What Is Transparent Vacuum Casting?
Fundição a Vácuo Transparente is a specializedvacuum casting technology that focuses on creating clear, defect-free parts usingtransparent casting materiais. Unlike standard vacuum casting, this method prioritizestransparência—eliminating even the smallest air bubbles, impurities, or surface blemishes that could cloud the final part. It’s ideal for applications where visual clarity (por exemplo, light diffusion, product visibility) is as critical as structural integrity.
Below is a simplifiedprocess overview of howfundição a vácuo transparente works, highlighting key steps that ensure clarity:
| Step of Process | Purpose | Key Tool/Material |
|---|---|---|
| Master Pattern Design | Create a smooth, bubble-free prototype (often 3D-printed with high-resolution resin) | Transparent 3D Resin, CNC-Machined Acrylic |
| Silicone Mold Preparation | Make a reusable mold with ultra-smooth cavities to preserve transparency | High-Clear Silicone Rubber |
| Material Mixing & Degassing | Blendtransparent resin and remove air bubbles (critical for clarity) | Vacuum Degassing Chamber, Transparent Casting Resin |
| Fundição a Vácuo | Inject degassed resin into the mold under vacuum to avoid trapped air | Industrial Vacuum Chamber |
| Cura & Demolding | Cure resin at controlled temperatures to maintain clarity; demold carefully to avoid scratches | Temperature-Controlled Oven, Non-Stick Mold Release |
| Precision Finishing | Polish surfaces to enhance transparency and remove any minor imperfections | Micro-Polishing Tools, Clear Coating |

The Transparent Vacuum Casting Process (Step-by-Step)
Creating clear parts withfundição a vácuo transparente requires careful attention to detail at every stage. Here’s a detailed breakdown of our process, optimized fortransparência e precisão:
Demolding & Acabamento: The part is gently demolded to prevent scratches. We then polish the surface with micro-abrasives to enhance transparência and apply a clear protective coating if needed (por exemplo, for scratch resistance).
Master Pattern Creation: We start with a high-precision master pattern—usually 3D-printed with a transparent resin or machined from acrylic. The pattern must be completely smooth (no scratches or layers) to ensure the mold captures every detail without imperfections.
Silicone Mold Making: We pour high-clear silicone rubber over the master pattern and cure it in a controlled environment. The silicone is chosen for its ability to replicate fine details and maintain a smooth surface—key for preserving transparência in the final part.
Resin Preparation: We select the right transparent casting resin (based on your needs: flexibilidade, resistência ao calor) and mix it with hardeners. The mixture is then placed in a vacuum degassing chamber for 15–20 minutes to remove all air bubbles—even tiny bubbles would ruin clarity.
Fundição a Vácuo: The degassed resin is injected into the silicone mold, which is inside a vacuum chamber. The vacuum ensures the resin flows into every corner of the mold without trapping air, creating a bubble-free part.
Controlled Curing: The mold is placed in a temperature-controlled oven to cure the resin. Curing time (1–3 hours) e temperatura (50–80°C) are adjusted based on the resin type to avoid warping or clouding.

| General-Purpose Transparent Resin | Low cost, good clarity, easy to process | 90–92% | Protótipos, bens de consumo (por exemplo, display cases) |
| High-Clarity Polyurethane (PU) Resin | Excellent transparency, impact-resistant, flexible options | 93–95% | Automotive lenses, electronics enclosures |
| Heat-Resistant Transparent Resin | Withstands high temperatures (120–180°C), clarity at heat | 88–91% | Lighting components (por exemplo, LED diffusers), peças industriais |
| Chemical-Resistant Transparent Resin | Resists oils, solvents, e produtos químicos; maintains clarity | 90–92% | Medical devices (por exemplo, fluid reservoirs), lab equipment |
| UV-Resistant Transparent Resin | Prevents yellowing from sunlight; long-term clarity | 91–93% | Outdoor lighting, automotive exterior parts |
Our team helps you select the best material based on your project’s requirements—whether you needtransparência for light diffusion or chemical resistance for medical use.
Surface Treatment for Transparent Vacuum Casting Parts
Transparent casting surface treatment is designed to enhancetransparência, protect against scratches, and improve performance. Yigu Technology offers specialized finishing options for clear parts:
- Micro-Polishing: Uses fine abrasives (1000–3000 grit) to smooth surface imperfections, boosting light transmittance by 2–3%. Ideal for parts where maximum clarity is needed (por exemplo, optical components).
- Clear Protective Coating: A thin, UV-cured coating that adds scratch resistance (tests show a 50% reduction in scratches) and prevents yellowing. Used for parts exposed to wear (por exemplo, automotive interior lenses).
- Anti-Glare Coating: Reduces light reflection on the surface, making parts easier to see in bright environments. Perfect for electronics displays or lighting fixtures.
- Hard Coating: Increases surface hardness (from 2H to 4H on the pencil hardness scale) while maintaining transparência. Suitable for industrial parts that need durability.
All oursurface finishing processes are tested to ensure they don’t reducetransparência—we measure light transmittance before and after treatment to confirm quality.
Tolerâncias & Precision in Transparent Vacuum Casting
Precisão is just as important astransparência in clear-part production—even small dimensional errors can ruin assembly fit or optical performance. Yigu Technology guarantees strictcasting tolerances eprecisão dimensional for every part.
Below is a table of our typicaltolerance levels for different part sizes, using our most populartransparent resin:
| Part Size (Length × Width) | Typical Tolerance | Surface Smoothness (Rá) |
|---|---|---|
| Small (≤50mm × 50mm) | ±0.1mm | 0.02–0.05 μm |
| Medium (51mm × 51mm to 200mm × 200mm) | ±0.15mm | 0.05–0.1 μm |
| Large (>200mm × 200mm) | ±0.2mm | 0.1–0.15 μm |
We use advanced tools like coordinate measuring machines (CMMs) and optical comparators to verify dimensions and surface smoothness. For optical parts (por exemplo, lenses), we also test light refraction to ensure performance meets specifications.
Advantages of Transparent Vacuum Casting
Fundição a Vácuo Transparente offers unique benefits over other manufacturing methods for clear parts—making it a top choice for prototypes and small-batch production:
Consistent Quality: Every part has the same transparência and dimensions, thanks to our controlled process and quality checks. This consistency is critical for industries like medical and electronics.
Superior Transparency: The vacuum degassing and casting process eliminates air bubbles and impurities, resulting in parts with 92–95% light transmittance—comparable to glass but lighter and more impact-resistant.
Cost-Effective: Unlike injection molding (which requires expensive metal tooling), fundição a vácuo transparente uses affordable silicone molds (reusable up to 30–50 times), reducing upfront costs for small batches (10–500 parts).
Fast Lead Times: Silicone molds are ready in 2–3 days, and parts can be produced in as little as 24 hours after mold creation—ideal for rapid prototyping or urgent projects.
Design Flexibility: We can create complex shapes (por exemplo, curved lenses, intricate enclosures) that are hard to achieve with machining. Adjusting designs between batches is easy—no need to retool.
