Due to its special structure and mixing capacity, the three-screw extruder has shown unique advantages in some applications that require a high degree of mixing uniformity. The following are several application cases of three-screw extruders
- High temperature material processing
application case: Processing polyetheretherketone (PEEK) and polyimide (PI)
process overview: - Raw material preparation: Add PEEK or PI granules and additives (such as fillers, lubricants) into the hopper.
- Heating and melting: The raw materials are melted by passing through the heating zone of the three-screw extruder.
- Mixing and plasticizing: The molten materials are mixed and plasticized under the special design of three screws.
- Extrusion: Plasticized material is extruded through a die into the desired shape.
- Cooling and solidification: The extruded product is solidified by cooling water trough or air cooling.
Key equipment: three-screw extruder, heater, mold, cooling system.
Technical points: screw design, heating temperature control, and mold accuracy.
- Biodegradable plastics processing and production process of
biodegradable plastics : - Raw material preparation: Add bio-based polymers (such as PLA, PBS) and additives (such as plasticizers, antioxidants) into the hopper.
- Heating and mixing: The raw materials are melted and mixed evenly through the heating zone of the three-screw extruder.
- Plasticization: The molten material is further plasticized under the special design of the three-screw.
- Extrusion molding: The plasticized material is extruded into the desired shape through a die.
5. Cooling molding: The extruded product is solidified by cooling water tank or air cooling.
