Pull force is the most important parameter to the shuttering magnet, therefore, shuttering magnet produced by SDM will process 100% pull force testing before delivered. Pull force of shuttering magnet comes from the magnet array which constituted by sintered Neodymium magnets and steel pieces. The drop in pull force is mainly resulted from impurities on the magnet array surface and magnet breakage. In addition to routine cleaning by shuttering magnet cleaner, end users should equip a portable pull force tester to track the pull force. The cost, space requirement, and maintenance difficulty of portable pull force tester has more advantages to users in comparison with the universal testing machine.
