What is Vacuum Casting?
Vacuum casting, also known as silicone or polyurethane casting, is a process that replicates a master pattern using a silicone mold filled with a material such as polyurethane resin under vacuum.
This helps eliminate air bubbles and ensures parts are precise, uniform, and have complex shapes.
It’s ideal for low-volume production and rapid prototyping and can produce parts with surface finishes and mechanical properties similar to those of injection molding.
Industries such as automotive, aerospace, and consumer products benefit from the high-quality, customized products that can be manufactured this way.
With lower tooling costs and quicker turnaround times, vacuum casting is a cost-effective option for companies looking to innovate without breaking the bank.

Vacuum Casting Materials
Explore a range of high-quality materials for vacuum casting, tailored to meet your project’s specific needs and performance requirements.
| Material | Description | Appearance | Subtypes |
|---|---|---|---|
| Soft-rubber-like | Vacuum casting is a great way to make rubber parts and prototypes. The soft, rubber-like materialswork well for parts that need to be flexible and strong, used in both industrial products and thingsfor everyday use. | Colorless Transparent,Yellow Transparent | T0387,8400 |
| PA-like | PX223 is a material similar to nylon, used in silicone molds to make strong, flexible parts that canhandle a lot | Black, Tawny | PX223 |
| ABS-like | Vacuum casting lets you make strong, ABS-like parts that resist impacts and insulate well. Theseparts are often used for electronic casings, car parts, and more. | Beige, Black, Milkywhite | Hei-Cast 8150,PZ858,6160,P+600 |
| PP-like | UP 569o has similar properties to real PP and HDPE materials. It’s easy to work with, strong againstimpacts, and flexible. It’s great for making bumpers, equipment boxes, covers, and tools that reducevibration. | White, Black | T0387,8400 |
| PMMA-like | Urethane casting is a good way to make clear parts. PX-5210 isn’t as clear as real PMMA, but it hasdecent transparency, is easy to polish, doesn’t yellow, and holds up well under UV light. This makesit a solid choice for many uses where clear parts are needed. | Transparent | PX5210 |
| PC-like | PX520 is used in silicone molds to make prototype parts and models that have similar strength andtoughness to real PC (polycarbonate) material.PX520 is used in silicone molds to make prototype parts and models that have similar strength andtoughness to real PC (polycarbonate) material. | White, Clear | PX520 |
Our Surface Finishes for Urethane Casted Parts
Achieving smooth, flawless surfaces—our surface finishes for urethane casted parts deliver both durability and aesthetic excellence.
| Available Finishes | Available Finishes |
|---|---|
| Matte/Frosted | The parts have a smooth, satin finish because the master pattern was bead blasted to a matte texture. Parts that are dear or see- through willook frosted with this finish. Mate finishes are great for areas that are often touched because they hide fingerprints better. |
| Semi-Gloss | Semi-gloss finishes have a litle shine, but not too much Theyre in between shiny (high-gloss) and flat (mate) giving the surface a smooth lookthat’s easy to clean. |
| High-Gloss | A glossy finish with a lot of shine needs the master pattern to be polished before making the mold This finish has a shiny look and makes cearparts look the clearest. High gloss is great for models that need a smooth, clean surface or for lenses. |
| Textured | Texture is added to the master pattern using paint and manual methods before making the mold. Texturing is helpful for areas that get a lot ofuse, like handles, because the bumps and grooves improve grip and reduce fingerprints or scratches. |
| Custom | iBest Proto can also offer extra services like adding finishes, painting, and more. |

Vacuum Casting Tolerances
Discover the precise tolerances we offer with vacuum casting, ensuring your parts meet the highest standards for fit and functionality.
| Description | Tolerance Notes |
|---|---|
| DistanceDimensions | +/- 0.010″ or +/- 0.003″ per inch, whichever is larger, is typical. Irregular or overly -thick geometries may cause deviances or deflection due toshrinkage. |
| Shrink Mitigation | A shrinkage rate of 0.15% can be expected due to thermal expansion of the liquid, and the response of the flexible mold. |
| Surface Quality | Surface finish is externally smoothed to a satin or matte surface. Grow lines may be present on internal or dificult-to-access featuresPolishing 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. |
| Size Recommendation | The maximum part size for vacuum casting is 2000 x 1000 mm. |

FAQs
Is vacuum casting cheaper than 3D printing?
Vacuum casting can be more cost-effective for producing multiple parts, while 3D printingis better for single prototypes.
How does vacuum casting differ from injection molding?
Vacuum casting differs from injection molding based on the type of molds and the volume of production.
On the one hand vacuum casting uses silicone molds and is relied on more for prototyping. On the other hand, injection molding uses steel or aluminum mold and is the best manufacturing process for mass production of parts.
Additionally, vacuum casting is the better option for low-volume projects or prototypes compared to injection molding.
What is the maximum part size for vacuum casting?
The maximum part size for vacuum casting Up to 2000 x 1000 mm.
What are the benefits of vacuum casting for prototyping?
Vacuum casting benefits include excellent balance between cost, speed, and quality when used in prototyping.
It offers the ability to quickly produce functional prototypes with a high level of detail and surface finish.
Additionally, it allows for testing different materials and geometries before moving to large-scale production.
Is vacuum casting permanent?
Vacuum cast parts are durable but not as permanent as injection-molded parts; they are ideal for prototypes or low-volume production.
What is the typical lifespan of a vacuum-casting mold?
A silicone mold has an average life of 10-20 runs before it begins to degrade.
What is vacuum casting used for?
Vacuum casting is used to create high-quality prototypes and small production runs. It’s ideal for parts with complex shapes, detailed features, and is commonly used in industries like automotive, aerospace, medical devices, and consumer electronics.
How accurate are vacuum-cast parts?
Vacuum casting has a accuracy of ± 0.15 % (dimensions below 100 mm bear a lower limit of 0.3mm)
Its precision allows for more detailing and consistency during casting.
What is the vacuum casting process?
The process involves creating a silicone mold from a master model, then injecting liquid resin to produce parts.
What is the cost of vacuum casting compared to other methods?
iBest Proto offers vacuum casting service at a competitive price.
Generally, vacuum casting is cheaper for low-volume production and prototyping than other manufacturing process, e.g., injection molding. However, for high-volume production, it can be less cost effective.
