100% Control of Permanent Magnet Service

Based on the automated test platforms, W-testing provides 100% testing and sorting service. Without any large investment, we make it possible for a 100% control of permanent magnet in China even with a special demand of quality.

The automated test service provides:  

  • customized solution referring to the demands of tolerances

  • customized combination

  • classification and sorting referring to criteria

Not only suitable for small or middle sized companies, large companies can benefit from this service as well. There no need to initialize any investment plan. W-testing can help you complete the quality planning with our automated test service according to the specifications.  Even during the product development phase, we can provide our knowledge of quality control for magnetic application,in order to ensure a smooth procurement afterward.  Now we provide the following module:

 

 

Numbering, data base establishment
Magnetization
Surface strength density test
Magnetic moment/flux test
Magnetic axis test
Sorting
seamless connection with part tracking system
interchangeable magnetizers and corresponding coils and tools
expandable number of test points
based on 1- or 3-axis-Helmholtz-coil
based on 3-axis-Helmholtz-coil
expandable number of sorting classes

Application Examples

Magnetic Moment/Flux + Magnetic Axis + Sorting

Sorting product according to the classes of the magnetic moment and axis: this solution overcomes the difficulty of nonuniformity of manual test process (dragging or rotating) and at the same time prevents any error of sorting by operator. Especially it is suitable for precision magnetic sensor component. A 100% quality control and statistical test report give magnet users and suppliers a possibility to have a supervisory control on production.

Surface Strength Desity+ Sorting

Sorting product according to the classes of the surface strength density: this solution overcomes the difficulty of nonuniformity of manual test process (positioning and tilting) and at the same time prevents any error of sorting by an operator. A 100% quality control and statistical test report give magnet users and suppliers a possibility to have a supervisory control on production.                                                                                          

+

Magnetization + Magnatic Moment/Flux + Numbering + Sorting

Sorting product according to the classes of the magnetic moment: this solution is especially suitable for the clients who assemble the magnets on to the positions which are calculated in a program by considering the strength values of magnets. The database of test results can be easily utilized for calculation.
