Application: Single crystal growth

Pulling up crystal ingots exceeding 300 mm in diameter requires a powerful magnetic field - as used in the MCZ method, the cusped magnetic field method, etc. Rotary feedthroughs used with these techniques must not be affected by their strong magnetic fields.

Our unique rotary feedthrough structure, which is resistant to magnetic fields, has been proven effective in applications involving the pulling up of ingots with a diameter of 400 mm.
