2.3 Safety Instructions
Read and follow this safety information to reduce or eliminate the risk of accidents and personal
injuries.
GENERAL SAFETY
WARNING
Do not allow untrained individuals to design or handle ZCast
molds during manufacturing. Only trained individuals with
sand casting design and foundry experience should design
and handle the ZCast molds.
WARNING
Do not bake ZCast molds in unvented ovens. Irritating and
toxic fumes are formed at elevated temperatures during
oven baking. Ovens must be vented to the outside. Refer to
the ZCast 501 powder MSDS for more information on the
irritating and toxic fumes.
WARNING
Bake ZCast molds until all moisture is removed before metal
casting. Residual moisture in the mold can cause the mold
to unexpectedly fail, releasing entrapped gases and molten
metal and causing serious personal injury.
WARNING
Do not use ZCast 501 molds with molten ferrous metals or
other metals with pouring temperatures above 1100
o
C
(2000
o
F). The molds can suddenly fail unexpectedly
releasing entrapped gases and molten metal causing
serious personal injury.
WARNING
Do not handle molten metal without heat-resistant
faceshield, gloves and apron and tools suitable for handling
molten metal in foundry operations.
CAUTION
Depowdering with compressed air will generate airborne
particles. Only trained or supervised individuals should
depowder a mold. Use hood ventilation and safety goggles
or faceshield to protect the eyes and face. Refer to the
ZCast 501 powder MSDS for more information.
DESIGNING MOLDS
WARNING
Improper design of molds can result in the release of molten
metal and personal injury during the metal casting steps.
Only trained or supervised individuals should design molds.
WARNING
Use only ZCast 501 material for the mold sections and cores
for the Combination Method casting technique. Other mold
materials can unexpectedly release molten metal and cause
personal injury during metal casting.
