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.

Features
Screw Structure and Motion:
Conical Design: The feed section features a larger diameter, while the homogenizing section has a smaller diameter, creating a forced thrust to prevent material overheating.
Counter-Rotation: Two screws mesh in opposite directions, conveying material axially through the screw gap while applying shear force. Ideal for processing plastics like PVC and polyolefins.
Plasticizing and Extrusion Process:
Heating and Cooling: Built-in cast aluminum heaters and cooling fans within the barrel, combined with gradient temperature control technology, precisely regulate the processing temperature range.
Vacuum Degassing: Ensures uniform plasticization and minimizes bubbles and impurities through a vacuum degassing system.
Energy Efficiency and Environmental Protection:
Variable Frequency Drive: Compatible with VFD motors for energy-saving operation.
Waste Heat Recovery: Selected upgraded models incorporate waste heat recovery systems to further enhance energy efficiency.
