Flexible and Reliable Prototypes with Vacuum casting.
Vacuum casting is a flexible and reliable casting process commonly used to generate prototypes and industrial parts. The process requires a high quality master model – this can be the finished industrial part itself, or a model created using Computer Aided Drawing software. Either way, it’s essential that the master model is of perfect quality in terms of both looks and dimensions, so that no flaws are transferred to the prototype/industrial part at the end of the process.

Vacuum Casting Prototypes Look Great
For aesthetic purposes, vacuum casting offers a very high level of reproduction accuracy and finishing options. The process allows for coloring pigments to be added to the vacuum chamber along with the resin components so that your final part will be an exact color match with your company’s branding
Vaccuum Casting is Economical
For short run batches or one-off prototypes, vacuum casting is an economical option, particularly when compared to processes such as plastic injection molding which incur extensive costs due to tooling.
Vaccuum Casting Has Fast Turn-Around
Product turnaround is very fast with vacuum casting, which would make it suitable when company objectives require a part or prototype urgently to move forward and not create a bottleneck in the business stream.
Vacuum Casting is Perfect For Odd Shapes
Vacuum casting would also be a preferable process for creating parts with unusual shapes and small wall thicknesses – other methodologies may struggle to deal with these issues.
Vacuum Casting is the Perfect Solution For Many Applications

Ideal applications for vacuum casting
- Production of plastic prototype parts for a range of industries, including consumer goods
- Prosthetic and medical devices
- Automotive and aerospace parts
- Decorative objects, such as wall plaques or short run custom ornaments
- Part integration and function testing
- Product marketing

Vacuum Casting: How It’s Done
Create the Mold
The master model is encapsulated in a two-part silicone rubber mold and cured at a high temperature.
Hollowed Out
Once cured, the mold is cut open, leaving a hollow area at its center which perfectly matches the dimensions of the master model.
Vacuum Chamber
The mold is now placed in a vacuum chamber and its hollow center is filled with a designated material.
Make it Look Realistic
The material used to fill the mold is usually a polyurethane resin chosen to replicate the specific characteristics of an industrial material.
Final Touches
It is then sealed within the vacuum chamber to prevent any air bubbles from occurring and ruining the final product.
Ready for Production
The resin is cured in an oven and the silicone mold is detached so that it can be reused to create additional prototypes/parts.
