SFV Screw Elements Precision Twin Extruder Screw Elements For Plastic Extruder

Product Description

The size of the SFV Screw Element is highly customizable to suit the specific requirements of the application. This means that customers can tailor the screw element to their exact needs. In addition to size, the pitch and helix angle of the screw element can also be customized to suit specific applications.
One of the key applications of the SFV Screw Element is for underwater pelletizing. This process involves cutting plastic pellets while they are still submerged in water. The SFV Screw Element is specifically designed to handle this process, ensuring that the pellets are cut to the desired size and shape. This results in high-quality pellets that are suitable for a wide range of applications.
Another important application of the SFV Screw Element is for back pressure maintenance. This process involves maintaining a constant pressure in the extruder barrel to ensure consistent output. The SFV Screw Element is designed to handle this process, ensuring that the pressure is maintained at all times. This results in consistent and high-quality output.
