Plastic coated magnets that can withstand a variety of chemical agents other than sulfuric acid and nitric acid are called corrosion-resistant magnets. When our existing plastic coated magnets are not suitable for your project, we can also customize plastic coated magnets, whether round, square shape or with counterbore, which can be customized according to requirements. Custom plastic coated magnets need tools, which will increase the cost of magnets. You can choose any color for custom plastic coated magnets.
One of our customers needs a custom-made magnet coated with plastic to be used on the mailboxes box as a door stopper. According to their design drawings, we manufactured the magnets to their satisfaction at the lowest price.Custom plastic coated magnets are the best solution for door suction, and can also be used in meter boxes and cabinets.
An American customer had a project that needed to install counterbore neodymium magnets outdoors. At first, nickel plated neodymium magnets were used. A few days later, the magnets rusted, which affected the project. Knowing this problem, we provided him with custom plastic coated neodymium magnet. The final use effect is very good, the customized plastic coated magnets were reused many times.
Our custom plastic coated magnets are made of PP plastic, and the grade of internal magnets is usually N42. PP plastic has good heat resistance. The product can be sterilized at a temperature of more than 100℃. Under the condition of no external force, it does not deform at 150℃. Embrittlement temperature is - 35 ℃. The chemical stability of PP plastic is very good, and it is relatively stable to all kinds of other chemical reagents except that it can be eroded by concentrated sulfuric acid and concentrated nitric acid.
