adopts needle valve design, which can accurately control the flow and injection of plastic, achieve better filling effect and product quality stability.

High temperature performance: the hot nozzle can withstand high temperature, can work stably for a long time in a high temperature environment, to ensure that the plastic remains molten in the hot runner, improve processing stability and efficiency.

Flexible and changeable: The open hot nozzle can change the flow path and injection amount of plastic by adjusting the Angle and position of the needle valve according to the needs of different products, to achieve rapid mold change and multi-mode production at the same time.

High reliability: The nozzle is made of high-quality materials and processes, with high reliability and durability, to ensure long-term stable production.

Easy maintenance and maintenance: open hot nozzle structure is simple, easy maintenance and maintenance, can reduce the cost of use and maintenance costs.

In short, the open hot nozzle is a high-performance, high-efficiency, high-reliability hot runner system, which can be widely used in the production of various plastic products, improve product quality and consistency, reduce production costs, improve production efficiency and flexibility.
