Plastic-bonded magnets with a PA or PPS matrix for many different applications are injected directly onto the carrier using injection moulding. In the process, the material shrinkage of the solidifying moulded material, as well as the different expansion coefficients of the material pairings, cause internal tension and can lead to the formation of cracks. When using elastomer-bonded magnets, this problem can be overcome thanks to the high elasticity of the material. In addition, the material forms a chemical compound with the carrier material, which means that no elaborate undercuts are required. MS-Schramberg stands ready to assist you with the mechanical and magnetic design of your components and has the necessary tools for magnetic, mechanical and thermal simulations. We can carry out all of the relevant tests in our laboratories.

A typical application for elastomer-bonded magnets are magnetic pole rings and sensor magnets for position and speed detection as well as rotor position sensors.
Some applications cause plastic-bonded magnets, which are produced using injection moulding and are injected right onto a carrier, to reach their limits. Material shrinkage of the solidifying material as well as different expansion coefficients can cause internal tension and even cracks. That is why MS-Schramberg is adding elastomer-bonded magnets to its portfolio. They offer significant benefits in these cases due to their high elasticity.
