8.2. Cleaning
Clean Mold
Keeping the mold plates clean is vitally important for proper recoat performance and quality. The mold plates should
be cleaned of dirt, dust or excessive recoat material before each use. Clean the mold plates only with a soft cotton
swab soaked in cleaning solution. Acetone is the preferred solution for cleaning the mold plates. Acetone cleans
more thoroughly than alcohol and will also soften and lift away any cured recoat material. Do not use excessive
scrubbing or scraping action to clean the plates. Give the cleaning solution time (60 s- 90 s) to soften and lift any
cured material. Excessive cleaning can shorten the life of the mold through damage to the coatings on the mold
plates or chipping of the mold channel.
To dispose of acrylate material safely, place in a plastic bag and then close the plastic bag with a knot before placing
in the garbage. Alternatively, expose the material to sunlight for four hours and then throw in the garbage.
Check/Clean FHB Inserts
The fiber holding block inserts have a rubber insert that grips the fiber for proof testing. These should be checked
for damage and cleanliness prior to each shift. If the rubber insert is damaged or dirty, the fiber may slip prior to
reaching the maximum proof test level. If required, clean the rubber insert with a cotton swab or lens tissue soaked
in isopropyl alcohol. If rubber insert is damaged it should be replaced.
Note : Do not use acetone to clean the rubber inserts. Repeated cleaning with acetone will damage the rubber.
Note : Do not clean the insert with alcohol when the unit is turned ON. The alcohol could be drawn into the vacuum
system, causing damage.
