Pressure Casting. High-Density Material Excellence.
REBAN’s Pressure Casting service is engineered for components that demand superior structural density and flawless surface aesthetics. By applying external atmospheric pressure during the solidification phase, we eliminate micro-voids and ensure complete resin penetration in complex, thin-walled, or high-viscosity material designs.

Strategic Manufacturing Advantage in Pressure Casting
- Advanced Material Access: We utilize elite-tier, high-viscosity resins that are often unworkable in standard vacuum casting, allowing us to replicate the mechanical properties of heavy-duty engineering plastics.
- Micro-Detail Mastery: Pressure casting is the gold standard for parts with intricate textures, sharp knurling, or microscopic text. We ensure 99.9% fidelity from the master pattern to the final part.
- Enhanced Optical Clarity: For transparent components, our pressure process ensures a “crystal clear” result by compressing any internal micro-bubbles that are invisible to the naked eye but affect light refraction.
- Structural Consistency: By maximizing material density, our parts exhibit more uniform tensile strength and impact resistance, making them suitable for rigorous mechanical testing and functional prototypes.
Pressure Casting Technical Specification Matrix
| Technical Parameter | REBAN Industrial Standard | Engineering Impact |
|---|---|---|
| Casting Pressure | 4.0 Bar – 7.5 Bar (58 – 108 PSI) | Forces resin into microscopic features; eliminates subsurface porosity. |
| Material Capability | High-Viscosity Polyurethanes, Glass-Filled Resins, Ceramic-Loaded Polymers | Supports engineering-grade resins that are too “thick” for gravity casting. |
| Dimensional Accuracy | ±0.1mm per 100mm (0.1% linear) | Achieves tighter tolerances than standard VC; reduces post-machining. |
| Surface Texture Fidelity | SPI-A1 Mirror, VDI 12-30, Custom EDM Textures | 99.9% replication of the master pattern; ideal for knurling and fine text. |
| Min Wall Thickness | 0.4mm (localized) / 0.75mm (typical) | Pressure overcomes surface tension to fill ultra-thin cross-sections. |
| Optical Properties | Water-Clear Transparent (Zero Hazing) | Compresses internal micro-bubbles below visual/light-scattering thresholds. |
| Structural Integrity | Unified Cross-Sectional Density | Ensures consistent mechanical strength for functional load testing. |
| Mold Reinforcement | Steel-Backed or Epoxy-Reinforced Silicone | Prevents mold “ballooning” or distortion under high curing pressures. |
Design Guidelines for Pressure Casting (DfM)
- Reinforced Ribs: Use pressure casting to your advantage by designing thinner, more complex rib structures that provide strength without adding bulk.
- Insert Stability: When overmolding inserts, ensure hardware is securely anchored; the increased pressure during infusion ensures the resin fully encapsulates the insert threads for a superior bond.
- Mold Draft: While silicone is flexible, a draft angle of 0.5° to 2° is recommended for high-pressure parts to maintain surface finish quality during de-molding.
