Neodymium Permanent Magnets Manufacturer China Rare Earth Magnet Limited magnetic chucks are fixtures that widely used in processing fields, like machinery factories and molding factories, which can greatly improve clamping efficiency of steel materials. magnet chuck use rare earth … Neodymium Permanent Magnets Manufacturer China Rare Earth Magnet Limited Permanent magnetic chucks are magnetic fixtures that are widely used in processing fields, like machinery factories and molding factories, which can greatly improve clamping efficiency of magnetic steel materials. Permanent magnet chuck use rare earth neodymium magnet materials as cores and can change magnetic system of neodymium magnets inside of the chuck, which can attract and release artifacts that are processed, through flipping handles of suckers. In machining and mold manufacturing industries, clamping often used vices or pressing plates, which were time-consuming and inefficient. With appearance of high-performance neodymium magnetic materials, neodymium iron boron tends to be raw materials for developing magnetic fixtures. Therefore, permanent magnetic chucks emerge as required. Application Theory Based on principle of continuity of magnetic flux and principle of superposition of magnetic field, magnetic circuits of magnetic chucks are designed into several magnetic systems. Through relative motions of magnetic systems, strength of magnetic fields can added or canceled out, in which way attraction and releasing can be realized. Features 1. With high-performance neodymium permanent magnets materials as cores, sizes become smaller, lifting capacities stronger and magnetism is perpetual. 2. It can be used without electricity, saving troubles of electricity supply. 3. Optimized magnetic circuits make residual magnetism low to zero. 4. Professional designs enable appearance of the products to be better-looking. Related Design Before a permanent magnetic chuck is designed, the magnetic circuits should be well designed. A nice magnetic circuit enables more magnetic flux to concentrate on working surface, which meet the requirement of lifting capacity. Meanwhile, it can reduce usage of neodymium magnets materials. There are two magnetic circuits in a permanent magnet circuit, which can be classified into two parts---one is flexible and the other is fixed. In order to reduce magnetic resistance and increase magnetic flux on key working surface, it will adopt some flexible magnetic materials as magnetic yokes in permanent magnetic circuits. Maintenance 1. Before using the sucker, the surface should be cleaned in order not influence accuracy. 2. Working temperature should be -40°C to 50°C. 3. After being used, it should be rubbed with rust-resistant oil. China Rare Earth Magnet Limited customizes many types of magnetic assembly including neodymium magnet / smco / alnico / ferrite & steel parts / plastic parts / rubber parts, etc. View Details

Also, stock of Shenghe Resources, Guangsheng Non-ferrous and China Northern Rare Earth all go up over 5%, which are rated overweight by research institution. The most crucial driver of stock neodymium rare earth magnet is new energy cars. As is know to all, the government supports development of new energy cars with policies. In the future, new energy cars and hybrid electric vehicles will take place of conventional vehicles. Rare earth is the key material for manufacturing new energy cars and battery of hybrid electric vehicles. Permanent magnet motors of new energy cars are made of rare earth permanent magnets. Rare earth which is called “industrial monosodium glutamate” plays a critical role in future development of new energy cars. Neodymium magnets , with high energy product and coercive force, have the strongest magnetism which is as four times as that of common permanent magnetic materials. They are the best choice for small, light and thin electronic equipment. Motors of Prius HEV produced by Toyota are made of NdFeB magnets. Besides applications in new energy cars and hybrid electric vehicles, rare earth magnets are applied to wind power equipments, instruments, medical devices and intelligent robots. Currently, the government has wind power projects laid out, which stimulates market demand of permanent magnets. Therefore, permanent magnetic industry has a broad and promising prospect. Domestic rare earth magnetic materials have developed into the third generation. New materials are represented by sintered neodymium iron boron magnets. In a recent decade, growth of sintered NdFeB magnet in China has exceeded international level. The annual growth has reached 30%, but the global growth is only 20%. Besides predominant growth, sales of rare earth permanent magnetic materials cover 80% of the global market. Domestic rare earth permanent magnetic businesses have been over 200, among which China Rare Earth Magnet Limited, in the leading position, is the top manufacturer of rare earth permanent magnetic materials. Another 31 listed companies cover 60% of the market share. Comparing with foreign companies, local companies enjoy cost advantages of rare earth materials.

Function 2: magnetizing engine oil I believe that many people have once used Castrol oil, of which price is 300-400 Yuan. It protects the engine before it begins working. Before a car starts, its oil pump supplies engine oil upwardly. At the moment, engine oil cannot cover surface of parts, so the wear is high. But UMA magnetic molecules of magnetic protective oil can be absorbed on the surface of the engine like a permanent magnet, in which way it greatly reduces abrasion before a car starts. UMA means that before protection, additive in oil will be magnetized and produce a great deal of magnetic molecules. In this way, cylinders, pistons, connecting rods and valves have adhesion and attract other oil components to protect the engine. Also, adhesion and fluidity can be improved. Most additive of oil engine can be magnetized. Now we can use oil magnetized by strong neodymium magnetic field. Characteristics: 1. There are built-in rare metal—rubidium alloy magnetic steel. 2. It uses magnetic flux amplifier technology, of which the magnetic force is as 10 times as common magnets. It is the strongest magnet in the world. 3. It adopts focusing magnetic field technology. The magnetic distance is only 2cm and will not interfere with auto electric equipment. 4. It can endure temperature reaching 200°C. 5. It can be used repeatedly. Efficiency: 1. It can reduce engine abrasion by 30%. 2. It is able to prolong the service life by 30%. 3. It can lower increase of fuel consumption of aging engines. 4. It can reduce power decline due to aging engines. 5. It can decrease noise by 20%. Notice: Before buying MC filtration magnets, you should make sure that whether your car’s engine filter is metal or plastic. If it is made of plastic, MC filtration magnets are not applicable for it. Only metal can use the neodymium rare earth permanent magnets for it depends on magnetic force. Cautions: 1. There are strong magnetic steel in the magnetized device. 2. Do not put it close to objects of which temperature is over 200°C. 3. Do not disassemble the magnetic device, if you don’t change the oil filters. Installation Method: If you have any new idea or design, welcome to contact China Rare Earth Magnet Limited!

