Description :
Plastic-bonded magnets are particle composites with permanent-magnet powder embedded in a plastic binder. Hard ferrite (HF), various SmCo and NdFeB powders and, to a very little extent, AINiCo alloys are used as magnetic powder. For embedding the magnetic particles, thermoplastic binders as, for instance, polyamide (PA) or polyphenyl sulfide (PPS) and duroplasts like epoxy resins are used. Depending on the material composition and production process, isotropic and anisotropic magnets with differing magnetic and mechanical specifications are available. Since not only the type of magnet or plastic material, but the filling and alignment degree, too, determine the composite`s properties, the outcome is widely varying magnetic parameters and an outstanding variety in types and shapes.
We present Plastic Bonded Permanent Magnets that are quite effective as correction magnet in color picture tube and deflection yoke. Size Available: Customized
Neodymium magnets (also known as NdFeB, Neo or NIB magnets), are strong permanent magnets made from an alloy of neodymium, iron & boron. Part of the Rare-Earth magnet family, they have the highest magnetic properties of all permanent magnets. Due to their high magnetic strength and relatively low-cost, they are the preferred choice for many consumers, commercial, industrial and technical applications.NdFeB is divided into sintered NdFeB and bonded NdFeB. Bonded NdFeB is magnetic in all directions and corrosion resistance and is divided into Bonded Compression NdFeB Magnet and Bonded Injection NdFeB Magnet; while sintered NdFeB is easy to corrosion, the surface requires coating, generally divided into axial and radial magnetic charging. Advantages of Sintered NdFeB Magnet : 1. Very hard and brittle, high diamagnetic resistance, high cost / performance ratio, not suitable for high working temper ature; 2. Magnetic performance is higher than that of the rare earth cobalt permanent magnet, the residual magnetic induction strength, magnetic induction coercivity, the maximum magnetic energy product is very high, is the current magnetic performance of the best permanent magnet; 3. High cost performance.
Flexible magnets are low-cost extruded permanent magnets made by bonding a strontium magnetic powder ina flexible vinyl binder. Microcrystalline magnetic powder of flexible magnet leads to its high magneticperformance, and artificial rubber makes it very flexible. Its maximum magnetic energy product has reached 90KJ/ m3 (11.25MGOe), industrial mass production magnetic performance range of 16 to 68KJ/m3(2.0~8.5MGOe).Due to its excellent flexibility, it can assemble faster than molded magnets. Flexible magnetic sheets, magnetic strips and labeling magnets are easy to use and manipulate to your desired specifications. Advantages of Flexible Magnet: Flexible magnets are easy to use, easy to manipulate, low cost and extremely versatile. They can easily be cut, bent,twisted, slit, or coiled and adhere to multiple items and surfaces. In addition, flexible magnetic materials require no surface treatments so no special precautions need to be taken to protect the magnetic surface. Our simple sheet on Care Tips will ensure that the use of magnetic sheeting on vehicles will not mar paint finishes.

Bonded-NdFeB Magnet.
Injection magnet is a mixture of magnetic powder, resin, additive, which are injective produced by a specialized injection machine. The injection magnet power is lower than sintered magnet, but it has precise sizes, light-weighted, compact and various shapes.
Injection molded ferrite magnets Injection molded ferrite is another molding process of magnet category. Compared to injection molded ndfeb, the difference of injection molded ferrite lies in different magnetic powder utilized, therefore injection molded ferrite has lower magnetic properties due to ferrite features, but it costs much less than that of ndfeb. Features and benefits of injection molded ferrite L injection molded magnets can be of very complex shapes with high precision, typically, tolerance is+/- 0.005mm, it is suitable for high precision parts L it is a new technology to achieve adjustable magnetic properties, composite molding, elastic magnetization and high mechanical strength L by doing insert molding, magnetic material can be directly molded into or onto other assembly components without further assembly process L the material is harder to be cracked or chipped than sintered magnet
Product Description Compression bonded magnets are made by using many isotropic Neodymium, Iron, and Boron materials, as well as crushed & powdered Samarium and Cobalt ingredients. Combinations of different elemental grades are used to create specific magnetic properties. Compression bonded magnets offers higher magnetic strength than injection molded magnets due to their higher magnetic particle density, but is unfortunately limited to simple geometric shapes due to the compaction process. The epoxy used is very resistant to normal industrial solvent and automotive fluids.The normal applications of these magnets range from below -40 and beyond 165. Why choose Bonded NdFeB Magnet.? 1. High quantity and even volume manufacturing, with up to millions of pieces per year. 2. High accuracy in size. The bonded magnet may be formed into magnetic components of relatively complicated shapes. 3. Single-time molding and multi-poles orientation. 4. The injection molded magnet has a high mechanical strength and may be molded together with other matching parts. 5. Effective surface treatment to prevent corrosion. Good corrosion-resistance and nice surface: The product is coated with epoxy resin parylene-coating and the anti-corrosion is very good. The surface is smooth, clean and nice-looking. No bubble, no crack, no strip-off, and no chip. 6. Stable working temperature. The working temperature is high up to 150. 7. Excellent magnetic properties. The energy product is 3 times as large as anisotropic ferrite. The intrinsic coercive force is high. During the large-scale production, the magnetic properties are stable and the conformity is good. 8. Application to Bonded NdFeB. Widely applied in all kinds of mini-motors, auto motors, air-conditioner motors,automatic controlling devices, sensors,drivers,telecom and instrument industry.
