Parallel Twin Screw Barrel 38CrMoAlA Nitriding Hardness 950HV

Product Description:

A parallel twin screw barrel plays a crucial role in twin-screw extruder systems. It comprises two parallel screws rotating within a barrel, working together to facilitate various material processing operations. The screws can be co-rotating or counter-rotating, with co-rotating designs being prevalent in applications such as plastic compounding and extrusion.

The barrel, often segmented, is designed for easy replacement and customization to meet diverse processing needs. Screw diameters can vary significantly, ranging from as small as 12 mm for laboratory-scale extruders to over 350 mm for large 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.
