Rapid Prototyping Vacuum Casting Silicone Molds with Custom Tolerance and Surface Finish
Rapid prototyping 3d vacuum casting silicone molds
Vacuum casting, also known as silicone mold, needs to be applied to silicone mold. That is, the product prototype is processed
using 3D printing or CNC, and then the silicone mold is made under vacuum conditions, and PA, POM, ABS and other materials
are poured under vacuum conditions, so as to copy the same parts as the prototype. It can achieve the strength and hardness
of ABS and other materials, and can also be equipped with colors according to customer requirements.
Advantages and disadvantages of vacuum casting
The vacuum casting production process is relatively manual and includes several steps.
| Master Pattern Manufacturing |
The master pattern is usually manufactured by SLA 3D printing or CNC machining The choice of method depends on the properties and shape of the part to be produced.
|
| Creation of the silicone mold |
The master pattern is used to create the imprint in the silicone mold, which will be used to duplicate the parts in the selected material and color. It is also possible to create different types of surfaces by polishing the mold impressions.
|
| Material preparation and vacuum casting |
The polyurethane material will be prepared and dyed in the selected color if necessary. Then the silicone mold is placed in the vacuum casting machine and the material is injected into it.
|
| Demolding and solidification |
Once the part is cast, the silicone mold is removed and the part is demolded manually. The piece is then put in the oven (a few minutes to a few hours depending on the size of the piece) and the casting operation is repeated several times.
|
| Polishing and application of finishes |
During this last step the piece will be deburred and hand finished, before applying the desired finishes (polishing, painting, marking etc.)

Vacuum Casting Tolerances
|
Description
|
Tolerance Notes
|
| Distance Dimensions |
+/- 0.15 mm or +/- 0.45 mm per mm, whichever is larger, is typical. Irregular or overly-thick geometries may cause deviances or deflection due to shrinkage
|
| Shrink Mitigation |
A shrinkage rate of +0.15% can be expected due to thermal expansion of the liquid, and the response of the flexible mould
|
| Surface Quality |
Surface finish is externally smoothed to a satin or matte surface. Grow lines may be present on internal or difficult-to-access features. Polishing or custom finishes must be clearly defined and agreed upon at the point of order
|
| Feature Definition |
Sharp corners and text may appear slightly rounded
|
The choice between vacuum casting and 3D printing depends on the specific application and requirements of the part being produced.
For small to medium-sized production runs, vacuum casting may be more cost-effective and efficient, especially when using 3D printing
to create the master model. However, for one-off or highly customized parts, 3D printing may be the better option.
