What is Low Volume Vacuum Casting?
Fundición al vacío de bajo volumen es un especializado fabricación technique designed to produce small batches of parts (typically 1–500 units) using a flexible silicone mold and vacuum pressure. Unlike high-volume methods like injection molding (which requires costly metal tooling), this process leverages silicone tooling to replicate intricate details, making it ideal for pre-production runs, market testing, or replacement parts that don’t require mass manufacturing.
En su núcleo, el vacuum casting process uses a vacuum chamber to eliminate air bubbles from the mold, ensuring parts have smooth surfaces and consistent dimensions. Este tecnología balances precision with cost-efficiency, filling a critical gap for businesses that need quality parts without the expense of large-scale production setups.
Key Elements of Low Volume Vacuum Casting
| Elemento | Propósito |
| Silicone Mold | Captures fine design details and enables repeated use (20–50 cycles). |
| Vacuum Chamber | Removes air to prevent defects like bubbles or voids in the final part. |
| Polyurethane Resins | The most common material—mimics the properties of thermoplastics. |
| Master Pattern | A 3D-printed or CNC-machined model used to create the silicone mold. |

Step-by-Step Low Volume Vacuum Casting Process
El vacuum casting process at Yigu Technology follows 6 clear steps, optimized for volumen bajo efficiency and precision. Each step is managed by our skilled engineers to ensure consistency:
- Master Pattern Preparation: We start with a high-detail master pattern (typically 3D-printed using durable termoplásticos). This pattern defines the final part’s shape and details.
- Silicone Mold Creation: The master pattern is placed in a mold frame, and liquid silicona is poured around it. Después del curado (4–8 hours), the mold is split to remove the pattern—resulting in a reusable silicone mold.
- Preparación de materiales: Seleccionamos el material adecuado. (p.ej., poliuretano, thermosetting resin) based on your needs (flexibilidad, resistencia al calor, color). The material is mixed and degassed to remove air.
- Fundición al vacío: The silicone mold is placed in a vacuum chamber, and the prepared material is injected into the mold. The vacuum eliminates air bubbles, ensuring the material fills every detail of the mold.
- Curación: El molde se calienta (or left at room temperature, dependiendo del material) to cure the part. Curing time ranges from 1–4 hours, depending on the material and part thickness.
Desmoldeo & Refinamiento: The cured part is removed from the mold, and excess material (destello) is trimmed. We then apply tratamientos superficiales (p.ej., cuadro, pulido) según sea necesario (ver sección 5).