Automobile area will become the industry with the fastest increasing demand and the biggest consumer market of permanent motor magnets in America. Constant growth of cars and boom of hybrid energy vehicles will continuously bring up demand of motors. Motors are widely applied in automobile industry, mainly including neodymium magnet materials. Commonly, motors are used in anti-lock brake system, auto shift gear system, water and fuel pump, cooling fans and windscreen wipers. Currently, it is expected by another research institute, MarketsanMarkes that from 2013 to 2018, compound growth rate of demand of China rare earth permanent magnet materials will be 8.7%. According to Feedonia’s report, mechanical market will push the growth of motors. Under stimulation of lager construction cost, demand of high voltage alternating current (HVAC) motor will be increased. But American Market Research Company indicates that original equipment manufacturers (OEM) need more efficient motors with high values. Smaller and stronger motors will become the development direction for exploration of more efficient equipment. Meanwhile, they bring beneficial effect to more powerful rare earth permanent magnets materials. For example, limousines are inclined to using more small motors. However, Freedonia also warns that original equipment manufactures should increase pressure on manufacturers to guarantee price to be competitive. They also import inexpensive motors abroad. China is still the main manufacturer country of various kinds of motor, including neodymium magnets materials, which have stronger competitive power. Demand of alternating current motor (AC) will rise faster than that of direct current motors (DC) and covers a bigger market share. It is evaluated that in 2018 the sale volume can reach 9.6 billion US dollars. Rare earth permanent magnet material can be used in DC and AC motors. Lee Steinbock, an analyst from Freedonia, indicates that electric cars will occupy one third of the USD revenue of AC motors, which is mainly brought by hybrid energy vehicles. Demand of direct current motor expectedly will be 6.7 US dollars in 2018. These motors will be widely applied to transportation area. Manufacturers will be benefited from continuously increasing automobiles, air and aviation and other non-automobile transportation equipments. View Details

Recently, with government’s intensive regulation for rare earth, price of light rare earth has gradually become stable and price of heavy rare earth has a modest increase. The steady rise of price of raw materials benefits and improves middle manufacturers. Otherwise, financial charges will be produced. Due to strong cost transferable ability of neodymium magnets, cost pricing method can obtain more profit from a larger cake. From analysis of historical stock price, share price of NdFeB permanent magnets manufacturers will commonly jump sharply during the period of rare earth price’s rising. In Q3, 2014, performance of the four main listed companies recovers steadily. We judge that performance inflection point is expected to be reflected in 2015, with the rise of rare earth price and recovery of downstream demand. Recover in demand of industry of energy conservation and emission reduction, represented by air-conditioners, probably becomes a factor out of expectation in medium term. After going through a decline, neodymium has comparative advantages, comparing with ferrite. Also, air-conditioner industry possesses the price foundation to reuse NdFeB. In addition, with implementation of new energy and efficiency standard of variable frequency air-conditioners in 2013, neodymium iron boron permanent magnet becomes the essential condition of compressors in air-conditioners. In 2015, reuse of neodymium in variable frequency air conditioners will boost the demand, which possibly leads to a demand going beyond expectation. The rapid development of new energy cars will stimulate a long-term prosperity of neodymium industry. VCM market, the main downstream application of NdFeB, tends to be saturated. Therefore, core power of future long-term space comes from automobile market. New energy cars, in particular, will largely push the demand o neodymium. It is expected that in 2020 demanding quantity of NdFeB will exceed five tons, of which annual growth hopefully surpasses 60%. New energy cars will bring subversive influence on industry. Besides, under a 4.0 industrial generation, demand of high-end permanent magnets may encounter an explosive growth. A long-term golden period will usher in NdFeB industry. The two-eight industrial structure manifests strengthening competitive advantages of quality companies. From 2014, magnetic enterprises still continues downturn of last year. The gap between business become lager and there is a huge discrepancy between high-end and low-end products. 20% of enterprises can meet the demand of high-end products, but the rest 80% is closed or goes out of business. Strategies and Advice of Investment: With the reuse of magnetic material of air-conditioner compressor businesses, sales volume of magnetic material used in wind power and automobile industry increases sharply. Under the circumstance where price of rare earth steadily rises, high-end neodymium industry encounters a recovery period. China Rare Earth Magnet Limited is benefited from downstream demand, with its reasonable product layout, stays a step ahead in new energy cars, comparing with other manufacturers, which is a beneficiary in this industry. Occupying high percentage in wind power industry, China Rare Earth Magnet Limited has a determined growth, is also a growth-oriented manufacturer, specializing in producing bonded NdFeB magnets , hot-pressed SmCo permanent magnets in the world.
