5. Depowder the part beginning from the top
surface area and working downwards.
Rotate turntable as needed. Remove as
much powder from part as possible.
For
plaster parts do not remove the
supporting powder.
For starch parts
remove supporting powder.
For ZCast
parts, remove all loose powder.
Leave
part in the depowdering unit and let it sit
for 15 minutes with the depowderer on.
6. You will need to lift the starch part up to
depowder the bottom surface of the part.
7. Transfer part into oven. The oven removes
any moisture left in the part. The
requirement for this step will be dependent
on application and infiltration needs.
Drying times are dependent on wall thickness.
Average drying time for plaster and starch
parts:
•
0 - 0.25” (0 - 6 mm) – 60 minutes
•
0.25” - 0.50” (6 - 13 mm) – 90 minutes
•
0.50” - 1.00” (13 – 25 mm) – 120
minutes
•
More than 1.00” (More than 25.4 mm) -
180 minutes
Average drying time for ZCast parts:
•
4-12
hours
•
Drying times will depend on the volume
and surface area of the part(s) and
oven temperature. The parts need to
dry in an oven with a constant air
temperature of 400
o
F (204
o
C). If you
would like to reduce drying time, hollow

WARNING:
Mold preparation and metal
pouring requires adequate ventilation to
ensure that exposures to dust,
particulates, fumes and vapors are
controlled below occupational exposure
limits. Ventilation designs need to meet
each customer’s respective governmental
health and safety requirements. A
reference frequently used by U.S. firms to
comply with OSHA regulations is the
PLEASE NOTE:
Drying starch parts
at a higher temperature may distort
and damage the part.
Technical Tip
– Spin the turntable so
that the part face you are depowdering
is aimed away from the front opening.
This will direct most of the air jet
reflection toward the wall – allowing you
to use a lower setting on the air curtain.
PLEASE NOTE:
Remove all loose
powder from the starch part. Any
powder left on the part will adhere to
the part during oven drying.
