Precision magnetic components

We have a large number of in-house manufacturing and value-added finishing business. Our technical application team also has a wealth of expertise in the application of magnetic technology, providing customers with CAD and 2D / 3D simulation support, as well as solution optimization.

We are not only product providers, but also a realizer of your idea. After fully understanding all the requirements of customers, we will carry out the following program verification and product production links:

Prototype verification:

In addition to the daily lean production management control, we spend more energy on prototype verification, model design and scheme optimization. After understanding the overall requirements of customers, Leyun uses 2D or 3D simulation program to verify the prototype to ensure that the specified performance index is achieved under the given conditions, and the optimized magnet size is calculated to reduce the cost.

Manufacturing solution:

Magnets are hard and brittle materials, which are difficult to process. In this process, we focus on how to complete the processing at low cost. The key points of evaluation include:

The magnet should be simple in shape

Ordinary machining means

The assembly process is simple and controllable

Less parts

Design communication, simulation software calculation, drawing review, fixture design, all of these activities are very important to ensure that the design concept can be realized.

According to our experience, we summarize some problems that are easy to be ignored in design and manufacture

Adhesive force

Many magnetic components use glue to stick the magnet to the metal substrate. The bonding force of glue is the key point to control the stability of the product. Among them, temperature, glue amount and speed are the elements to ensure the bonding force.

Adhesion of coating

Sintered NdFeB is easy to oxidize. Electroplating on the surface is anti-oxidation and acid-base resistant. If the coating adhesion is not enough, the product will be invalid.

Magnet resistance

The magnet can bear high pressure load, but it is easy to break when it is in tension and bending force. The magnet can not be used as a structural part, so the pressure load should be preloaded when necessary.

Thread

The magnet is not easy to process, and it is almost impossible to cut the thread on the magnet. The design and installation mode should be changed.
