(And Live
To Tell About It!)
Making a flexible mold of an original model
will let you make one or many reproductions of that original in a
very short time. However, some have described making flexible
molds as a tedious and frustrating process that is better left to
the pros.
Smooth-On is here to take the guesswork out of making flexible
molds and reproductions (castings) by offering this informative
overview that will introduce the reader to basic techniques as
well as materials available to make flexible molds and rigid
castings.
Questions about these materials, the mold making process or your
specific project can be directed to a Smooth-On distributor
or directly to Smooth-On.
What Is A Mold, Anyway?
Simply put, a mold is a negative impression taken from a positive
model (similar to the negative of a photograph). Your objective in
making a mold is to reproduce an original model as true to the
original as possible. The mold rubber should capture every last
bit of detail, texture, dimension, etc. of the original. And human
nature being what it is, well assume that your objective is
also to make a mold (a) in the least amount of time possible, (b)
with a minimum of difficulty and (c) with as little expense as
possible.
What Are Molds Used For?
Whether or not you are aware of it, molds touch every facet of our
daily life and are used for an endless variety of applications.
Molds are used to create food / dessert designs (Jello mold), for
reproducing original sculpture or ancient carvings. Fossil hunters
and museums and taxidermists make molds of dinosaur fossils,
alligators, fish, etc. to make their reproductions for display.
Candle makers use molds to make an infinite variety of wax
candles. Special effects creators use molds to make models and
figures that make movies spectacular.
Industry uses molds to produce the shoes you wear, the dashboard
in the car you drive, tires on your car, cups you drink from, your
porcelain bathroom sink (sanitary ware), the telephone you use,
decorative moldings that adorn homes, religious and office
buildings, and concrete panels used to construct buildings, etc.
Get the idea?
You Can Make A Mold Of Almost Anything -
Really!
Whether you are interested in reproducing a sculpted
figure, an antique picture frame, an industrial pattern, an
architectural molding, a fossil, animal skin (taxidermy), the
texture of a piece of fabric, or a toy, you start by making a
rubber mold.
Whether you want to make one or one thousand reproductions of an
original, you can do it using a mold. Whether your original model
is made from clay, wax, plaster, sand, concrete, stone, metal,
bone or almost any material, making a rubber mold makes it
possible to reproduce that model exactly.
