think3D offers high quality industrial casting services in Vacuum Casting machine. Vacuum casting is a casting process for elastomers using a vacuum to draw the liquid material into the mold. With 3D Printing, CNC Machining, Vacuum Casting, Injection Molding services all at one place, we are a truly one-stop shop for your manufacturing needs.

The vacuum casting process starts by placing a two piece silicone mold in a vacuum chamber. The raw material is mixed and degassed and then poured into the mold. The vacuum is then released and the mold removed from the chamber. Finally, the casting is cured in an oven and the mold removed to release the completed casting. The silicone mold can be reused.


We supply a range of storage and curing ovens for materials and moulds. Analogue or digital control can be specified, along with construction materials and supply voltage.

Two ovens are necessary for vacuum casting. The first oven, which is permanently in operation, is for storing the resins, especially opened units, at a temperature of 35°C.  This slight tempering prevents the resin from crystallising, this is especially important for isozynath-components.

A second oven is necessary, because a constant temperature of 70°C is required. The silicone moulds are pre-tempered at this temperature to enable perfect casting results. After the cast the silicone mould is put back into the oven, to temper the plastic part for reaching the optimal final strength.

A vacuum casting machine uses a vacuum to suck the molten metal into the mold. A force is needed to overcome the surface tension of the molten metal. The centrifugal machine must be securely bolted to a level surface with a protective fence around it. A metal washtub or a drum from a clothes dryer can be used.

The advantages offered by plaster casting include: A very smooth surface finish. The ability to cast complex shapes with thin walls. The capacity for forming large parts with less expense than other processes, such as investment casting.

Vacuum casting or vacuum duplication involves injecting a resin into a silicone mould. Because of its cost and deadline, this method is most suited to pre-series, with a faithful reproduction of the original model and a result close to the end result in the “right material”. Vacuum casting technology is recommended for the production of around ten to one hundred parts for mechanical or visual tests.

You can get at least 20 shots out of a silicon mold. After 20 shot, the vacuum casted mold starts to decrease in quality.

It can be molded into finished product by application of heat and pressure.

  • Low weight
  • Corrosion resistance
  • Insulation properties
  • Electrical properties
  • Cheaper
  • Easy to handle
  • Surface properties
  • Reusable

Vacuum casting results in significant economies of scale. It is recommend to use this prototyping technology for quantities exceeding ten pieces. From this number, the cost of creating the silicone tooling is paid off and the technology of vacuum casting generally becomes more attractive than CNC machining.

The tooling consists of a master part and a mould. The economies of scale generally reach their maximum from 100 to 200 prototypes. Beyond this quantity, it is recommended to design an injection mould from aluminium or steel.
