A "Single-Screw" refers to a type of extruder used in manufacturing processes, particularly in the production of plastics and food products. It consists of a single helical screw that rotates within a cylindrical barrel, helping to mix, melt, and transport materials. This design is efficient for continuous processing and is commonly used in industries like polymer processing and food production. The single-screw extruder operates by feeding raw materials into the barrel, where they are heated and forced through a die to create specific shapes or products. Its simplicity and effectiveness make it a popular choice for many applications, including the production of plastic pellets and snack foods.
