Vacuum Casting. The Bridge to Low-Volume Production.
REBAN specializes in professional Vacuum Casting (Urethane Casting), using high-fidelity silicone molds to replicate production-grade plastic properties. This process delivers 1–100+ parts with injection-molded quality, bypassing the high costs and long lead times of steel tooling.

The Strategic Advantage of Agile Manufacturing
Premium Material Access: Situated in a global manufacturing hub, we utilize elite resins (AXSON/HEI-CAST) and high-tier silicones to ensure your prototypes achieve industrial-grade durability.
Complex Geometry Specialists: We replicate deep undercuts and thin-walled features that are often “un-moldable” or cost-prohibitive in traditional steel tooling.
Cost-Effective Market Entry: Launch batches of 5–500 units without the heavy investment of hard tooling, allowing for low-risk market testing and rapid design iteration.
Insert & Overmolding Capabilities: Our process supports casting around brass inserts, bushings, or existing components to create fully functional, multi-material assemblies.
Vacuum Casting Technical Specification Matrix
| Technical Parameter | REBAN Regional Standard | Engineering Notes |
|---|---|---|
| Material Emulation | ABS, PC (Clear), Nylon (PA66), TPE/Rubber (30A-90A), UL94-V0 Fire Retardant | High-fidelity resins (Axson/Heicast) to match production intent. |
| Dimensional Accuracy | ±0.15mm per 100mm | Standard commercial tolerance; high-precision master patterns used. |
| Max Part Dimensions | Up to 2000mm x 1000mm x 800mm | Supports large-scale industrial housings and automotive panels. |
| Surface Textures | SPI-A1 Mirror, VDI 24-33, MT-Equivalent, High-Gloss Paint, EMI Shielding | Textures are transferred directly from the master pattern with 99% fidelity. |
| Min Wall Thickness | 0.5mm (Small areas) / 1.5mm (Large surfaces) | Ensures full resin flow and structural integrity during vacuum infusion. |
| Embedded Inserts | Brass Bushings, Threaded Studs, Magnets, Electronic Sensors | Hardware is manually positioned within the mold before casting. |
| Lead Time | 3 – 7 Working Days (Batch size dependent) | From CAD approval to first article shipment. |
| Mold Life | 15 – 25 Shots per silicone cavity | Cost-effective for bridge production before steel tooling. |
Design Guidelines for Vacuum Casting (DfM)
- Uniform Wall Thickness: To prevent “sink marks” or warping during the curing process, aim for wall thicknesses between 1.5mm and 4.0mm.
- Draft Angles: While silicone molds are flexible and can handle zero draft, adding 0.5° to 1° of draft significantly extends mold life and improves surface consistency
- Minimum Feature Size: Fine details and text should be at least 0.5mm wide and 0.3mm high to ensure the silicone captures the geometry and the resin fills it completely.
