8 Pouring Metal
8.1 Metal Types
The current product offering is ZCast 501 powder and is designed for low temperature, non-
ferrous metals [MAX TEMP 1100
°C (2000°F)]. The higher temperature metals will cause more
gassing on contact with the mold. Use of molten metals with pouring temperatures above the
maximum temperature recommended for the ZCast molds can cause the mold to fail, possibly
explode, and release entrapped gases and molten metal. Do not attempt to pour molten ferrous
metals into ZCast 501 molds.
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.
WARNING
Do not handle molten metal without adequate local exhaust
ventilation. Hot gases emitted during the casting process
can burn skin and are irritating and toxic. Refer to the ZCast
501 powder MSDS for more information.
