Product Description
Double-sided invisible magnetic button clothing waterproof PVC magnet
"Clothing special pvc magnetic button", is specialized for all kinds of coats, coats, trench coats, leather coats, down jackets, raincoats, bags and other clothing products developed. The main function of PVC is to prevent the magnet from playing the role of isolation when it is in contact with water during the use of customers. Long-term contact with water will not rust and oxidation, and will not affect the normal function and appearance. And this "clothing magnetic button" is the biggest highlight is convenient to use, the product is divided into positive and negative poles on the suction, were hidden in the clothes, clothes can not see any button shape, is the so-called "see clothes, no button"! Completely replace the traditional button, more generous, elegant, convenient, fashion. Description: Sealant is transparent PVC soft glue, can be directly stitched with silk, simple and convenient, firm and durable, never demagnetization at 80 degrees Celsius.
How to Customize a Magnet
How to choose the grade of neodymium magnet
Neodymium magnets are graded according to the material from which they are made. The higher the rating (the number after the "N"), the stronger the magnet and the higher the value. The highest grade of neodymium magnets currently available is N54. Any letters after the rating refer to the maximum temperature rating of the magnet. If there is no letter after the grade, the standard temperature of the magnet is 80 °C. Temperature ratings are standard temperature (no letter) followed by - M (100 °C) - H (120 °C) - SH (150 °C) - UH (180 °C) - EH (200 °C) - AH ( 220 °C) C)°C) For example: if the working temperature is 100 degrees, you need to select the H gear, and the temperature resistance of the magnet needs to be higher than the actual use.

custom coating
1. Neodymium magnets are mainly composed of neodymium, iron and boron. The iron in the magnet will rust if exposed to air.
2. That's why all the strong neodymium magnets in our factory are covered with protective coating, the protective coating is very thin (micron level) and has no effect on the adhesion of the magnet.
3. Neodymium magnets are available in many different coating and plating options. The most common coating for neodymium magnets is nickel plating. Although often referred to simply as "nickel plating," this nickel option is actually a three-layer plating consisting of a nickel layer, a copper layer, and a nickel coating.
4. Commonly used nickel (NI-CU-NI), zinc, copper, epoxy resin, gold, silver, passivation, PVC coating, etc.
magnetization direction
The most important thing is to choose the correct magnetization direction
Common directions of magnetization are shown in the figure below:
1>Disc, cylindrical and ring magnets can be magnetized axially or radially.
2> Rectangular magnets can be magnetized by thickness, length or width.
3> Arc magnets can be magnetized radially, by width or thickness.
4>The red in the figure below is the N pole and the white is the S pole
