Bunting is a world leader in the design and manufacture of bespoke precision magnetic assemblies and magnetisation equipment.
We are able to supply to all areas of industry, including aerospace, oil and gas, automotive and medical sectors. Our capability for precision magnetic assemblies include large scale static systems up to 1m square and small dynamically balanced, high speed rotary system, produced in our dedicated assembly cells these systems are developed with the customer from the earliest possible stage to ensure they are designed for optimal manufacturing processes.
Our professional services include design for manufacturing, 3D FEA modelling from concept and design optimisation, magnet manufacturing and magnetisation.
Our passion for magnets, excellent customer service, ISO9001 and ISO14001 accreditation make Bunting an excellent long term partner to work with on your future magnetic requirements and magnetic assemblies. We also have the benefits of an unrivaled supply chain allowing us to supply high quality and low to high volume magnet assemblies utilising all grades of permanent magnets.
Value Engineering and Design
We offer a full service to assist in reducing costs and improving the performance of your products as well as design optimisation using the skills of our staff with the latest 3D finite element modelling software.
Technical Magnetic Assemblies
Using our in house machining facilities we are able to produce complex one off design studies to production of parts. Acting as a sub contract assembler, we can utilise our in house machining and assembly skills to reduce the overall cost of magnetic assemblies. This includes Rapid Prototyping, proof of concept and design validation for first off parts.
We design and build magnetising chargers and fixtures enabling us to provide total ownership of magnet supply. We often magnetise post assembly to further reduce the costs and due to our in house ability we are able to do this for low volume production in an economic way.
Design For Manufacture
Design For Manufacture
From the start of the design process our dedicated engineering team will work with you to understand the end application of the project so that they can work as effectively as possible towards a shared goal. Working with your design and engineering team we can support them on;
- Magnetic material choices, when and where to use SmCo over Neo and other magnetic materials.
- Material analysis, from the hard to find magnetic properties of steels to the hystersis curves of the magnet.
- Bonding agents; thin single part acrylics to gap filling epoxies to high temperature adhesives.
- Design for repeatability, ease of assembly or post assembly magnetisation
- Post assembly machining
- And in the case of rotary systems, magnet retention and dynamic balancing.
From the moment that we receive your enquiry, it is important to Bunting Magnetics that are able to effectively communicate the application throughout the business from shop floor to MD. We believe that this integrated approach helps to develop a better level of performance.
A selection of Industries and Applications we service:
Motors / Actuators / Flight Surface Control / Fuel Pumping Systems.

Sensors / Missile Flight Surface Control / Flight Suit Cooling / Jet Reversible Air Turbine
Small Scale Bespoke MRI
- Oil Gas
Debris Capture / Down Hole Pumping / Artificial Lift
Magnetic materials are perhaps best known for their electromagnetic properties but the single biggest factor that affects their use is the low tensile strength of these sintered materials which results in a highly brittle material. The fully saturated magnet is constantly trying to return to a zero energy state but is physically prevented from doing so by the sintering process which locks the magnetic platelets together. With this in mind we work with our customers to develop a design that can be manufactured post assembly so that the risk of damage to people or components is minimised.
With in-house design and development of the magnetising fixtures this is a cost effective low and high volume solution. For one offs and prototypes we have developed bespoke assembly tooling to control the positioning of a magnet relative to a reference point to a high degree of accuracy. This also reduces risk of damage to people or equipment.
Post Assembly Operations
Our goal is to provide a bespoke magnetic assembly that can be easily and safely integrated into your down stream assembly. We can support a wide number of post assembly operations, including;
- Magnetic Tuning
- CNC Machining
- CNC Grinding - Rotary or Flat Bed
- Magnet Retention using metallic or composite carbon fibre systems
- Dynamic balancing.
