The core position of a twin-screw extruder is undoubtedly the screw, which is to the extruder what food is to humans. The characteristics of the screw at the core position are crucial for the entire extruder. Due to the fact that puffing machinery equipment is known in production, screws are required to have the following characteristics when working with high torque in a highly corrosive environment at high temperatures:

1) Resistant to extremely high temperatures, ensuring that the screw does not deform in high-temperature environments.

2: Wear resistant, the puffing machine works through strong friction between two screws during operation, resulting in a long service life.

3) High strength with hardness and toughness, capable of withstanding high torque and high-speed operation.

4) Corrosion resistance, regardless of the material, has a certain degree of corrosiveness, so the material requirements for the screw are very high.

5) Cutting performance, the edge of the screw body has good cutting ability.

6) Not easily deformed, the screw material after heat treatment has low residual stress and minimal thermal deformation.
