cylinder liners Industry Knowledge Expansion

A screw barrel cylinder liner is a component of a screw barrel in a plastic extruder. It is a cylindrical tube that is placed inside the screw barrel and serves as a lining or barrier between the screw and the barrel. The purpose of the cylinder liner is to reduce wear on the screw and barrel and to prevent plastic material from coming into direct contact with the metal surfaces of the screw and barrel. It can be made of a variety of materials, such as ceramic, tungsten carbide, or a special alloy, depending on the specific requirements of the application. Cylinder liners are typically replaced when they become worn or damaged, and can be easily removed and replaced as needed.
