Co-Rotating / Counter-Rotating Conical Twin Screws and Barrels for Extruder

1 . Descriptions

High mixing and dispersive performance: The intermeshing design of the screws and the optimized screw geometry provide excellent mixing and dispersion, ensuring homogenous and consistent output.

Excellent melt quality: The MCV series of twin screw barrels are designed to provide excellent melt quality, with low shear stress and minimal melt degradation.

High throughput performance: The MCV series of twin screw barrels are capable of processing high volumes of material, with excellent melt conveying and pumping performance.

Modular design: The modular design of the MCV series of twin screw barrels allows for easy customization and adaptation to different extrusion applications.

Plastic extrusion is a manufacturing process that involves melting and shaping plastic materials into a continuous profile or shape using an extruder machine. The plastic materials are fed into the extruder through a hopper and then melted by a heating element, which is typically a single screw or a twin screw.

There are various types of plastic materials used in plastic extrusion, including PE (polyethylene), PS (polystyrene), PC (polycarbonate), ABS (acrylonitrile butadiene styrene), PET (polyethylene terephthalate), PP (polypropylene), and PVC (polyvinyl chloride).

The type of plastic extruder machine used in the manufacturing process depends on the type of plastic material being processed and the desired end-product. For example, a single screw barrel extruder is typically used for processing materials such as PE, PS, PC, ABS, PET, and PP, while a conical twin screw barrel extruder or parallel twin screw barrel extruder is used for processing PVC.

There are many manufacturers of plastic extruder machines that produce single screw barrel extruders, conical twin screw barrel extruders, and parallel twin screw barrel extruders. Some popular manufacturers include KraussMaffei, Battenfeld-Cincinnati, Milacron, Toshiba Machine, and Coperion.
