with any mumetal or magnetic shielding questions.
A few short examples of applications
There is a story behind every shielding application. Contracted by NASA to design and build atomic clocks for space exploration, the people at SAO had the opportunity to test Einstein’s Theory of Relativity. Our role was to provide them with some carefully constructed mumetal magnetic shields that are used to maintain the precision of the atomic clocks. Working with minds like this is an honor; as is every opportunity to create a shield design that works.
Our expertise lies in understanding the science of magnetic shielding and providing design and fabrication solutions for a wide range of applications. Typical sources of magnetic interference include:
- Permanent magnets
- Transformers
- Motors
- Solenoids
- Cables
- Earth’s magnetic field
In operation, a mumetal magnetic shield both absorbs and diverts magnetic flux by providing a path around the sensitive area. In addition, shielding is used to contain the magnetic field generated by a device.
MuShield is fortunate to have several design engineers on staff who bring extensive experience in the field of magnetic shielding to the table. In many cases two design minds are better than one, and we work as a team to develop an end product that works. We’re a small company that tackles big problems for our clients. Our flexibility enables us to build, test, and ship prototypes within reasonable time frames to ensure that you get what you need when you need it.
MuShield works closely with customer design engineers to create a viable shield and then build them according to agreed upon specifications, and test for performance. Simple. Effective. Efficient.
Should you have an existing shield design we’ll will provide cost effective production parts. Along with traditional machining capabilities such as metal forming, hydroforming, spinning, and welding, MuShield has talented machine operators specializing in CAM, precision laser work, and tool making. We are fully equipped for production runs; big and small.
MuShield is an industry leader in the fabrication of high permeability mumetal magnetic shields. Our capabilities include:.
- Convention Sheet Metal Fabrication
- CNC Machining and Turning
- Laser Cutting, Machining and Welding
- Hydroforming
- Heat Treating
