WHAT IS EXPECTED FROM AN ELECTROMAGNET?

• To have sufficient holding force, at least equal to the amount claimed, + or – 10%
• To have received very effective corrosion treatment
• To have no residual magnetism even 30 years after continuous use.


WHAT KIND OF ELECTROMAGNETS DO YOU FIND ON THE FIELD? WHAT HAPPENED?

In the first few years following the introduction of our electromagnets in Europe, several competitors emerged, mostly industrial manufacturers, who in Germany and northern Europe launched their own production in their European factories. These products were globally comparable to our own, both in quality and price.
A number of years later, other actors invaded the market, no longer driven by an industrial spirit but purely by commercialism. The only leitmotif was to sell more cheaply a product that looked like the original.


SO HOW DO WE TELL GOOD FROM BAD?

The answer comes from an official laboratory that has tested the main so-called “300 kgf” locks in the European market.

  • STEP 1: The first electromagnet is tested NEW on an axial testing machine in order to find out its maximum strength
  • STEP 2: The same electromagnet is subjected to a salt spray test in another specialist laboratory according to the standards ASTM B 117 / ISO 9227
  • STEP 3: The electromagnet emerging from the salt spray test, representing outdoor usage over a longer or shorter period is tested in the same machine to obtain the residual holding value of a electromagnet rusted as a result of time or its environment.

Test done on our magnets and at the same time to different magnets from our competitors.
