About how many washes of a Form 4L plate are you able to do before you replace the IPA?
It really depends on the number of parts and the shape of them.
Anyway we though it was saturating too soon so now we have a process of pre-cleaning parts in TPM and scrubbing the excess resin of them to avoid contamination of the Wash L.
With that we are able to nearly double the time between IPA replacement.
Thanks. I am 7 washes in and its at 5.5%. So ~14 washes and replace is sort of unsustainable. I’m scraping resin off the plate before washing.
