The process begins with the creation of a master model, typically produced using CNC machining or 3D printing. The master model serves as the template for the silicone mold. Its quality directly impacts the fidelity of the final cast parts, so precision and surface finish are critical at this stage.
Liquid silicone rubber is poured around the master model to create a flexible mold. After curing, the mold is carefully cut open to remove the master model, leaving a cavity that replicates every detail of the original. The silicone mold's flexibility allows it to capture complex shapes and textures.
The silicone mold is placed inside a vacuum chamber. Liquid resin, often polyurethane or similar materials, is mixed and degassed before being poured into the mold. The vacuum removes trapped air bubbles, ensuring the resin fills every cavity completely and produces parts with smooth surfaces and fine details.
Once filled, the mold is cured in an oven at controlled temperatures. After curing, the part is carefully demolded. This process can be repeated multiple times, with each silicone mold typically yielding 15–25 high-quality parts before degradation affects quality.
Finished parts often require post-processing to meet client specifications. This can include trimming excess material, sanding, painting, plating, or assembly. Some manufacturers also offer surface texturing and printing services to add branding or functional markings.
Vacuum mold casting is highly versatile and is used in numerous industries, including:
- Rapid Prototyping: Quickly producing accurate prototypes for design validation and functional testing.

Vacuum mold casting manufacturers typically use polyurethane, ABS, PP, PC, and other engineering plastics. The process also supports rubber-like materials and transparent resins, providing versatility for different applications.
High-quality vacuum mold casting manufacturers can achieve dimensional accuracy of ±0.15mm/100mm. The surface finish is also excellent, closely replicating the master model's details and textures.
Lead times vary by manufacturer and project complexity, but most vacuum mold casting manufacturers can deliver prototypes or small batches within 5–10 working days.
A single silicone mold can typically be used to produce 15–25 parts, depending on the complexity and material used. After this, a new mold may be required to maintain quality.
Vacuum mold casting is ideal for rapid prototyping and small-batch production because it is faster and more cost-effective than injection molding, especially when only a limited number of parts are needed.
