The brushless DC motors in industrial fans or exhaust motors adopt external rotor mode, which has greater torque than that of internal rotors. However, many external rotors are made of a sintered arc magnet, a magnetic pole using an arc magnet, which is inconvenient and inefficient. In addition, the external rotor has a very high requirement for dynamic balance, and it is difficult for a sintered arc magnet to achieve good dynamic balance. The injection molding magnetic ring can solve this problem very well because of high dimensional precision, which is very helpful for dynamic balancing. Moreover, it can be designed in various shapes or special structures for easy assembly. Bonded ferrite or rare earth magnetic compounds can be used as raw materials according to different motor performance requirements. Bonded magnet is effective for air circulation and heat dissipation.

Flowmeter induction rotor uses our ferrite/PA12 series products as raw materials. It is injection molded into the shape of a cross, which is suitable for mass production and can reduce the assembly cost by using the metal axis as an insert. Each blade is N or S pole, and the induction signal is obtained through the rotation of the blade in the process of water flow, so as to obtain the flow data. The flow rotor size varies, and the smallest can be less than 5mm3. The toughness and fluidity of the material are optimized so that very thin positions can be injected smoothly and are less likely to break. Flowmeter induction motors are widely used in various flow testing devices.

The application of high-speed motor in our daily life is more and more common, such as hairdryer, vacuum cleaner, ice breaker, and are also used in power tools. The speed of the high-speed motor is generally above 30,000 RPM, and the highest may exceed 100,000 RPM, which there is a risk of breaking when using sintered magnets and ordinary bonded magnets. We have done relative research on the demand for the high-speed motor. At present, we have the corresponding bonded ferrite and bonded rare earth compounds suitable for high-speed motor above 50,000 RPM. Similarly, we also have high mechanical properties materials for the magnetic ring of the high-speed motor.

These two products are innovative applications of injection molding magnets. One is a magnetic switch, which uses our high-performance ferrite/PA12 series products as raw materials. It is a combination of a magnetic sheet and stainless iron keys to replace a traditional spring or silicone button. The advantage of this button is that it is relatively light and thin, and will not fail because of the lack of elasticity after repeated use. In addition, multiple switches can be used to make the whole switch panel.
The other one is a buoy indicator, which, combined with a floating ball with a magnetic ring, can show the level of the liquid by flipping the discs. Different use environments have different requirements for mechanics and magnetic properties. We have developed high-performance ferrite/PA6 series products and ferrite/PPS series products with better solvent resistance. We focus on all kinds of innovative applications to make devices more convenient and experience better.
To meet the requirements of electric and intelligent vehicles, we focus on providing lightweight, low energy consumption, reliable and safe solutions. Our different kind of magnetic material can be used for motors, sensors, electromagnetic shielding, etc.

The cooling water pump in the automotive thermal management system: With the promotion use of electric vehicles, the requirements for automotive thermal management are becoming higher and higher. An electronic water pump or the oil pump is a critical component in the system. The rotor made of a bonded magnetic compound has huge advantages in a lightweight and quality controllability. At present, bonded magnetic compounds like ferrite/PPS and NdFeB/PPS are both applied to pump rotors. No matter inner or outer rotors, both can be made of the bonded magnetic compounds. The blade and the rotor can be made by injection molding as a whole. Or you can just make the rotor part by injection molding, the blade can be made of other materials by secondary injection. Because of the controllable dimension of the injection magnet, it has advantages in dynamic balance. Besides that, our compound can withstand the high and low-temperature impact of -40 degrees to 150 degrees without cracking or other problems.
We are committed to the targeted research and development of a bonded magnetic compound, combining mold design and injection molding process optimization, and contributing to energy conservation.

Sensor ring of automotive: From the initial vehicle speed sensor to intelligent driving, the application of a magnetic sensor ring is becoming more and more popular. At present, rubber magnet is used as raw materials for some magnetic sensors, but the mechanical properties of rubber make it unsuitable as an exposed component (it will be deformed easily by the impact from stone, and the performance will be an influence in high and low temperature). In addition, comparing to injection magnets, the magnetic properties of rubber magnets are lower ((BH) max≤1.4MGOe). And the longer sensing distance requires higher magnetic field strength of the surface. A bonded magnetic compound like ferrite with PA6 or PA12 binder can meet these requirements. The injection sensor ring that made by insert molding with the metal ring has the advantage of strength, toughness, and anti-collision, which enables the magnetic ring to be directly installed on the wheel hub. In addition, the surface magnetic field strength of the injection magnet is higher than the magnetic rubber, which enlarges the space between the induction probe and the magnetic ring.

The induction magnetic ring for the automobile is applied in automobile sunroof, wiper, seat, window, etc. It is divided into separate injection-molded magnetic rings and magnetic rings with metal inserts. Due to the excellent mechanical properties and dimensional consistency of the injection magnet, the magnetic ring can be directly assembled on the shaft of the motor without cracking or falling off in use. Comparing to ferrite/PA6, it is much more recommended to use ferrite/PA12. Ferrite/PA 12 series has a lower absorption rate, which makes better dimensional stability to meet different needs in different environments. The material we developed has better mechanical properties and processing fluidity, which is not easy to be achieved in sintered magnets or other magnets. Injection magnets offer a better solution for the lightweight and comfort of the automotive.

Automotive headlight steering motors: Because of the diversification of the structure design, an injection magnet provides a good solution for the production of a semi-arc rotor, reduces the amount of material without sacrificing other desirable traits, which is beneficial to the lightweight of the car. The recommended material is NdFeB /PPS series. It can be used at 200 degrees, which is applicable to the car lights. Our compound has greatly improved the problem of demagnetization at high temperatures. The good processing fluidity of the material also makes it easy to make small and special-shaped rotors by injection. At the same time, corrosion resistance of injection-molded NdFeB magnet is better than the ones that made by die pressing or sintering, as the plastic coating on the powder can avoid intergranular corrosion.
Aiming at the demand of energy-saving and intelligent home appliances, we are committed to improving solutions about man-machine interaction, noise reduction, and energy saving. Our products can be used in brushless DC motor, sensors.

As a typical application case of a bonded magnetic compound, a magnetic roller for the printer is the main component that carries toner in the printer. Comparing to the traditional sintered magnetic material, the magnetic roller made of bonded magnet can realize with multiple radial poles, like 4poles, 5poles, 6poles. Furthermore, the length to diameter ratio of the magnetic roller can reach to more than 30, which can not be realized in the sintered magnetic material. The magnetic roller made of the magnetic compound through injection molding or extrusion greatly improve production efficiency, and have the advantages of good dimensional consistency, uniform magnetic field distribution, and excellent mechanical properties. It achieves high-quality development effects for printers.

The rotor of electronic expansion valve in the thermal management system. The electronic expansion valve (EEV) controls the flow of refrigerant entering a direct expansion evaporator. It plays an important role to reduce energy consumption. With small size, multiple poles, high precision in dimension, EEV has the requirement of not cracking in high and low-temperature environments for a long time using in the refrigerant . The rotor that made of bonded ferrite/PPS or NdFeB/PPS will meet those requirements. Ferrite/PPS series ((BH) max = 1.6MGOe) is applied to the rotor with low power, and NdFeB/PPS series ((BH) max = 2-8MGOe) is recommended to use in the EEV rotor with high power. With the increasing demand for automotive thermal management systems, we are also constantly developing the magnetic compound with higher magnetic performance, higher cost-effective and lower demagnetization rates at high and low temperatures to meet the design requirements of the new generation of EEV rotors.
