Use with Hot Runners:

  • Clean first screw and barrel using the Ultra Purge Low-E grade until the ejected Ultra Purge appears visibly clean ejecting Ultra Purge on the side.

  • Start to make injection thru the hot runners with the mold close or open until the molded or ejected Ultra Purge appears visibly clean (we suggest to keep the mold open if the molded part is difficult to be ejected from the mold).

  • In “hard to clean” situations, we recommend to increase the hot runner temperature of 20-30ºC (30-40ºF) and to increase the injection molding cycle time.

  • Continue molding until the molded parts appear visibly clean (we suggest to perform at least 4 injection).

  • Load neutral or production material to eliminate the remnants of Ultra Purge within the machine.

  • Begin normal production
