Magnetic and mechanical functions
intelligently combined
Application-specific magnetic compounds for efficient functional components
Max Baermann develops customized magnetic compounds for maximum geometric and magnetic design freedom in the production of functional components. Whether for robotics, automobiles, household appliances or technical pumps and motors, we match polymer binders and fillers precisely to the magnetic, mechanical and thermal properties your application requires – and can even provide heavy rare earth free solutions. We supply the custom magnetic compounds as ready-to-mold pellets or as near-net-shape components for sensors, rotors, actuators and other industrial applications. Discover the benefits of working with Max Baermann.
Polymer binders:
- polyamide 6 (PA6)
- polyamide 11 (PA11)
- polyamide 12 (PA12)
- polyphenylene sulfide (PPS)
Magnetic fillers:
- strontium ferrite (SrFe)
- neodymium iron boron (NdFeB)
- samarium cobalt (SmCo)
- samarium iron nitride (SmFeN)
Advantages
Magnetic compounds from Max Baermann make it possible to achieve …
mechanical and magnetic functions in a single production step
precise magnetic functional components – even with complex geometries
application-specific magnetization patterns with tight tolerances
multipole or locally adapted magnetic field profiles within the component
lower eddy current losses than solid sintered magnets*
independence from heavy rare earths and Chinese supply chains*
near-net-shape manufacturing (less finishing and fewer bonding/assembly processes)
low product carbon footprint compared with sintered magnets
*depending on the filler
Processing options and fields of application for magnetic compounds
Magnetic compounds from Max Baermann are the basis for efficient sensors, rotors and actuators in automotive technology, robotics, automations, consumer electronics, power tools, pumps and more. To achieve this, we first process our compounds into highly filled pellets using a co-kneader or twin-screw extruder, from which we then form near-net-shape components by injection molding. The magnetic function is thus integrated directly – there is no need to glue magnet blocks in afterwards.
Depending on the application, we produce magnets with our magnetic compounds directly as single-, two- or multi-component solutions
- as an insert solution for overmolding inserts such as shafts, bushings or metal cores, or
- as an overmolding solution applying an additional magnetic layer to existing components.
- As a single magnet for individual customer-specific in-house further processing by gluing or overmolding
Good to know: we also develop special compound formulations to obtain drinking water approval for your magnetic components and for applications with rapid temperature fluctuations.
