There are two configurations that ought to be considered.
1) Using two rare earth magnets
2) Using one rare-earth magnet, and one item of ferrous metal
Selecting which alternative to select depends on numerous variables:
Gap - what will certainly be the total distance in between the magnet/metal set
Feeling - how much pressure do you want completion customer to apply when opening
Because of the rather delicate nature of rare earth magnets, it is typically recommended that throughout setting up of package, that the two components (two magnets, magnet/metal) not be permitted to come in straight contact with each other. When the box is shut, this will minimize any type of possibility the magnet could damage due to shock.
Two Magnets - This arrangement is finest used when a more powerful bond is needed, and also when the product is thick, developing a bigger space between them. Magnets can be put into the paper board which has been die-cut, or they can likewise be surface area placed as well as laminated flooring over (or an attractive style, sticker label or pad of some kind could be put over the magnet). Cautious interest needs to be made during set up to ensure the polarity remains in a bring in arrangement. Some make deal rare earth magnets that are marked on the North seeking pole to aid in setting up. If magnets are poorly mounted in an opposing set up, they will certainly fend off and the box will certainly not close. Magnets like to bring in to each various other in a very exact fashion, so the two magnets will certainly need to mate together close for the optimal bond to happen
Magnet & Steel - This configuration is ideally used when a slightly weak bond is wanted, the product being used is not as hefty, or when the overall cost is the limiting factor. Making use of steel as the breeding piece to the magnet cuts the total price considerably as steel is a fair bit less expensive than the rare earth magnets. Steel discs, washing machines, and various other similar steel can be made use of as the breeding part to the rare earth magnet. One more factor that makes the magnet-steel mix appealing is the placement of the magnet. Placement of the steel piece is not as critical as the magnet will draw in well to the steel if it is over-sized or otherwise centered. Lastly, there are no concerns with polarity when using the magnet-metal setup, as the magnet attracts to the steel similarly on either the North or South seeking posts. Steel pieces are mounted in the comparable means as the magnets as well as the box could be die-cut as well as the metal insert, it could be taped in, glued in, and maybe laminated over for the completely unnoticeable bond.
For both magnet-magnet as well as magnet-steel setups there are two elements that increase the toughness of the bond.
1) The diameter of the magnet. Bigger size (larger area) of the magnets will produce stronger bonds.
2) The thickness of the magnet. Thinner magnets will certainly not have as much holding strength as thicker magnets.
Attempt different setups for your box construction. If the bond is too solid, minimize the magnets size, a number of magnet sets, or the density of the magnets or steel.
Magnets can be inserted right into the paper board which has been die-cut, or they can also be surface area mounted and also laminated flooring over (or an attractive style, sticker label or pad of some kind can be positioned over the magnet). Magnets like to bring in to each various other in a very specific fashion, so the two magnets will require to mate with each other in close closeness for the suitable bond to occur.
Making use of steel as the breeding piece to the magnet reduces the total expense substantially as steel is rather a bit less costly than the rare earth magnets. If the bond is too strong, reduce the magnet's diameter, number of magnet pairs, or the thickness of the magnets or steel.
