Customized magnets need to know Release time: 2020-04-24 Views: 44 Customized need to know: Magnet material is hard and brittle, processing performance is poor, general size and shape before leaving the factory, generally include: disc, cylinder, cuboid, ring, arc For shaped tiles and other special shapes, please provide the following information for special order production: 1. Magnet material and performance. 2. Dimensions and tolerances. 3. Order quantity. 4. Whether to magnetize, and the direction of magnetization. 5. The maximum temperature of the magnet working environment. 6. Surface treatment requirements. If NdFeB is galvanized or nickel-plated. 7. If there are other special requirements, please specify. [Purchase Instructions]: 1. Since the magnetic field will interfere with the relevant control equipment and computers on the plane, the company's products generally cannot be transported by air, but can only be transported by land express, train and road freight. So please pay attention to whether there is express delivery in this area when you buy. Since the magnets can only be shipped by land, we will not accept the middle or negative reviews due to slow express delivery and other reasons! 2. The magnet is a fragile product. When the magnet is attracted or separated from other components, be very careful not to impact, otherwise the magnet may break or pinch your hands. The owner is not responsible for it! When the magnet cannot be separated, it is recommended to push it horizontally and stagger it. 3. Please carefully check whether the product is damaged before signing for receipt. If there is a problem with the product, please refuse to sign! Individual couriers do not allow first inspection and then sign for receipt, then you must first sign for receipt but be sure to check and accept with the presence of the courier. If there is a problem, let him return it and issue a proof of the problem with the goods. If you ask a colleague or friend to sign it, please also inform If the problem is found on the spot, let the express return it, so you don’t have to pay for the freight. If the problem is discovered after signing for the receipt, the freight will be paid by you! 4. The object may have an impact on some measuring equipment such as electricity meters, gas meters, etc., making the measurement inaccurate. We hereby inform that our store is not responsible for all legal consequences caused by misuse or illegal use of this item! 5. Due to the large number of specifications, some pictures are not taken in kind. Please use a ruler to mark the required size before taking the picture. There is an accurate description of the size in the baby details for reference. The medium and the product due to the difference between the goods picture and the product size are not accepted. Bad review. Magnet knowledge: Magnets are generally divided into two categories: hard magnetic and soft magnetic. The magnets we often refer to generally refer to hard magnets or permanent magnets, so the name implies, it is a magnet whose magnetism basically does not weaken over time under normal conditions. Permanent magnet magnets are divided into two categories: The first category: metal alloy magnets include neodymium iron boron magnets, samarium cobalt magnets, and alnico magnets. The second category: ferrite permanent magnet materials 1. Neodymium iron boron magnets: It is the magnet with the highest commercial performance currently found. It is called the Magneto King. It has extremely high magnetic performance and its maximum energy product, which is more than 10 times higher than that of ferrite. It has hard texture and stable performance, so its application is extremely wide. The often said strong magnet refers to the neodymium iron boron magnet, because its chemical activity is very strong, so its surface layer must be treated. (Such as Zn, Ni plating). 2. Ferrite magnet: It is made by ceramic technology. It has a relatively hard texture and is a brittle material. Because of its good stability, low price and moderate performance, ferrite magnet has become the most widely used permanent magnet. 3. Magnetic frames derived from neodymium iron boron magnets, ferrite magnets through special processing, rubber magnets and other products are widely used. Samarium-cobalt magnets and alnico magnets are used in special applications due to their high prices and special performance. occasion. Examples of NdFeB applications: Electroacoustic field: speakers, receivers, microphones, alarms, stage audio, car audio, etc. Electronic appliances: permanent magnet mechanism vacuum circuit breaker, magnetic holding relay, watt-hour meter, water meter, sound meter, reed switch, sensor, etc. Motor field: VCM, CDDVD-ROM, generators, motors, servo motors, micro motors, motors, etc. Mechanical equipment: magnetic separation, magnetic separator, magnetic crane, magnetic machinery, etc. Medical and health care: nuclear magnetic resonance instrument, medical equipment, magnetic therapy health products, magnetized fuel economizer, etc. Other industries: magnetized anti-wax device, pipe descaler, magnetic fixture, automatic mahjong machine, magnetic locks, door and window magnetism, luggage magnetism, leather magnetism, toy magnetism, tool magnetism, craft gift packaging, etc. 1. Model: N33-N50 2. Size: Any variable size, customized according to customer requirements. (Anyvariablesize) 3. Electroplating layer: (Electroplatedcoating): zinc (ZN), nickel copper nickel (NICUNI), nickel (NI), blue white zinc (Bluewhitezinc), colorful zinc (Coloredzinc). 4. Application scope: electronics, electrical appliances , Packaging, toys, gifts and crafts, fitness magnetron cars, motors, micro motors, computers, instruments, meters, motorcycles, cameras, mobile phones, clocks, audio, home appliances, office automation, magnetic therapy and various fields of daily life. 5. At present, the international advanced Parylene coating equipment, the domestic first-class electrophoresis production line and advanced electrical testing equipment provide a reliable guarantee for the quality of the product. 6. Instructions for use The product has strong magnetism and should be pushed away with the hand plane. 7. Caution: This product has high strength magnetism. Keep children away from playing, and it is strictly forbidden to swallow. The product material is brittle and it is strictly forbidden to collide with each other. Magnets are soft and hard.
