Application
Tapered twin-screw extruders are primarily used for direct forming of pipes, sheets, and profiles from materials such as rigid polyvinyl chloride (UPVC), while also serving as plastic modifiers and pelletizers for powder materials. With different molds, they can directly extrude sheets, pipes, and profiles for experimental purposes.
