Vacuum Casting for Flexible and Economic Production
Vacuum casting or urethane casting is a technology that combines silicone molds and a 3D printed master pattern to create short-run, rigid parts with production-level quality. The process hardens thermoplastic polyurethane inside silicon or epoxy molds. The result is vacuum casting parts with the same shapes as the original master models. The final dimensions of the vacuum casting parts will depend on the master model, part geometry, and the material chosen.
As a leading vacuum casting manufacturer, cncjsd offers low-cost fabrication of high-quality plastic parts. This technology eliminates the need for expensive upfront investments. Our vacuum casting services offer the complete solution for creating excellent quality prototypes and low-volume production parts.

Our urethane casting services allow you to incorporate changes quickly for further testing and market launch.
On-Demand Production
Vacuum cast parts are excellent options for custom and first-run production. You can cost-effectively test product quality before starting full-scale production.
Vacuum Casting Tolerances
cncjsd offers a range of vacuum casting tolerances to meet your custom requirements. Based on the master pattern and part geometry, we can reach dimensional tolerances between 0.2 – 0.4 m. Below are the technical specifications for our vacuum casting services.
| Type | Information |
| Accuracy | Highest precision to reach ±0.05 mm |
Max Part Size | +/- 0.025 mm
+/- 0.001 inch |
Minimum wall thickness | 1.5mm～2.5mm |
Quantities | 20-25 copies per mold |
Color & Finishing | Color and texture can be customized |
Typical Lead Time | Up to 20 parts in 15 days or less |
Surface Finish for Vacuum Casted Parts
With an extensive array of surface finishes, cncjsd can create unique surface layers for your vacuum casting parts. These finishes help you meet your products’ appearance, hardness, and chemical resistance requirements. Depending on your material selection and part applications, we can offer the following surface finishes:
| Available Finishing | Description | SPI Standard | Link |
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 cncjsd can also provide custom finishes through additional processes. On request, you can get unique secondary finishes for the best results. D1, D2, D3
