What are the most important considerations to make when it comes to selecting a magnet for lifting and material handling applications? Although it might seem like the case, not all magnets are created equally. When using magnets to conduct daily business, getting the right magnet for the job is essential. A wide range of factors is key for selecting a lifting magnet. In short, you must consider the following:
- Material Thickness
- Surface Conditions
- Temperature Rating
- Contact Area
Each of the above factors carries the same weight, meaning they must be carefully thought through to get the best results from the selection process. For instance, if the wrong material thickness is chosen, it could prevent full magnetic saturation, resulting in a lower holding force.
A permanent magnet’s strength is reduced as temperatures increase. It would help if you had the right material temperature for your working environment for ideal operations. When working with rare earth magnets, it is important not to let them exceed temperatures of 175 degrees because it permanently reduces the magnet’s strength. If heat is a factor, consider a ceramic-based magnet known for high-temperature limits (these are suited for burn table applications).
It is also important to consider the floor space considerations and the process flow. These two pieces of information allow designers to create optimal safety and efficient processes.
