What is Low Volume Vacuum Casting?
Colata sottovuoto a basso volume is a specialized produzione 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.
Al suo centro, IL vacuum casting process uses a vacuum chamber to eliminate air bubbles from the mold, ensuring parts have smooth surfaces and consistent dimensions. Questo tecnologia 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
| Element | Purpose |
| 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
IL vacuum casting process at Yigu Technology follows 6 clear steps, optimized for low volume 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 thermoplastics). This pattern defines the final part’s shape and details.
- Silicone Mold Creation: The master pattern is placed in a mold frame, and liquid silicone is poured around it. After curing (4–8 hours), the mold is split to remove the pattern—resulting in a reusable silicone mold.
- Material Preparation: We select the right material (per esempio., poliuretano, thermosetting resin) based on your needs (flessibilità, resistenza al calore, colore). The material is mixed and degassed to remove air.
- Colata sottovuoto: 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.
- Curare: The mold is heated (or left at room temperature, depending on the material) to cure the part. Curing time ranges from 1–4 hours, depending on the material and part thickness.
Demolding & Finitura: The cured part is removed from the mold, and excess material (flash) is trimmed. We then apply surface treatments (per esempio., painting, polishing) secondo necessità (see Section 5).
