If there is no moulding case available, it is possible that our toolmaking section builds potting-forms. With a small series, this is cheaper than a die-casting case. Please send a request.

Examples of wage moulding

Potting of piezo ceramic actuators for rotor blades of an helicopter with electric flap drive
|
|
The control is done by three flap modules attached to the backside edge of each rotor blade. The blades have integrated piezo ceramic actuators, which react with a change of length to variable electric voltages. Like this, the rotor flaps are moved about 15 - 40 times per second.
For the future the primary goal of this innovative control method is to reduce the relatively high moises of the rotor blade peak vortex, which are system related for helicopters during the flight. Even though the limits are already underbidden by today, the reduction should reach a level which is clearly below the limiting values of modern Eurocopter-helicopters.
Contemporary the vibrations that have an effect on components and passengers should be decreased remarkable. This will increase the flight comfort and the limit of performance of future helicopters. Furthermore the commercial usage of helicopters will benefit.
