The material for extruder screw cleaning adopts high-efficiency surface active technology, which can effectively improve the cleaning ability. In the extrusion process of the twin screw extruder, only a small amount of cleaning material is needed to clean the carbon deposits and stubborn color attachments on the screw. The cleaning process is very efficient, will not damage the twin screw machine, and will not emit a pungent and toxic smell.
(1) Manually add cleaning material from the discharge port until the extruded strip has the same color and gloss as the washing material pellets, then stop feeding, empty the material, and stop rotating the twin screw extruder screw elements.
(2) Open the die head of the extruder screw and start to clean the screw.
(3) Rotate the screw and take out the pore plate, pour the remaining cleaning material into the barrel, and then clean the pore plate.
(4) Pull out the screw and observe whether it has been cleaned. The residue needs to be removed manually. After cleaning, reinstall the screws back to their original positions, add new material to rinse the remaining cleaning material in the bucket, and then stop the rotation of screw.
(5) Install the pore plate and die head of the twin screw extruder, and then the machine will start trial operation after the extruder screw is cleaned.

Triple flight elements provide strong distributive mixing with lower shear. They are commonly used in melt mixing sections where gentle material distribution is required.
Best suited for:
Melt distribution
Sensitive materials
Low-shear compounding
Liquid Injection Barrel | Twin Screw Extruder Dosing Barrel
Barrel with side feeding port for controlled addition of fillers, fibers or additives during processing.
Best suited for:
Fiber reinforcement
Filler addition
Multi-component compounding
Transition elements are designed to connect different screw element geometries while minimizing dead zones and material retention.
Best suited for:
Transition between single and double flight elements
Connection between SK and standard conveying elements
Geometry change zones within complex screw configurations
Integrated barrel combining feeding and venting functions to optimize space and enhance process flexibility.
Best suited for:
Compact configurations
Combined feeding and venting
Flexible process layouts
Barrel with vent openings enabling efficient removal of volatiles under controlled partial fill and pressure conditions.
Best suited for:
Devolatilization
Moisture removal
Vacuum venting sections
