3 . Wax contains oils that may separate over long periods of time in the liquid sates . Stir the wax if it has become stagnate . Dip
the part in the wax . Dip only long enough to cover all surfaces; this should take approximately
20 seconds
for an entire part .
a .
Be careful as the oven and wax are warm . Use tongs or gloves if necessary .
b.
When melting wax it will appear opaque at first but will become translucent over time.
4 . Remove excess wax by placing the part back in the oven . Place the part above the open wax container and let any excess
wax drip off into the container . The part will need to be oriented into two (2) or more positions to clear off the bulk of the wax .
Wrapping the part in the paper towel will speed the process .
a. Parts with small features (cross-sections ≤4mm) must to be kept under
50°C
to prevent distortion .
b . At
50°C
it will take approximately 1 hour for the wax to completely melt off the part .
c. Large robust parts (all cross-sections ≥ 15mm) can be subjected to temperatures up to
60°C
to speed the process .
Dip part in wax . Use gloves or tongs if necessary .
After dipping parts are covered in wax. Keep in oven to let excess wax drip off.
