Product Brochure of Sidiwei Bimetal brake drum Market background: With Sitiwei bimetal brake drum, say no to the highway invisible killer! The brake drums in domestic heavy vehicles are widely made as traditional inblock cast drums. When the vehicle in overloading, high speed, especially in a long or steep slope, the braking force is large, and by continuous repeated brakes the temperature of the brake drum wall rises sharply, so the temperature difference between the inside and the outside wall is getting bigger, that the high temperature mechanical performance of brake drum material and brake performance will drop dramatically, which causes the longtitudial cracks in the inner drum wall into full of cracks. In that case the crack phenomenon is the reason of many accidents and is going to be a big potential and invisible killer on the way.（The common service life of traditional inblock cast drums are 1 to 2 months and no more than 3 months, so the after-sale demand is big .) Pic: Traditional inblock cast brake drum has a common problem of cracking or even directly off the top caused by internal longitudinal microcracks After years of research and development, the manufacture of high performance bimetal brake drum is the unique international technology we mastered in China, which adopted german top equipments and high-end equipments such as ten thousand tons pressure machine. It is a transformation and upgrading product of a brand new automobile brake drum, which effectively solved the widespread problems of traditional brake drums, such as poor heat dissipation, easy to crack, so the traffic safety is extremely improved. In consideration of the advantages it should have a very good market application prospect. It has even been tested that under the worst working condition the service life of the bimetal brake drum could still easily exceed 40,000 km(6 months) (It is an exclusive product inland at present which could not be faked in the short time)
