imosh
wholesale can help you every step of the way in turning your jewelry
idea into a finished piece. Whether you provide the original model yourself
or have our talented model maker produce a model for you. You can be
sure that the resulting castings will meet your needs. We offer Lead-Free
casting alloys.
The
casting process begins by "sinking" the original model into
a rubber disc mold. This mold becomes the
master mold and is used to cast enough copies of the original model
to create a production mold. The
number of cast copies required depends on the size of the piece and
amount of space needed between the
pieces so that they will then cast properly during production. The
size of the cast pieces also dictate how
thick the production mold will be and the diameter of the mold. imosh
wholesale is capable of making
production molds as large as 18" in diameter with a thickness
of up to 3".
Once
all of the pieces are positioned in the production mold, the mold
is vulcanized using heat and pressure. This process forces the mold
rubber into every void, capturing all of the detail and surface texture
of your
original model. Vulcanization also "cures" the rubber, making
it firmer and more durable, capable of
producing many, many identical copies of your original model.
Once
the production mold has been completed, it is placed into the centrifugal
casting machine. The casting machine is turned on, spinning the mold
at a high rate of speed. Molten metal is then poured into the center
of the mold and centrifugal force pushes the metal into the cavities
inside the mold. Once the mold cools, it is removed from the casting
machine and the two halves of the mold are pulled apart, exposing
the cast pieces. The cast pieces are then separated from one another
and finished according to the needs of the customer.
