Nothing improves the effective output of production more than a reduction of the rejection-quota. Therefore we have developed, together with external authorities such as the casting specialist Klaus Wiesner, a new technology that clearly improves casting quality, even with difficult moulds:

The VIBRATION CASTING TECHNOLOGY (patent pending)

The tests with different gold* and silver** alloys vouch for a more uniform structure, increased stability, a clear reduction in porosity as well as a granular size in the metallic microstructure that is on average halved. For the operator this means: the danger of fissuring is reduced, the postprocessing outlay is decreased and the casting is considerably more resilient for the further processing, e.g. for soldering, grinding, changing the size of rings etc.

We are glad to present you now the new VC 600 V featuring this advanced technology!

Here are its outstanding advantages point by point:

Advantage No. 1

Halved grain size*, finer alloy structure:
More stability, reduced oxidation, reduced danger of breakage


For the analysis, different jewellery pieces have been casted with a 18 ct gold alloy, all with the same machine. The microscopic picture on the left shows the grain structure of the alloy without vibration, the right one shows the result with vibration casting. As you can see at first sight, with the vibration technology the grain size is reduced for more than 50 %! *AU 18ct: Au 750, Ag 128, Cu 122


With a simple example we can explain the real effect of a halved grain size:

Cube with 10cm elements: 1.000 elements Contact surface: 540.000 cm²

Cube with 5cm elements: 8.000 elements Contact surface: 11.000.000 cm²


Imagine a cube of 1,00 m x 1,00 m x 1,00 m, composed with 10 cm cubes = 1.000 small cubes. Constructed with 5 cm cubes, the large cube contains 8.000 cubes! Even more noticeable is the comparison of the contact holding square measures: With 10cm cubes we get a contact square of 540.000 cm2, with 5 cm cubes however, the contact square increases to 11.000.000 cm2 !


The result for the casting quality: the danger of fissuring is reduced, the post processing outlay is decreased and the casting is considerably more resilient for the further processing, e.g. for soldering, grinding, changing size of rings etc.


Advantage No. 2

Smaller dendrite formation:
Better consolidation attitude, and better material flow

We have also made analysis with popular silver alloys, e.g. AgCu6.5. This alloy is solidificating in a dendritic structure. The formation of long dendrite arms is very often the reason for a bad metal flow especially in the sprue or in narrow parts. The vibration reduces the length of the dendrites and improves this way the metal flow even into finest edges.

Advantage No. 3

Optimized material flow:
Better form filling, even intensified by the shaking effect

You know this effect from filling in any powders in a container or in a bag (e.g. coffee or corn from the mill into the bag) or from working with concrete: by shaking - "vibrating" - the container the particles are brought closer, you will have less air between the particles, you will finally have a "full measure". Our vibration technology makes use of this effect: The result is a better form filling and a reduced porosity.

Advantage No. 4

Reduced danger of inclusions:
Less casting porosity, reduced shrinking porosity, higher and even density

All the results of the tests have shown a reduced porosity and a higher density. Another positive result: the variation of the specific weights between the different casting processes was clearly minimized.

Advantage No. 5

Fewer waste castings, reduced finishing work, reduced production costs:
The best technology for your know how - just more effectivity!

We have invested work, manpower and capital to develop the best possible technology for you. But we didn't succeed in creating a wonder: your casting knowledge will still be the most important factor to get a perfect casting result, e.g. your know how in the perfect fitting of of the wax models on the sprue and on the main sprue, in the correct mixture of your embedding material and so on. But we can promise: you will always get an optimum result with our vibration technology - under the same conditions a better result as with any other casting system available on the market.
Your most important advantage: better casting quality, reduced scrap castings, reduced finishing work, reduced production costs!
