It is very often today you’ll find Rare Earth Magnets utilised in making retail packaging. It is generally paper box construction which has a number of movable flaps. Often found in top end kids book collections, DVD collections, or stuff like Craft type kits found packaged in paperboard. It really is considered a better for the hook and loop type fasteners (i.e. Velcro) located in older style boxes.

There are two configurations which needs to be considered.

1) Using two rare earth magnets

2) Using one rare earth magnet, and something bit of ferrous metal

Selecting which solution to choose depends upon a several factors:

Gap – what’s going to are the total distance between the magnet/metal pair
Feel – the amount of force do you need the conclusion user to put on when opening

Due to somewhat fragile nature of rare earth magnets, in most cases recommended that during assembly from the box, the two parts (two magnets, magnet/metal) ‘t be permitted to come in direct hitting the ground with the other person. This will likely minimize any chance the magnet could break due to shock if the box is closed.

Two Magnets – This configuration is the most suitable utilized each time a stronger bond is essential, then when the information is thick, building a larger gap between them. Magnets might be inserted into paper board which is die-cut, or including be surface mounted and laminated over (or perhaps a decorative design, sticker or pad of some sort or other could be placed on the magnet). Interest must be made during assembly to guarantee the polarity is in an attracting configuration. Adaptor Magnet offer rare earth magnets that happen to be marked within the North seeking pole to help with assembly. If magnets are improperly mounted within an opposing configuration, they are going to repel and the box is not going to close. Magnets want to attract to each other really exact manner, therefore, the two magnets must mate together close for that ideal bond to happen.

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

Either way magnet-magnet and magnet-steel configurations the two main factors which use a stronger solution from the bond.

1) The diameter of the magnet. Larger diameter (larger surface areas) of the magnets will yield stronger the bonds.
2) The thickness in the magnet. Thinner magnets won’t have just as much holding strength as thicker magnets.

Just experiment. Try various configurations to your box construction. It might are more effective with one larger pair, or two smaller pairs. When the bond is just too strong, lower the magnets diameter, volume of magnet pairs, or thickness on the magnets or steel.
