Product Description:
The parallel twin screw barrel plays a vital role in twin-screw
extruder systems. It comprises two parallel screws that rotate within a specialized
barrel. These barrels are carefully designed to complement the
screws, enabling a variety of material processing functions.
The screws within the barrel can rotate in a co-rotating or
counter-rotating fashion. Co-rotating configurations are more typical in applications such
as plastic compounding and extrusion. The barrel itself is often
divided into segments, allowing for convenient replacement and
customization to suit diverse processing needs.
Screw diameters can vary significantly, ranging from as small as 12 mm for smaller laboratory-scale
extruders to exceeding 350 mm for larger industrial purposes.
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.
