Johnson and Allen Ltd, design and build Aperture Demagnetising Coils for a variety of applications from the Aerospace to Automotive Industries
Standard Aperture Sizes up to 800 x 800 mm.
Custom sizes if required.
Intermittent or Continuous Operation.
Optional Timer Controls
e to Automotive, to Hand Tool production.
Aperture De-mags can be constructed for use with
Conveyor or Roller Track Systems, as well as stand alone units, and those incorporating : -
Runways and Trolleys.

Aperture emagnetisers are fitted with RCD,s and wear plates if required.
Johnson and Allen Ltd will recommend the most economical system to demagnetise components to the required standard (usually 2-3 gauss) but more often than not our machines acheive better than this.
