It is often today you are going to find Rare Earth Magnets used in the production of retail packaging. This is generally paper box construction which includes a number of movable flaps. Often affecting quality kids book collections, DVD collections, or such things as Craft type kits found packaged in paperboard. It can be considered a replacement towards the hook and loop type fasteners (i.e. Velcro) located in older style boxes.

There’s two configurations which should be considered.

1) Using two rare earth magnets

2) Using one rare earth magnet, then one section of ferrous metal

Selecting which solution to choose is dependent upon a several factors:

Gap – after that function as total distance involving the magnet/metal pair
Feel – just how much force would you like the tip user to utilize when opening

Due to somewhat fragile nature of rare earth magnets, it’s usually recommended that during assembly on the box, which the two parts (two magnets, magnet/metal) not able to appear in direct hitting the ground with the other person. This will likely minimize any chance the magnet could break due to shock when the box is closed.

Two Magnets – This configuration is most beneficial utilized every time a stronger bond is required, and when the pad is thick, setting up a larger gap between the two. Magnets may be inserted into paper board that has been die-cut, or they can also be surface mounted and laminated over (or a decorative design, sticker or pad of some sort could possibly be placed within the magnet). Careful attention need to be made during assembly so that the polarity is within an attracting configuration. Some manufactures offer rare earth magnets that are marked for the North seeking pole to assistance with assembly. If magnets are improperly mounted in a opposing configuration, they’re going to repel and the box will never close. Magnets prefer to attract together in a really exact manner, therefore the two magnets should mate together close for that ideal bond to happen.

Magnet & Steel – This configuration is best utilized every time a slightly weaker bond is desired, the content being used just isn’t heavy, or when sum total is the limiting factor. Using steel because the mating piece towards the magnet cuts the total cost substantially as steel is a reasonably bit less expensive than the rare earth magnets. Steel discs, washers and also other similar steel can be used the mating part on the rare earth magnet. Take into consideration which makes the magnet-steel combination attractive would be the keeping of magnet. Alignment of the steel piece just isn’t as critical because magnet will attract well towards the steel whether it’s over-sized or not centered. Lastly there aren’t any concerns with polarity with all the magnet-metal configuration, because magnet attracts to the steel equally on either its northern border or South seeking poles. Steel pieces are mounted from the similar ways since the magnets and box could possibly be die-cut along with the metal inserted, maybe it’s taped in, glued in, plus it could possibly be laminated over for the totally invisible bond.

Equally for magnet-magnet and magnet-steel configurations there’s 2 factors which increase Adaptor Magnet on the bond.

1) The diameter from the magnet. Larger diameter (larger surface areas) with the magnets will yield stronger the bonds.
2) The thickness of the magnet. Thinner magnets do not possess just as much holding strength as thicker magnets.

Just experiment. Try various configurations for ones box construction. It may well are better with one larger pair, or two smaller pairs. If your bond is simply too strong, lessen the magnets diameter, volume of magnet pairs, or thickness in the magnets or steel.
