FAQ
*1
Q) Are you a Magnet factory or trading company?
A) We are one of the leading magnet manufactures in Dongguan, welcome to visit our factory.
*2
Q) Does the magnet quality guarenteed?
A) Yes, we can guarentee the magnets we ship to you is of 100% with good quality as you order, if there is any product quality problem or products broken during shipping, we will bear 100% responsibility for you, you can ask for for related refund or replacement.
*3
Q) How long does it take for production and shipping duration?
A) For regular magnet orders, it would take 7-10working days or so, for customized items, it would take 25-35working days or so. Besides, the fastest production time is 3working days for the urgent orders.
*4
Q) How does the magnet grade and magnet dimensions(L x W x H) affects the Gauss Level of magnets?
A) Same magnet size, higher grade with higher gauss;
Same magnet grade, same surface area, the thicker, the higher gauss;
Same magnet grade, same thickness, larger surface area with lower gauss;
*5
Q) What does pulling force mean?
A) Pulling force is a measure of magnetic strength. It is the amount of force required to remove a magnet parallel to a solid magnetic surface, such as a steel plate.
*6
Q) If I stick two neodymium magnets together, does their strength double?
A) No. It will a little smaller. For example, two magnets rated with a individual pulling force of 50 lbs will have a combined pulling force of 90 lbs when stick together.
*7
Q) Do neodymium magnets lose strength over time?
A) They do not naturally lose any strength and will keep the strength permanently in the normal conditions, unless meet the high temperature over 80 degrees Celsius(ºC), and then will lose the strength gradually.
