Needle valve series

Needle valve hot runner system is a common type of hot runner technology that controls the flow and stop of plastic materials through needle valves to achieve more accurate injection molding processes. The following is the general display and main components of the needle valve hot runner system:

1. Needle valve controller: A needle valve controller is usually an electronic device used to control the action and timing of the needle valve. It can set and adjust the opening and closing speed, delay time, and other parameters of the needle valve.

2. Needle valve assembly: The needle valve assembly usually includes a needle valve and a needle cylinder. A needle valve is a movable component located in a mold that controls the flow and stop of plastic material by controlling the movement of the needle cylinder. The needle valve opens during the injection molding process, allowing hot plastic material to enter the mold cavity, and then closes at the appropriate time to stop material flow.

3. Hot runner components: Similar to other hot runner systems, needle valve hot runner systems also include hot fluid distributors, hot runners, and nozzles. The hot fluid distributor distributes the hot fluid to each hot runner, which guides the hot fluid into the mold cavity. The nozzle is responsible for injecting hot plastic material into the mold cavity.

4. Temperature control: The needle valve hot runner system is also equipped with a temperature controller for monitoring and regulating the temperature of the hot fluid. The temperature controller can monitor and adjust the temperature of the needle valve and hot runner in real-time to ensure precise control of the flow and solidification of plastic materials.

The display format of the needle valve hot runner system may vary depending on the manufacturer and mold. Usually, manufacturers provide relevant technical literature, product manuals, or demonstration videos to demonstrate the working principle and operation process of needle valve hot runner systems. If you are interested in needle valve hot runner systems, we suggest that you contact relevant hot runner system suppliers or professional injection mold manufacturers for further consultation and understanding.
