Vacuum casting is ideal for duplicating silicone models.
We distinguish between two different molding techniques. Starting from a master model, one option is to create a silicone mold which is then used to duplicate parts made of silicone. A second possibility is the rapid production of a very simple mold via 3D printing. Silicone is then poured into the cavity inside the mold. A variety of silicones with differing Shore hardness are available, as well as food-grade silicone.
The vacuum in the manufacturing process enables us to achieve homogeneous, pore-free material properties. Some of our silicone materials can also be dyed.
Individually and in series
We use original silicones. This makes it possible to use these components as prototypes or as series components. Production either follows the conventional route – from the master model to the casting mold to casting in vacuum – or, for simple components, the parts can be produced directly using a 3D-printed or milled casting mold. From our point of view, 100 to 200 pieces are a sensible batch size for series applications.
With this method, we can produce the first parts within a few working days. Depending on the geometry and material, we can produce small series at a rate of up to 10 components per day.
- Fast implementation
- Cost-effective production
- Fully functional components
- Shore hardness from 10 to 65 Shore A in small gradations
- Wall thickness from 0.5 mm
- Colorable silicone
- Food-grade, bio-compatible materials with FDA certification (not available in every Shore hardness)
We have recently become aware of manufacturers who offer systems capable of 3D printing using silicones. This process involves discharging the material via nozzles or injecting a catalyst into a silicone bath. The selected approach determines whether or not cantilevered components are possible. The layered structure can usually be seen in the components.
For the components that we realize for our customers in silicone casting, we currently see very few application possibilities for these new technologies. Of course, we continuously monitor the latest trends and possibilities, and will inform of you of any relevant developments.
