SILICONE MOLD PREPARATION USING THE
FUSER500 MIXER AND VACUUM PUMP
8
EXPERT TIP:
In this section, you will need a precision scale, a ruler, and super glue.
Custom silicone molds are reusable and can last for many years when properly cared for. They
are incredibly flexible, allowing for sophisticated, detailed casting. Our molds are prepared under
vacuum condition, minimizing imperfections, and resulting in higher quality pieces.
Use the mixing glass to prepare the silicone molding rubber
compound used to fill up the u-shaped mold frame. The quantity
of silicone molding rubber compound needed for each mold
should be calculated based on the u-shaped mold frame’s size:
Width (mm) x Height (mm) x Depth (mm) =
Quantity in grams of silicone molding rubber compound
Height
in mm
Depth
in mm
Width
in mm
Once the quantity is determined, add the catalyst.
Follow the manufacturer’s specifications
to define the amount and how to manipulate the catalyst.
EXPERT TIP:
Additional sizes of u-shaped mold frames may be purchased.
REMINDER:
The built-in sprue former will eventually detach from the
u-shaped mold frame. Glue it back using a drop of super glue.
Attach your jewelry pattern to the sprue former using a drop
of super glue. Make sure to position it leaving at least
¼
inch
from the edges of the u-shaped mold frame.
Enclose the aluminum
u-shaped mold frame using
the two molding panels,
then secure it using a rubber
band. Make sure to align the
panels to the base of the
u-shaped mold frame so that,
when secured together, the
piece firmly stands in the
upright position.
