Magnetic shielding – Design and manufacture

Soudupin has been designing and manufacturing magnetic shielding for demanding applications for over 50 years.

Our customers trust us internationally.

Our achievements

Permimphy® (equivalent to Mumetal®) magnetic shielding and 316LN flanges for ultra-high vacuum applications

Permimphy® magnetic shielding and Teflon® non-magnetic elements

Cylindrical Zero Gauss chamber for calibrating magnetic measurements

Magnetic shielding produced for the Galileo satellite

Design and production of a set of 4 magnetic shields for series cryomodules in the SARAF project (CEA)

Multi-layer magnetic shielding for Magnetoencephalography (MEG) applications

Magnetic Shielded Room (MSR)

We produce self-supporting non-magnetic chambers with magnetic fields of less than 30 nT at any point inside. Our robust, lightweight aluminium structures allow our non-magnetic materials to be fixed without deformation, ensuring excellent attenuation of the surrounding magnetic fields.

See our references for Magnetic Shielded Rooms.

We offer two solutions

Design and build or manufacture to your specifications

Designed by our qualified engineers and technicians

Based on customer specifications, we design magnetic shielding, from the choice of material to the determination of the optimized geometry. To meet our customers’ specifications, we use CAD drawing software, magnetic simulation software, theoretical knowledge and extensive feedback.

Manufactured in our workshops

With our 1800m² production workshop, we can handle all types of magnetic shielding shapes (cylinders, boxes, cones, lids, spheres, stamped parts) in thicknesses ranging from 0.3mm to 3mm for a wide variety of applications (see our machinery). A special workshop is dedicated to large-scale shielding assembly.
