Pros and Cons for Magnetic Springs in Furniture
How we service our customer, help him to finish his idea and optimize the products to meet the efficient cost.
First we have received an client enquiry regarding magnet assembly, they inquired
Length of magnet spring: l.= 80 mm
Diameter: d=9 mm
Return Force: F=20/30 N
Multiple magnetizations on the outer diameter as shown in figure
According to our experience, for a 9mm diameter magnet to reach a return force of 30N, it has to be a sintered neodymium-iron-boron magnet. However, there is no manufacturer in China capable of manufacturing a four-pole magnetic tube.
We have devised a different solution to address this, which is to make and then stack tile-shaped magnets one by one according to the magnetic circuits requested by the client. We provided a rough production process to elaborate on what LEYUAN intends to do.
This proposal allows us to deliver magnetic circuits as requested by the client, and the return force can be tuned through adjusting the thickness of the tile-shaped magnets. However, this proposal was rejected by the client as it was costly.
Second, after having full understanding of the client's intended use for the magnetic tube, we know that the most crucial part of the project is the return force, which allows us room for designing the optimal solution to the problem.
