The role of the rocket head:
Compress and plasticize the warehouse
The screw head usually cooperates with the structure of the screw (such as the metering section of the three-stage screw) to enhance the compression and plasticization effect on the warehouse, which is conducive to the coordination of the warehouse.

Prevent backflow
The screw head and the check ring (check ring, check ring) and other components prevent the melt that has been plasticized during the injection process from flowing back and ensure the filling pressure during injection.

Improve mixing uniformity
The design of the screw head (such as the volume and shape of the screw head) is conducive to further mixing and homogenizing the plasticized melt, improving the stability and quality of the product.

Enhance shear and mixing
The screw head of a specific shape can enhance the shearing effect on the hopper and improve the dispersion and solubility of the hopper.

Transmit power and pressure
In an injection machine or injection machine, the screw head helps to transmit the rotational force or driving force to the conduit material, pushing the material forward or injecting the mold
