Product Description:
Introduction to Parallel Twin Screw Barrel
A parallel twin screw barrel serves as a vital element in
twin-screw extruder systems. It comprises two parallel screws
rotating within a cylindrical barrel.
These specially designed barrels function in synchronization with
the screws to facilitate a wide array of material processing
activities.
Versatility and Functionality
The screws in the barrel can either rotate in the same direction
(co-rotating) or in opposite directions (counter-rotating).
Co-rotating configurations are more prevalent, particularly in
processes such as plastic compounding and extrusion.
Segmented Barrel Design
The barrel itself is frequently segmented, enabling convenient
replacement and customization to meet diverse processing needs
effectively.
Wide Range of Applications
Screw diameters vary significantly, with sizes starting from as
small as 12 mm for laboratory-scale extruders and extending to over
350 mm for large-scale industrial applications.
Applications:
Plastic Compounding: Parallel twin screw barrels are widely used
for compounding different types of plastics. This includes blending
polymers with additives like antioxidants, UV stabilizers, and
flame retardants to enhance the properties of the final plastic
product. They are also used for creating polymer alloys, such as
blending polycarbonate (PC) with acrylonitrile - butadiene -
styrene (ABS) to combine the best properties of both materials.
Masterbatch Production: As mentioned earlier, they play a crucial
role in manufacturing masterbatches. By precisely mixing a small
amount of highly concentrated colorants or additives with a base
polymer, masterbatches are produced, which are then used to color
or modify the properties of larger volumes of plastic during the
final manufacturing process.
Plastic Recycling: In plastic recycling facilities, parallel twin
screw extruders with suitable barrel designs are used to process
recycled plastics. The extruder can melt, clean, and compound the
recycled plastic materials, removing impurities and re -
compounding them into usable plastic pellets for further
manufacturing.
