  1. Empty the extruder of the production resin. Remove screen packs for the purge if possible. DO NOT REMOVE THE DIE. Raise temperature of the front zone and the die about 35oC above production temperature (but do not exceed the safe processing temperature of the production resin). Make sure any venting- and/or vacuumopenings are closed.
  2. Flush the machine by running clean natural HDPE or carrier polymer (quantity: 1-4 times system volume) to push most of the residual production resin out of the machine (optional).
  3. Load the machine with Econoclean, feeding it directly into the throat. Fill the system until Econoclean mixture is seen emerging uniformly from the die.
  4. Soak the system with the screw turning at minimum RPM for 10 to 15 minutes. Keep the throat full of Econoclean.
  5. Purge the system empty. If the Econoclean still contains many black specks, another cleaning is needed. Raise nozzle and front zone temperature another 10oC and repeat steps 3 and 4.
  6. After setting the desired temperature profile run the new production material through the system until all traces of Econoclean are removed and start up with normal production.

The calculations are based on regular cleaning of the extruder (1½ times net cylinder content). In case of first time cleanings or excessive build-up of burnt material more material will be needed.

Instructions for Injection Moulding equipment

  1. Empty the machine of the production resin; raise nozzle and front zone temperature about 10°C- 15°C above production temperature. (Do not exceed the safe processing temperature of the production resin). Remove the hopper or feed system and make sure all production material is cleaned out of the feed area.

  2. Flush the machine by running clean natural HDPE or a polymer of a higher viscosity than the material to be removed (quantity 1-4 times the nett cylinder content) to push most of the residual production resin out of the machine. Run the machine empty again (optional).

  3. Load the machine with a full system volume of ECONOCLEAN, feeding it directly into the throat. Fill the system until ECONOCLEAN extrudes from the nozzle; keep the throat opening filled with ECONOCLEAN.

  4. Soak the system with the screw stopped for 10 to 20 minutes. Keep the throat full, reciprocating screws forward. ECONOCLEAN will "drool" from the nozzle (the gas pressures of the chemical reaction are pushing it out). If the drooling stops, jog the screw to restore drooling, top off the throat with ECONOCLEAN, and keep reciprocating screws forward. In case of a shut-off nozzle: open nozzle occasionally to prevent excessive pressure in cylinder.

  5. Purge the system empty of the ECONOCLEAN material. If many black specks are seen as the last of the ECONOCLEAN empties from the machine, another cleaning is eeded. Raise the nozzle and front temperature another 10°C and repeat steps 3 and 4.

  6. After setting the required temperature profile run the new production material through the system until all traces of ECONOCLEAN are removed and start up with normal production.
