Vacuum casting is a manufacturing technique that uses a vacuum to draw liquid casting material into a mold. It differs significantly from injection molding, in which the liquid material is forced into a mold using a screw..

The vacuum casting process offers significant advantages, and is particularly useful for parts with precise cuts or details. The process begins with a master model, produced by 3ERP Using a computer-aided machining center (CNC) Its affiliates, with the possibility of using 3D printing as well. This master model is then immersed in liquid silicone, which cures to become a mold..

After the mold is cut and the master model is removed, it can be used. This step involves pouring the casting resin into the mold, where the vacuum eliminates bubbles and air pockets to ensure a smooth finish..

The resin part is cured in an oven and then removed from the silicone mold after it cools. It can be reused approximately 20 times. Each molded part is an exact replica of the original model. It's an ideal solution for rapid prototyping and small-batch production of high-quality parts..
