Thin material has high magnetic attraction
Anchor Magnets has just launched a magnetic product, Mag-Edge(TM), which yields a formidable magnetic strength from an unusually thin and narrow piece of co-extruded material.
Catch holds CD player cover secure
The Kane Magnetics International subsidiary Anchor Magnets of Sheffield, UK, has conceived and developed a magnetic catch assembly that goes into Jaguar's latest X-Type luxury saloons, the X-400.
The benefits of these extruded magnets are many and various.
With them, the transition "from concept to finished product" is very quick and streamlined because (compared with say the injection moulding process) tooling up for prototypes and later production runs takes less than one week and is low in cost.
Complex profiles are so easy to create in the die and then simplicity itself to punch, drill, cut-to-length and overprint.

Kane Magnetics International (KMI) also offers the special facility to injection-mould complex, high-precision, anisotropic, multi-pole components in volume at low cost, in sizes down to 0.5g.
Leading board skills and testing support offered
AB Electronic Assemblies (ABEA) has invested over GBP500,000 to add new services to its portfolio, including bar coding, optical and BGA inspection, finer controls on screen printing and BGA re-work.
The only limit may prove to be the designer's imagination.
Anchor Magnets can orientate polarity to optimise magnetic performance.
And the product retains its magnetism well over a long lifetime.
The company is now introducing in-house compounding of powder and binder for even tighter control over product quality, consistency and properties and for enhanced flexibility and security of supply.
For example: Different powders can fulfil differing energy requirements.
Or a choice of double-sided adhesive backings can be applied to the non-magnetic face of the extrusion to suit the conditions of use.
Typical engineering applications for these extruded magnets have been identified as follows:- - Reed switches on moving components such as cylinders, to register numerically the number of traverses or to compare speeds.
Also reed switches for elevator (lift) floor indicators.
- Hall Effect, non-contact, sensing devices for measuring rotational speed and direction.
- TV tube corrector magnets (to neutralise unwanted local variations in ion beam activity at the rear of the cathode ray tube).
- A method of fastening explosives around the supports of a structure for demolition, to focus the detonating force.
- Seals for shower cubicle and other doors.
- Metals and minerals filtration and separation systems.
- Sound dampening for automotive sub-assemblies.
- Retail security tags for clothes.
- Magnetic spirit levels.
- Magnetic tool racks.
- Visual planning boards.
But, whatever your own particular application for flexible magnetic extrusion may be, the technical sales engineers of Kane Magnetics International will analyse all relevant parameters and demonstrate the best way of adapting the process solution to meet your requirements.
