                     What is Vacuum Casting? And How 
Vacuum Casting Benefits your 3d printing 
Company…
Vacuum casting is the same as duplication 
using a silicon mold. Plastic vacuum 
casting using silicon molds was developed 
1960s in German universities.
This is a casting process for 
elastomers which uses a vacuum 
to draw any liquid material into the 
mold. Vacuum casting is used 
when air entrapment is a problem 
with the mold.

Vacuum casting process requires you 
to have a high-quality master model. 
The high-quality master model can be 
the industrial part itself. Additionally, 
you can use a model created using 
stereolithography, which is a case for 
the prototyping applications.

After the mold is cured, it is cut open 
to reveal a hollow space at the 
center, which has the exact 
dimensions of the master model. 
After the mold is cut into two, it is 
placed in the vacuum chamber. 
Then, later on, the mold is filled with 
the designated material to make a 
product.

You should fill the mold with the 
designated material. The resin 
replicates the characteristics of 
industrial material. 
The resin material is usually mixed 
with metallic powder or any coloring 
pigment to achieve aesthetic or 
specific functional properties.

The resin is placed in the oven for the 
final cured stage. The mold is cured in 
high temperatures to ensure that the 
material is strong and durable. 
The silicone mold is removed from 
the mold so that it can be used in 
making more prototypes.

Fine Detail To The Finished Product
When you are using silicone as the 
mold to your products. It ensures that 
the final product has great attention 
to the details. The final product ends 
up looking like the original product.

High Quality Of The Product
The products made using the vacuum 
casting method are of high quality. 
Also, the use of resin allows you to 
choose the right material to be used 
in making of the final product.

Lowers The Production 
Costs
Using the vacuum casting process to 
make the product is more 
economical. This is because the 
process uses silicon to make the 
molds.
