Precision Magnetic Assemblies 
Arnold is a major supplier of magnetic assemblies with manufacturing factories located in the U.S., the United Kingdom, Switzerland and China.
Arnold Magnetic Technologies has established itself as a premier supplier of precision assemblies for the military-aerospace, industrial and reprographics industries. Precision is the important word here: almost all the product manufactured is 100% inspected, much of it on in-house designed, automated magnetic field mapping equipment.
Products
Product lines include everything from simple assemblies to tight tolerance assemblies consisting of many dozens of components and employing Recoma samarium cobalt, neodymium, alnico and ceramic (hard ferrite) magnets. Examples of some of the products manufactured by Arnold follows:
- Rotors which may include sleeves (inconel, stainless steel, composite)
- Dynamically balanced Rotors
- Eddy current rolls which may include Kevlar or fiberglass wraps
- Pump couplings (inner and outer magnet assemblies)
- Reprographic rolls for toner based copier systems
- Latch assemblies
- Voice-coil assemblies
- Beam focusing assemblies such as wigglers and undulators
- NMR assemblies
The four areas of business focus are:
Magnetic Design: Skills utilized in the design of sophisticated magnetic components and precision magnetic assemblies can be applied to solutions for your application.
Des
ign and Development: Custom magnet fabrication, engineering prototypes, magnetic evaluation, production fixtures and systems, reverse engineering, and electromechanical design, just to name a few.
Contract Manufacturing: from relatively simple mechanical assemblies to complex electromechanical parts and components requiring extremely high precision.
Re-manufacturing Consulting: with more than 20 years of experience involved in re-manufacturing, we offer a team of skilled specialists to guide and assist companies in remanufacturing to reduce costs, increase throughput, improve product performance, and enhance quality
Growth of trade into and out of China is a major factor in the U.S. and world economy. The Precision Assemblies Group manufacturing operations, located in Shenzhen, China, include the production of precision magnetic assemblies for reprographic, industrial and automotive applications.
Assembly Capabilities
Our manufacturing range covers large volume production of systems for the automotive industry as well as small series of "High Tech" aerospace products and individual large assemblies for electrical machines. Some examples of Arnold's capabilities are:
- EDM
- ID slicing and grinding
- In house machining of hubs, rotors, cylinders, sleeves
- Magnetic and Thermal Stabilization of magnets
- Rotor Dynamic Balancing
- Sleeving
- Serializing
- Magnetic Characterization
- Magnet fabrication from a large stock of a Recoma samarium cobalt and neodymium in a variety of grades, alnico and ceramic or hard ferrite. This includes magnets for TWT systems.
Design
Even our most sophisticated customers appreciate the assistance an experienced magnet producer can provide.
Design optimization: 3D finite element modeling capabilities combined with an extensive background related to permanent magnet applications and a solid knowledge of the manufacturing processes provide the assistance you may require for an optimum solution.
Some of the more common applications, such as Permanent Magnet Drives, are designed and produced on a routine basis.
Main applications / Market Segments
Permanent Magnet systems are produced for a wide range of industries:
- Automotive sensors, motors or actuators
- Aerospace applications including radially oriented ring systems for gyroscopes
- Oil and Gas industry sensors and drive systems
- In the chemical and food industries, permanent magnet drives provide clean and safe motive power for pumps, blenders etc.
