Impeder cores from BOURNS

Impeder cores, rod cores, hollow cores, perforated cores, hollow cylinder cores, impeder rods, pinned rod cores made of soft magnetic ferrite K2006. This power ferrite K2006 for impeder cores is characterized by

  • High Curie temperature and therefore a high application temperature
  • High flux density in the temperature range up to 150 °C
  • Low power losses in the frequency range up to 500 kHz
  • High effective permeability
  • Good frequency stability of permeability up to 1 MHz

Can be used specifically as a standard transformer material for high-frequency welding technology.
This power ferrite is used to concentrate the magnetic flux and thus enables cost- and energy-saving production of tubes. For maximum performance: high-current applications, welding technology, antennas.

Potting compound and casting resin Scotchcast 3M

Impeder rod cores
Impeder rod cores are essential components in high-frequency welding technology, which are used to control and focus the path of the magnetic flux in welding systems. They contribute significantly to increasing welding speed and improving seam quality by improving the efficiency of the welding process. Manufactured from highly permeable materials, they enable effective concentration of the magnetic field on the welding area, resulting in significant energy savings and increased production output.

Our Impeder rod cores play a crucial role in increasing efficiency and precision in production by specifically amplifying the magnetic flux density in the welding area. Thanks to our extensive range, we offer the right Impeder rod core for every application, tailored to the specific needs of our customers.

Ferrite impeder cores for inductive welding

In HF tube welding, a metal strip is formed into a tube in a continuous rolling process. The opposing strip edges are heated up to liquidus temperature using high-frequency alternating current and mechanically joined together.

The alternating current is generated by induction via a coil. The operating frequency of the coil is between 200 and 800 kHz. A ferrite impeder core concentrates the field lines in the area of the joint so that only a relatively small proportion of the sheet is melted.

As the Swiss representative of BOURNS (formerly KASCHKE), ROTIMA is one of the very few suppliers to offer impeder cores.

A modified ferrite material K 2006 is available for this purpose, which is characterized by the following properties compared to the standard material
a high Curie temperature, and therefore a high application temperature
a high flux density in the temperature range up to 150°C
low power losses in the frequency range up to 500 kHz
high effective permeability
good frequency stability of the permeability up to 1 MHz
The ferrite impedance cores are available in 5 different core shapes:

round rod cores (type KR)
flattened rod cores (type KRF)
feathered rod cores (type KRS)
round hollow cylinder cores (type KRH)
feathered hollow cylinder cores (type KRSH)

depending on the core shape in diameters from 3 mm to 95 mm and lengths up to 200 mm.
