Haichen durable screw barrel for using injection molding machine
The screw barrel (also called the screw and barrel assembly) is one of the most critical components of an injection molding machine. It is responsible for melting, mixing, and injecting the plastic material into the mold. Here's a detailed overview of its function, design, and key considerations:
Plasticizing:
The screw rotates within the barrel, heating and melting the plastic material (pellets or granules) through a combination of friction and external heating.
Mixing and Homogenizing:
The screw's design ensures thorough mixing of the molten plastic, creating a uniform melt with consistent temperature and viscosity.
Injection:
Once the plastic is melted, the screw acts as a plunger, moving forward to inject the molten material into the mold cavity.
Pressure Building:
The screw generates the necessary pressure to push the molten plastic into the mold, ensuring complete filling and packing.
We are prefessional production base specialized in designing and manufacturing plastic injection machines and enjoy high reputation in the Plastic machinery industry.
