manufacturing.
Whether it's a one of a kind, one piece special
order or production of thousands of pieces from
filigree to buckles, consult with us so that we

Jewelry Casting is a manufacturing process whereby
a liquid material is usually poured into a mold,
which contains a hollow cavity of a desired shape,
and then allowed to solidify. The solidified part
is also known as a casting,
which is ejected or broken out of the mold to finish
the process. Lost
Wax Casting materials are usually precious metals.
Precious
metals Casting is most often used for making
complex shapes that would be otherwise difficult
or uneconomical to make by other methods.
Terminology:
In the casting process the following specialized
terminology is used:
Cope: The top half of the pattern,
flask, mold, or core.
Core: An insert in the mold that
allows the production of internal features in the
casting, such as holes.
Core print: The region added to
the pattern, core, or mold used to locate and support
the core.
Drag: The bottom half of the pattern,
flask, mold, or core.
Flask: The rigid metal frame/tube
that holds the investment.
Investment material: The material
that is packed around the pattern and then the pattern
is removed to leave the cavity where the precious
will be poured.
Mold cavity: The combined open
area of the molding material and core, there the
metal is poured in to produce the casting.
Riser: An extra void in the mold
that fills with molten material to compensate for
the shrinkage experienced during solidification.
Gating system: The network of connected
channels that deliver the molten precious metal
into the mold cavities.
Pouring cup or pouring basin: The
part of the gating system that receives the molten
metal from the pouring vessel.
Sprue: The pouring cup attached
to the sprue, which is the vertical part of the
gating system. The other end of the sprue attaches
to the runners.
Tree: the wax or finished poured
metal models.
Runners: The horizontal portion
of the gating system that connects the sprues to
the gates.
Gates: The controlled entrances
from the runners into the metal mold cavities.
Vents: Additional channels that
provide an escape for gases that are generated during
the pour.
Parting line or parting surface:
The interface, which is between the cope and drag
halves of the mold, flask, or pattern.
Pattern: A duplicate of the final
casting.
Draft: The taper on the casting
or pattern that allows it to be easier withdrawn
from the mold.
Core box: The mold or die used
to produce the cores.
Prototyping equipment:
We provide reduced time and cost for jewelry designers
and their clients with state-of-the-art technology.
Our machines build wax
models from computer files using thermoplastics
that are perfect components for investment jewelry
casting.

For precious metals
Our technicians utilize all file types compatible
with any CAM device, which allows us to quickly
generate a precise wax model ready for jewelry
lost wax casting.
