A parallel twin screw barrel is a vital component in twin-screw extruder systems. It comprises two parallel screws that rotate within a barrel. These barrels are specifically engineered to complement the screws and enable various material processing operations. The screws can rotate in the same direction (co-rotating) or in opposite directions (counter-rotating), with co-rotating configurations being more prevalent in applications such as plastic compounding and extrusion.
The barrel itself is often segmented, allowing for easy replacement and customization to meet diverse processing needs. Screw diameters can vary greatly, ranging from as small as 12 mm for laboratory-scale extruders to over 350 mm for large industrial 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.
