Parallel Twin Screw Barrel with Building Block Structure and Nitride Hardness ≥950HV

Product Description:

A parallel twin screw barrel is an essential component found in twin-screw extruder systems. Its composition involves two parallel screws that rotate within a barrel. These barrels are specifically engineered to function in conjunction with the screws to facilitate a variety of material processing operations. The screws can either be co-rotating or counter-rotating, although co-rotating configurations are more commonly utilized in applications such as plastic compounding and extrusion.

The barrel itself is often segmented, enabling convenient replacement and customization tailored to distinct processing requirements. The diameter of the screws can vary widely, starting from as compact as 12 mm for small-scale laboratory extruders and extending up to over 350 mm for sizable 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.
