Mumetal magnetic shielding
Capital and consumer goods
The need for low-frequency magnetic shielding is found in a wide range of end products, both capital goods and consumer goods, mostly in permimphy.
MECA MAGNETIC intervenes wherever magnetic fields cause an undesired interaction with a sensor, a component, electrons, or an environment, and positions itself as a subcontractor of fine sheet metal work for various applications in various sectors of activity.
We meet the needs of our customers in low frequency magnetic shielding by delivering quality permimphy parts (in unit, small batches or more significant series) at competitive rates, within the given time and in compliance with the plan.
MECA MAGNETIC has a permanent stock of c6 tons of standard references in permimphy with a wide choice of dimensions and thicknesses, integrated heat treatment and treatments adapted to the need.

FAQ
Can you provide us with unitary magnetic shielding without specific industrial constraints?
MECA MAGNETIC is able to address a varied typology of customers and end markets, some of which do not need to meet aeronautical or medical requirements… The operating mode and prices are then in line with the needs and documentation relief, while keeping the quality requirement of the delivered part and the quality of service.
Do you have a buffer stock of material?
Yes, we have a stock of materials that allows us to respond within an optimized timeframe.
Do you make prototypes?
Yes, we usually do in our line of business.
Do you travel to carry out measurements?
In the case of a transformer shielding, where the understanding of the magnetic environment is essential, one of our engineers or technicians will travel before the project in order to characterize the parameters (accessibility, ambient field, operation and constraints of the installation site…).
How are the results checked?
We control the attenuations using our Helmhotz coil or Gaussmeters. On request, we can provide magnetic value readings on control washers from the same batch of material and having undergone the same heat treatment as the parts delivered.
For transformer shielding, a measurement is carried out at the end of the work.
