Cause:
Frequently used HDPE and MDPE accumulate in the cylinder, screw, and spiral mandrill, where they burn and contaminate.
Solution:
This may call for a manual disassembly of the equipment – at least once a year – for proper cleaning.
Using suitable abrasive RAMCLEAN® materials according to the recommended Cleaning Procedure will prolong the amount of time between each disassembly.
Determining the correct RAMCLEAN® solution will be performed by completing the TEG questionnaire or through a Chat conversation with the RAMCLEAN® experts.
Cleaning tips
- When selecting the cleaning material, take into consideration the raw materials and how suitable they are for the cleaning material.
- When handling serious contaminations consider dismantling the die and using an aggressive RAMCLEAN® to clean the extruder. Later add the die and repeat.
