Hi just wondering if anyone else does injection molding on a Haitian 1600 and could give some advise, I need to no the procedure you would use if you are making a white 45lt Laundry tub.
The company I work for has done this for years but overtime people have forgotten the procedure as it doesn't run that much anymore any help would be appreciated.
We currently use PET and PET master batch at 4% dry that for at least 8hrs in a drier have barrel temps and mold heats up high with injection fast screw back speed slow and back pressure up really high, we get lots of burns black specs and under packing.
Maybe if someone could point me in the direction of a trouble shooting sheet or information would help lots too
Thanks in advance
