Investment casting process

Your drawing/3-D-data are the basis for our design engineers to develop a suitable tool for your component.

The production of the cast part starts in the wax room. We use injection tools and machines to produce the wax models.
Afterwards, they are glued together to clusters.

The clusters are dipped in a special ceramic mass and are then coated with sand. This is how the ceramic shell is formed. The pureness and quality of the material is essential for the later component.

After the ceramic shells have dried, the wax is melted out. Then, the empty shells are burned at temperatures over 1000°C. The most important function of the burning is to give the required firmness and stability to the ceramic shell.

The melted metal is poured into the hot ceramic shell.

The most important factors for producing a high quality cast part are:

• analysis of the melt
• casting temperature
• shell temperature

After the poured mass has solidified, the shell is removed. The cast parts are separated, blasted, fettled and possibly heat treated.
They are now ready for dispatch or for a further mechanical treatment.

Each cast part can be mechanically processed and/assembled into a ready to use system, which we do in-house.
