China Neodymium And Ferrite Magnets Manufacturer & Supplier 
Plastic bonded neodymium magnet is a kind of composite material made of neodymium magnetic powder mixed with plastic binder and manufactured through a specific molding process, about this type of magnet, I sorted out some customers often ask a few questions.

Q1. Is the plastic bonded neodymium magnet strong?
Plastic bonded neodymium magnets do not have the same magnetic properties as sintered neodymium magnets, but they are still one of the high-performance magnetic materials. They are particularly suitable for application scenarios that require high magnetic flux density, miniaturization and lightweight design. The exact value of the magnetic properties depends on factors such as the quality of the magnetic powder and the proportion of the binder.
Q2. What kind of shapes can plastic bonded neodymium magnets be made into?
One of the advantages of plastic bonded neodymium magnets is that they can be injection molded into almost any shape, including but not limited to cylindrical shapes, ring shapes, and special complex shapes.
Q3. Are these magnets heat resistant?
The temperature resistance of plastic bonded neodymium magnets depends on the powder used and the plastic substrate material. Generally speaking, the operating temperature range of these magnets can be from -40°C to +150°C.
Q4. Do plastic bonded neodymium magnets corrode easily?
Plastic bonded neodymium magnets usually have good corrosion resistance, especially when plastics with good chemical stability are used as the binder. Common binder materials include nylon, polyester, epoxy resin, etc. These materials themselves have certain moisture, water and chemical resistance.
Q5. Do plastic bonded neodymium magnets require additional surface treatment?
Plastic bonded neodymium magnets usually do not require additional surface treatment because the plastic substrate itself has a certain level of corrosion resistance.
Q6. How does the magnetic properties of plastic bonded neodymium magnets compare to sintered neodymium magnets?
Plastic bonded neodymium magnets are generally less magnetic than sintered neodymium magnets. Since plastic bonded neodymium magnets are mixed into the plastic substrate during production, the magnetic properties will be reduced. In general, their magnetic energy product will be 30%-50% lower than that of sintered neodymium magnets. However, in applications where very high magnetic properties are not required, their performance is fully satisfactory.
Q7. How much do the plastic bonded neodymium magnets cost?
Prices are affected by a variety of factors, including raw material cost, complexity of production process, order quantity, and market supply and demand conditions. Generally speaking, you can get a more favorable price by ordering in bulk. If you have specific purchasing requirements, you can contact us for the latest quotation information.
