A German automotive client required magnets for drive motors of mass-produced vehicles, and had long struggled with magnetic attenuation under high temperatures and insufficient dimensional accuracy. Saint Langma customized sintered NdFeB arc-shaped magnets for this project. The minimum thickness reaches 0.3 mm with dimensional tolerance controlled within ±0.02 mm. Equipped with multi-layer anti-corrosion coatings, the magnets can withstand temperature fluctuations ranging from -40℃ to 150℃.

The optimized magnets effectively boost motor power output and cut energy consumption. We supervise every production procedure and conduct magnetic property tests on each batch to ensure consistent quality. Mass stable supply has been achieved. The solution helps the client upgrade its powertrain and is reliably adopted in multiple new energy vehicle models.

A South Korean manufacturer of lithium battery cathode and anode materials encountered production difficulties. Micro ferrous impurities mixed within powder raw materials can easily scratch electrode sheets, trigger internal micro-short circuits, and reduce battery cycle life. Conventional iron removal equipment has dead zones for material accumulation and carries risks of metal debris shedding that contaminates powder, failing to satisfy high-purity production requirements for lithium batteries. 

Saintlangma custom-manufactures high-strength magnetic bars for clients. Built with NdFeB magnetic cores and encased in seamless 316L stainless steel sleeves, these magnetic bars achieve a surface magnetic flux density of 13,000 Gauss. The bars efficiently capture fine ferrous contaminants. Featuring a smooth, dead-space-free structural design, they trap micron-scale ferrous impurities with high efficiency. Having passed multiple rounds of cleanliness testing and long-term corrosion trials, the magnetic bars are now in mass production. They significantly improve the purity of cathode and anode powders and stabilize the quality of battery cells.

A humanoid robot developer faced bottlenecks during the development of joint motors. Robot joints feature limited installation space, which requires compact and lightweight magnets. Ordinary magnetic rings have excessive wall thickness and uneven magnetic field distribution, resulting in insufficient motor torque and operational jitter, failing to meet the requirements for flexible robot movement.

Saint Langma delivered customized high-grade magnets manufactured by an integral forming process to create an ultra-thin ring structure, perfectly fitting the confined joint space. These radially magnetized rings deliver uniform and stable magnetic fields, effectively reducing motor cogging torque and improving control precision. Strict dimensional tolerance control and reliable surface coating enable the products to withstand vibration and impact from continuous reciprocating rotation. 

After multiple rounds of sample optimization and long-term working condition tests, the magnets are now supplied in batches, enabling smooth and responsive motion output for robot joints.

A Danish edible oil manufacturer encountered technical challenges. Micro-scale ferrous impurities were generated during raw material processing and oil refining. These tiny iron particles catalyze oil oxidation, darkening the oil color and shortening its shelf life. Conventional iron removal solutions risk altering the physical and chemical indicators of oil, failing to meet food production standards. 

Saint Langma customized food-grade magnetic bars for the client. The bars adopt NdFeB magnetic cores encased in seamless 316L stainless steel sleeves, delivering a surface magnetic flux density of 10,000Gs. The magnetic bars efficiently capture micro iron contaminants. With a smooth, dead-space-free structure, they avoid shedding metal debris that would contaminate the oil. All products are inspected before delivery in compliance with food industry specifications. After deployment, the system effectively slows oil oxidation and discoloration, stabilizes oil quality and extends the shelf life of finished products.
