Your drawing is the base for our design engineers to develop a suitable tooling for your component.
It is essential for every cast part to start the journey as a wax model. We use injection tools and machines to produce those wax models. Afterwards they get stick together to clusters.
The clusters get dipped in a special ceramic mass and get coated with sand. This is the way how the ceramic shell gets formed. The pureness and quality of the material is essential for a perfect result.
After the ceramic shells have dried, steam and pressure are used to remove the wax. Then, the empty shells are burned at approx. 1,100 °C. During this step, any residual wax in the shell is completely burned off to get an excellent outcome.
The melted alloys get poured in the shell, the shell is still hot then. Most important factors for producing a high quality cast part are analysis of the pouring, as well as the shell temperature.
After the poured mass has dried, the shell get removed. The cast parts are getting separated, grinded, fettled and eventually heat treated.
As the last step every cast part can get mechanically engineered and / or fixed together to an assembly which we are doing in-house as well.
