Customized Ferrites / Air gaps / Special Ferrites / Ferrite machining / Measuring Ferrites

Are you looking for a matching air gap or AL-value for your Ferrite or toroidal core or a customized special ferrite core?

We are machining ferrite cores according to your requirements or design and manufacture totally new shapes and sizes.

Blinzinger - your reliable partner in ferrite cores.

Our company has been working with and matching ferrite cores to customers' specifications and requirements for more than 30 years. We are a reliable supplier for our customers and fulfil assigned tasks fast and flexible. We can modify virtually any shape of core.

- Manufacturing of new shapes and sizes, ferrite machining, ferrite reworking, ferrite cores with air gap, mechanical air gap or according to AL-value, air gap altering, special ferrites, electrical measuring of ferrites, bonding ferrites, separating ferrites (segmenting toroidal cores), Slotting toroidal cores and a lot more in relation to ferrite cores

Ferrite machining - our possibilities

Air gaps

  • Inserting high-precision air gaps (grinding air gap) to mechanical dimensions (minimum tolerances) or AL-value
  • Measuring/testing of ferrite cores according to different parameters: with our vast variety of measuring instruments (like LCR meter (4284A), Power Loss Tester (Blinzinger BVM20), Power Choke Test unit and climatic chamber) measurements can be performed in a wide frequency band or voltage range respectively and under operating on-load conditions.
  • Special air gap / Inserting of high-precision air gaps in form of steps, pitches, slants, caps, slots etc. to influence the modulation
  • Separating toroidal core transformers, segmenting toroidal core transformers (complete separation of toroidal cores)
  • Toroidal core with air gap, slotting toroidal cores with high-precision gaps, e.g. for Hall sensors, (toroidal core with slot or slotted toroidal core to alter the AL-value)
  • Air gaps in pot cores (p-cores)
  • Drilling ferrite cores - drilling of ferrite cores to make drill hole spacing's or opening existing drill-holes with minute deviations (centred) e.g. axis for rotary signal transmitter, enlarging of the central hole of RM-cores or insertion of openings to encapsulate windings

  • Bonding ferrites using adhesives especially suitable for this purpose
  • Printing the cores with the data you need (such as AL-value, air gap, date of manufacture, etc.)
  • Manufacturing of winding goods (measurement coils) for customized calibration of the ferrite cores
  • Following customer request, items can be despatched in ESD packaging (trays or blister)
  • Following customer request, quality control of the ferrite cores with digital microscope, e. g. for aerospace technology

And of course we also machine ferrite cores that you supply to us.

New shapes / Special ferrites / Custom-build ferrite shapes

But we don't just specialise in inserting air gaps or reshaping standard cores; we also machine completely new core shapes, or existing shapes but to new dimensions. We can manufacture these entirely to our customers' requirements - in small quantities or in millions.

Above all, our strengths are

  • Customised developments and special products
  • Full consultation service
  • High quality standard
  • Short delivery time
  • Favourable prices

Applications for these ferrite cores include everything from micro components for the telecommunication and automobile industries to very large components, for example, for machine building or medical engineering.
