Okawa Machinery develops rare earth composite material mining car brake pads

In January 2013, Baotou Dachuan Machinery Technology Co., Ltd. used rare earth and ceramic as the main raw materials and adopted advanced high-temperature polymerization technology to successfully develop new types of products with stable friction coefficient, low wear rate, flexibility, low noise, and stable braking. Rare earth composite car brake pads for mining vehicles , this is the first time that such products have been developed in China.

Baotou Dachuan Machinery Technology Co., Ltd. is a founding enterprise of overseas students who have settled in Leicun Park, Inner Mongolia. Two entrepreneurs from China, returning from France, and four domestic Ph.Ds have formed an entrepreneurial team to make full use of the advantages of rare earth resources in Baotou to use rare earth composite materials for the first time. Developed mine car brake pads. The brake pad does not contain asbestos, the brake has no noise, high temperature resistance, good thermal decay performance, stable friction coefficient, excellent braking performance, good wear resistance, long service life, and fully meets the high load-carrying capacity of mine vehicles and braking High torque, frequent braking, and high heat generation.

The products were tested in loading operation by Shanxi Ruidebaoer Mine Engineering Co., Ltd. and Shanxi Qingkou Iron Mine. The friction coefficient and various performances are much higher than the current imported foreign products commonly used by mining vehicles. The mileage is used for other brake pads. More than doubled, the cost is more advantageous than other products. The successful development of this product will promote the research and development of non-asbestos friction materials in China, enter the world's advanced friction materials, form a domestic independent brand, and end the situation that China's mine car brake pads rely on imports. At present, this type of product has entered the small batch production stage.
