It is frequently today one will discover Rare Earth Magnets utilized in the creation of retail bundling. This is regularly paper box development which has at least one mobile folds. Regularly found in very good quality children book assortments, DVD assortments, or things like Craft type units discovered bundled in paperboard. It is viewed as a substitution to the snare and circle type latches (for example Velcro) found in more established style boxes. in hộp giấy hcm
There are two arrangements which ought to be thought of.
1) Using two uncommon earth magnets
2) Using one uncommon earth magnet, and one piece of ferrous
Choosing which choice to pick relies upon a few elements:
Hole – what will be the complete distance between the magnet/metal pair
Feel – how much power do you need the end client to apply when opening
Because of the to some degree delicate nature of uncommon earth magnets, it is generally suggested that during get together of the crate, that the two sections (two magnets, magnet/metal) not be permitted to come in direct contact with one another. This will limit any opportunity the magnet could break because of stun when the case is shut.
Two Magnets – This setup is best used when a more grounded bond is required, and when the material is thick, making a bigger hole between them. Magnets can be embedded into paper board which has been bite the dust cut, or they can likewise be surface mounted and covered over (or a brightening plan, sticker or cushion of some kind could be put over the magnet). Cautious consideration should be made during get together to guarantee the extremity is in a pulling in setup. A few makes offer uncommon earth magnets which are set apart on the North looking for pole to help in gathering. On the off chance that magnets are inappropriately mounted in a contradicting setup, they will repulse and the container won’t close. Magnets like to draw in to one another in an extremely careful way, so the two magnets should mate together in nearness for the ideal cling to happen.
Magnet and Steel – This setup is best used when a marginally more vulnerable bond is wanted, the material being utilized isn’t as substantial, or when generally speaking expense is the restricting component. Utilizing steel as the mating piece to the magnet reduces the general expense considerably as steel is a lot more affordable than the uncommon earth magnets. Steel plates, washers and other comparative steel can be utilized as the mating part to the uncommon earth magnet. Another factor which makes the magnet-steel mix alluring is the situation of magnet. Arrangement of the steel piece isn’t as basic as the magnet will pull in well to the steel in the event that it is larger than usual or not focused. Ultimately there are no worries with extremity when utilizing the magnet-metal arrangement, as the magnet pulls in to the steel similarly on either the North or South looking for poles. Steel pieces are mounted in the comparative manners as the magnets and box could be pass on cut and the metal embedded, it very well may be taped in, stuck in, and it very well may be overlaid over for the absolutely imperceptible bond.
For both magnet-magnet and magnet-steel arrangements there are two components which increment the strength of the bond.
1) The measurement of the magnet. Bigger distance across (bigger surface regions) of the magnets will yield more grounded the securities.
2) The thickness of the magnet. More slender magnets won’t have as much holding strength as thicker magnets.
