Making
Rigid Molds With Fast-Cast Urethanes |
 |
 |
|
Ideal
for smaller models/molds with a flat side,
fast-cast urethanes are widely used for their
ease of
use, low
cost,
and quick
demold
times. However, their use requires careful
application of release agents.

Urethane
Rubber Molds |
 |
|
|
Urethane Rubber molds are widely used when a
flexible mold material is required and a more
expensive or less abrasion-resistant silicone
rubber is not desired. However,
their use requires careful application of release
agents.

 Simple
Silicone Rubber Molds (no parting line)
|
 |
|
| Ideal
for smaller projects (less than 12" x 12"),
this is the easiest process for creating parts,
patterns, tools, & molds. We demonstrate
creating a silicone rubber mold and then the
casting of
parts with Repro, epoxy casting resins and polyurethane
elastomers.

Two-Part
Silicone Rubber Molds (with a parting line) |
 |
|
| When
mass casting a part without a flat side, you must
create a two-part mold. We create a two-part silicone
rubber mold with a clean parting line and then
cast the part with Repro.

Casting
Thin-Walled Parts |
 |
|
Casting
thin-walled parts follows a similar process
to the mass casting video above. However,
this project requires important differences
in venting, gating, and the use of pressure.

Casting
Molds & Models With
Intricate Detail |
 |
|
The
more detailed your patterns, the more difficult
it is to cast void-free molds and models. There
we show you a few tricks to get consistently
better results when working with highly detailed
castings.

Moldmaking
With Clear Silicone Rubber |
 |
|
When
a project requires a complex parting line,
it is often easier to pour the entire mold
in one process with clear rubber, then cut
your parting line. This process also saves
at least a day in creating the mold.

Silicone
Rubber Molds with Complex Parting Lines |
 |
|
|
Sometimes,
a straight parting line simply isn't practical.
Therefore, one must be creative when forming
the two halves of a silicone rubber mold. This
process shows one method for creating
complex parting lines.

Multiple
Cavity Molds |
 |
|
|
When
a project requires numerous duplications, a
multiple cavity mold is created, enabling many
more duplications to be created in a set amount
of time.

Surface Casting |
 |
|
| Ideal
for working on medium-sized projects, this process
of pouring a high quality material around a lower
quality core creates a highly accurate, yet economical
part.
