Vacuum casting is a manufacturing technology that uses a vacuum to draw liquid casting material into a mold. It differs significantly from injection molding, which pushes liquid material into a mold using a screw.
The process of vacuum casting offers significant advantages, and is particularly useful for parts that have undercuts or fine details.
The process starts with a master model, which XTJ creates using one of its CNC machining centers — though 3D printing can also be used. This master model is then immersed in liquid silicone, which is cured and becomes the mold.
Once it has been cut and the master model removed, the silicone mold can be put to use. This stage involves pouring casting resin into the mold, as the vacuum removes bubbles and air pockets to ensure a smooth finish.
The resin part is then cured in an oven and removed from the silicone mold after cool down, which can be reused around 20 times.
Each cast part is an exact copy of the original master model. It’s a perfect solution for rapid prototyping and making small batches of quality parts.
