We thought you might be interested in one of the methods we
use for making our plaster moulds. Most of our new designs are
made following a customer request. In this case we received
a request for a single-decker bus similar to our double-decker
plaster mould #2217. We started with a rough sketch, which we
scanned into our computers where we draw what are called vectors
based on the original sketch. |
|
This
rough sketch enables the computer to understand our drawing
and give us the ability to scale it to any dimension and to
allow us to give it a third dimensional shape. |
|
This
computer shaping may take hours or days depending on the complexity
of the design. This design in particular is fairly simple
and only took an hour or so to bring up to 3D. |
|
|
When we have achieved a final acceptable
shape for our plaster mould, we send the file to another computer
and prepare it for machining on our CNC machine.
The machining of our master takes many hours
with multiple drill changes to pick up the fine detail for
which our moulds are becoming well known.

The
photograph above shows the master plaster mould machined in
wood. We now use more advanced materials to obtain even greater
detail. Once the machining is complete the master is mounted,
numbered and prepared for vacuum forming. |
|
Following
a series of tests the master plaster mould is optimized for
maximum strength and test cast several times before we pass
it for sale. |
