Needle valve hot nozzle is widely used in injection molding machines, extruders and other plastic processing industry, mainly 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.

In addition, needle valve hot nozzle is also widely used in the chemical and pharmaceutical industries. In these industries, precise control and regulation of liquids or gases is required to ensure product quality and safety. Needle valve hot nozzle can meet these requirements, by adjusting the rotation of the needle valve to accurately control the flow rate and pressure of the liquid or gas, but also can be used to control the rate of chemical reaction and temperature during the process and other parameters.

Needle valve hot nozzle is a component in a hot runner system used to control and regulate the flow and heating of liquids. This hot nozzle is usually composed of a needle valve, heater, sensor and other components, which can 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.

The needle valve type hot nozzle has the advantages of high efficiency, energy saving, environmental protection, etc. It can precisely control the heating temperature and flow of the 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.

 What is the introduction of needle valve type hot nozzle?

In addition, the needle valve nozzle has the following advantages:

Good color change performance, suitable for most plastics, good flow performance, very fine gate marks, etc.

It can leave no residual marks on the gate on the product, and the marks at the gate are smooth.

Larger diameter gate can be used to speed up cavity filling, further reduce injection pressure and reduce product deformation.

Can prevent the phenomenon of wire pulling and salivation when opening the mold.

When the screw of the injection molding machine recedes, it can effectively prevent the backsuction material from the mold cavity.

Can cooperate with sequence control to reduce product weld marks.

No CAM, lever mechanism, cylinder and nozzle embedded in the template hole, so the overall compact structure.

The connection between the parts is simple, and the assembly and replacement are convenient.

Please note that when using the needle valve hot nozzle, special attention should be paid to the temperature control at the gate, if the temperature is too high or too low, it may cause production difficulties. In addition, when installing and using the needle valve type hot nozzle, it is also necessary to pay attention to cleaning up the garbage of each hot nozzle point and checking whether the mold is processed according to the requirements.
