For most accessories of our new collection we use the centrifugal casting method. Here we put the prototype into a special rubber mass in order to get a casting mold.
This mold is clamed into a rotating machine and then we fill in a special metal alloy. This alloy is known under the name
of ZAMAK, which mostly consists of zinc, aluminum, magnesium and copper. During the running of the machine, the alloy is being spread regularly in the mold by the
centrifugal forces.
This way we get raw accessories which are broken off the casting ring by machines.
This is done in rotating barrels which are filled with a special polishing granulate.
After a final cleaning this raw material can be worked on directly in the electroplating.
What needs to be considered when using the centrifugal
casting method?
The surface of an accessory cannot be cast completely smooth. There is always an uneven structure. This effect can specially be seen on the big and clean surface of a flat label. If this is only on the backside of a label, and the front side is decorated by a Rhine stone, this problem becomes less obvious.
Advantages of the Centrifugal casting method:
As the casting mold can be produced very quickly, this method is ideal for the development of new or the modification of existing
accessories.
Another advantage is the low material costs. Most time the
pro rata tool costs are below EUR 100,-.
The tool is limited in its maximum size. That is why the centrifugal
casting method is mostly used for the production of small and medium quantities.
