Sand
Casting
Sand casting is used for
production of metal components when high
surface finish is not critical. It is a
high volume production technology which
requires stable foundry patterns, cores
and core boxes. The LOM process is well
suited for the creation of the often large,
bulky patterns and cores used in sand casting.
When up to 100 components are needed, LOM
parts can be finished, sealed, painted and
used directly to create impressions in the
sand.
SLA, SLS and other RP processes
are also used on a smaller scale to generate
Sand Casting patterns.
