Injection plastic molding machine nozzles injection plastic molding spares parts
The injection molding machine nozzle is an important part of connecting the barrel and the mold, and its main functions include:
Establish back pressure: In the pre-molding stage, the nozzle prevents the melt from flowing out of the nozzle by establishing back pressure, ensuring that the melt is fully plasticized in the barrel.
Gas repellent:
The nozzle can expel the gas in the melt during the injection process, reducing air bubbles and defects in the product.
Prevent melt casting:
The nozzle is in contact with the main sprue of the mold, forming a closed flow channel to prevent the melt from overflowing under high pressure.
Improved plasticizing capacity:
Nozzles improve the plasticizing effect of the melt by reducing the shear stress and temperature loss of the melt.
Dosing accuracy:
The nozzle ensures the accuracy of the injection volume by controlling the flow and pressure of the melt.
Heat preservation and material breaking:
The nozzle has a temperature control function, which can keep the temperature of the melt stable, and cut off the melt supply after the injection is completed, preventing the melt from curing in the mold.
Enhance the mixing effect:
The nozzle increases the shear stress by establishing the melt pressure and enhances the mixing effect of the melt.
Temperature control:
The nozzle can adjust the temperature to ensure that the melt is maintained at the right temperature during the injection process.
Reduce viscoelastic effect and eddy current loss:
The nozzle reduces the viscoelastic effect and eddy current loss during the flow process of the melt by optimizing the structural design, and improves the injection efficiency.
Easy to fill the mold during packing: The nozzle can easily fill the mold during the packing stage to prevent the melt from retracting.

The nozzle of the injection molding machine is an important part connecting the plasticizing device and the mold runner, and has a variety of functions, such as establishing back pressure, expelling gas, improving shear stress, temperature regulation, heat preservation and material breaking.
The types of nozzles include interception nozzles, mixing nozzles, fusion nozzles, etc., which are suitable for different injection molding processes and material needs. Interception nozzles can significantly increase productivity and save time in high-speed injection molding.
