PRO-COOL is engineered for high-performance cleaning of extrusion screws and related components used in plastics processing industries. The machine uses a non-destructive cleaning process that effectively removes stubborn material residue while preserving the original structure, hardness, and dimensional accuracy of the screw surface.
Compared with flame burning, incineration, or manual brushing, it avoids high-temperature damage, screw deformation, oxidation, and hardness loss, helping extend component service life and maintain stable extrusion performance.
The universal cleaning structure allows the machine to handle different screw sizes and extrusion accessories. In addition to twin-screw and single-screw extruder screws, the system can clean die plates, breaker plates, shafts, nozzles, mandrels, and other extrusion tooling components.
This flexibility makes the equipment suitable for plastics compounding, masterbatch production, polymer processing, recycling, and other extrusion applications where frequent material changes and regular maintenance are required.
Non-destructive and high-efficiency cleaning for extruder screws.
Universal design to meet the cleaning needs of various screw types.
The screws can be dried with compressed air and given anti-rust treatment after cleaning.
Extremely low water consumption during cleaning; contaminants can be filtered and collected, featuring environmental friendliness and low operating costs.
No toxic fume or smoke generated in the cleaning process. Completely dust-free, safe and harmless, saving time and labor costs.
No need for flame burning, incineration or manual brushing. It avoids screw deformation and hardness degradation caused by high-temperature exposure.
