Molding a very small lens using PEI or Ultem for the base polymer. Problem is plate out of the Ultem resin on our diamond turned inserts. I know that there are release coatings that could be used and I am looking for anyone who may have this same issue or someone who already found a cure for this. Tool running around 280'F with a melt temperature of 695'F air shot. Using 35% of shot capacity of press. No issues with residence time in barrel base on .3oz. shot press being used. Any help greatly appreciated.
