Vacuum casting is a manufacturing process used to produce high-quality, small-batch prototypes or parts. It involves creating a silicone mold from a master model (typically made via 3D printing or CNC machining) and then pouring liquid resin into the mold under a vacuum. The vacuum removes air bubbles, ensuring the resin fills the mold completely and accurately replicates the master’s details. After curing, the mold is opened, and the part is removed. This method is cost-effective for low-volume production, offering good surface finish and material versatility, often used in product development, testing, or end-use parts.
