The vacuum casting machine is at the heart of this entire process. It ensures the precise execution of two critical steps: mold creation and resin casting. By maintaining a vacuum, the machine eliminates air entrapment during both stages, ensuring the resin fills the mold completely and uniformly, ultimately resulting in parts with …

Most cost-effective choice: 3D /CNC Machining. Vacuum Casting. Vacuum casting may become less cost-effective and less efficient for high volume production due to the time and cost involved in making multiple molds (each for 15~50 casts). 3D . 3D is still suitable for low volume production.

Vacuum casting is a manufacturing process similar to injection molding where urethane resin is cast in a cavity between two silicone mold halves. The process replicates a master model by pouring a silicone mold around it. In a highly skilled procedure, the mold is sliced into two halves, the master model is removed, and then a gating and ...

Highly detailed, precise components with a fast turnaround. The vacuum casting process begins with creating a master model, typically using high-precision techniques such as 3D or CNC machining. This model is then surrounded by liquid silicone to create a mold. This mold is then placed inside a vacuum chamber.

During the casting process, the pressure increases in the upper chamber to a differential pressure up to 100 mbar. The pressure difference enables the production of very narrow mold cavities with long flow paths. It accelerates the casting process and allows the use of resins with high viscosity, short pot life, and a large portion of fillers.

The vacuum chamber works great with silicone since it sucks out all of the air and the silicone cures slow enough for the vacuum process to complete. On the other hand, most resins start to cure within a few minutes meaning you will end up with a pretty messed up casting when it starts to cure as air is being pulled out.
