ABOUT MAGNETS   >   Uses of magnets

Permanent magnets have a variety of applications in different sectors. Below are only a few examples:

Magnetic holders and clamping fixtures

Holders are manufactured for application in the industry, offices, workshops, stores, households, etc.
They are made of high-quality magnetic materials, steel, and possibly duralumin with a finish of colour varnish, zinc-plating and polished chrome.
A special arrangement of the magnetic circuit ensure the maximum utilisation of magnetic energy.
With a portative force of 30 up to 400 N depending on the type and size.
A special category includes welding holders – a practical aid in welding, bolting and riveting metal structures at various angles. They have a robust design, some types with an ergonomic handle.
We offer the manufacture of special magnetic holders and clamping fixtures to order.

Separation of metal admixtures

Magnetic separators are generally devices for separating the ferromagnetic, usually steel component from a given mixture. It can be a mixture of solid components, liquid and gas medium (air). The application of separators is wide, from the mining and exploitation industry, via processing industries, food, chemistry, plastics, medicinal drugs to agricultural facilities. A separate chapter is made up of separators in recycling waste and recovering secondary raw materials.
  • Separators are capable of sorting anything from screwdrivers and nails to microscopic metal chippings.
  • Graded thermal classes by required operating temperatures (100oC - 120oC - 140oC - 250oC)
  • Supplies of individual parts (magnetic inserts) to complete separator assemblies.

Main types of separator:

Grate separator
This separator consists of several parallel rows of magnetic rods, placed alternately above one another so that any passing metal admixture is bound to come into close proximity of a magnetic rod and get caught. The rods are enclosed in a thin-walled non-magnetic tube. After the rods are pulled out of the tube the metal admixtures will fall off (self-cleaning function). We also supply individual rods for the manufacture of the separator by the customer.

Magnetic filter
The magnetic filter is frequently used for filtering off fine ferromagnetic admixtures in oils, lubricating and cooling liquids, in hydraulic systems, etc. The filter is shaped as a vessel with an inlet and an outlet pipe. An array of magnetic rods is attached to the vessel lid around which the cleaned medium flows.

Magnetic drum
A type of rotating separator with a self-cleaning feature. It consists of a non-magnetic shell inside which a magnetic crescent-shaped insert is situated. The ferromagnetic admixture is pulled to the surface of the rotating drum and released in a position where it can be safely removed from the cleaned medium (bulk material or granulate).

Magnetic roller
Used for separating metal ferromagnetic particles and is placed as the front roller of a belt conveyor. This self-cleaning, highly productive separator can separate inadvertently included steel objects and clean the transported material. The advantage is its low acquisition cost.

Collection of metal chippings, bolts, ...

Everybody knows the situation when a small bolt which is needed for assembly has fallen into an inaccessible space or become lost on the floor. Or you may want to remove fine metal dust or chippings which a traditional vacuum cleaner cannot handle.

Flat magnetic broom
Collects steel filings, chippings, nails, bolts, screws, nuts and other small objects to a distance of up to 5 to 8 cm. After attraction the objects are easily released at the required spot by pulling out the handle and the clean broom is ready for more work.
The broom does not tire or wear out - its magnetic force never fades away.

Magnetic rod collector
Suitable for collecting small steel objects and impurities in poorly accessible spots, narrow gaps, etc.
By pulling out the handle the rod is cleared of metal objects. After repeated insertion the broom is ready for work.

Magnets inside moulds (high-temperature magnets)

In the foundry industry and the manufacture of plastics it is often necessary to hold smaller parts of moulds using a magnet. Given the high working temperatures it is impossible to use "classic" ferrite magnets or FeNdB magnets. However, there are two types of magnets suitable for these applications – SmCo and Alnico magnets. They are mostly used in steel enclosures (see Magnetic holders and clamping fixtures) to increase the magnetic force and mechanical protection.

Office magnets

The application of permanent magnets in offices of all types has many facets – from traditional ferrite magnets via holding magnets with a coloured plastic cover to multicoloured strips and symbols and signage from a flexible magnetic foil.
Magnets with the greatest portative force will hold even an exercise book of standard thickness on a notice board.

Magnetic packing

Magnetic packing profiles are used for sealing shower cubicles and screens, folding and sliding doors, cupboards and sectional furniture, refrigerators, freezer boxes, etc.
They are made from magnetic rubber (magnetic powder with an elastoplastic binder) and possibly in combination with another flexible plastic.

Printing rollers and plates

Magnetic rollers and plates are applied in nearly all print technologies. They are used for easy fixing of the print matrix and its quick replacement. The body of the printing roller or plate contains a great number of very strong magnets which pull the steel matrix toward themselves. The precise position of the matrix on the roller is ensured by alignment pins or grooves on the body of the roller or the plate. The use of glues, tapes, clamps and other fixtures becomes redundant.
