The screw becomes contaminated over time due to burnt polymer which creates carbon contamination mostly in areas of stagnation, sub-pressure and reverse flow.
Cleaning with RAMCLEAN® materials prior to removing the screw, as it is more efficient than external cleaning.
The cleaning procedure must be performed using a filler, polyolefinic based material, such as RAMCLEAN® 101/204/301. On harder cases, use the RAMCLEAN® 800 due to its high viscosity.
Cleaning tips: Raise the operating temperature by 30-50 degrees (according to the equipment’s and material limitation) and remove the screw at this temperature, slowly and carefully.
Determining the correct RAMCLEAN® solution will be performed by completing the TEG questionnaire or through a Chat conversation with the RAMCLEAN® experts.
