TROMADUR®

Cost-effective material based on hard ferrites
Manufacturing process: Injection moulding
Choice of isotropic or anisotropic materials available
The materials used are barium and strontium ferrites (hard ferrites) in various plastic binders

Magnets for rotor and sensor applications:

Plastic-bonded permanent magnets are used in many areas of industry due to their properties.

These include:

Further benefits of TROMADUR® are:

Inserts such as axles or bushings can be included in the production process in a single operation.
Centring collars, anti-rotation devices, holding stays, bases, pinions or similar can be taken into account directly when designing the magnet. This results in simplified assembly and cost savings for the subsequent installation.
low specific gravity
good elasticity properties
magnetic pole patterns from the sine to the approximated rectangular signal are possible
Uniformity of the magnetic signal such as:
- low pole difference
- exact pole pitch
- extreme flank rise
good stability against external magnetic fields
minimum pole spacing with lateral preferred direction
connections with press-in parts without use of adhesives
high displacement forces
marking with parts No. or similar directly during the injection
no mechanical reworking
