    Re: Inconsistent surface finish

    Make sure all gates are packing the same around the part and that the mold actual surface temp is relatively uniform if none of the gates have a long flow length then you may be packing more into one...
  5. Re: Cincinnati/Milacron: Opinions on presses & service

    I love milicrons working from 150-3500 ton machines they are my favorites but on the service end I’d agree they are lacking and not very efficient. I hated having a tech touch them there was always...
