Single Screw Barrel is a crucial component in plastic extrusion machines used to produce various plastic products such as pipes, sheets, and films. The barrel is a long cylindrical chamber that houses a rotating screw. The screw rotates and moves the plastic material through the barrel, where it undergoes heating and melting processes, and is finally extruded into a desired shape. Single Screw Barrel is typically made of high-quality alloy steel or stainless steel, which ensures durability and resistance to high temperatures and corrosive materials.
