Vacuum Casting Materials
You can choose a wide range of vacuum casting materials depending on the peculiarities of your project. These resins are typically analogs of common plastic materials with comparable performance and appearance. We have grouped our urethane casting materials into general categories to help you make the best decisions for your project.

High Gloss |
Highly reflective surface finish created by polishing the master pattern before mold making. The high-gloss finish offers high transparency useful for cosmetic parts, lenses, and other cleanable surfaces. |
A1, A2, A3 |
|
|
Semi Gloss |
This B grade finish is not highly reflective but offers some sheen. Using gritty sandpaper, you will get smooth, cleanable surfaces between high-gloss and matte. |
B1, B2, B3 |
|
|
Matte Finish |
Vacuum cast parts will have a satin-like finish through the bead or sand blasting of the master pattern. The C-grade finishes are ideal for high-touch areas and handheld components. |
C1, C2, C3 |

Custom |
RapidDirect can also provide custom finishes through additional processes. On request, you can get unique secondary finishes for the best results. |
