The drum brake is a brake in which the brake shoe tightly presses the brake lining against the inside of the brake drum through a brake transmission mechanism to generate braking force, decelerate the wheels or stop the vehicle within the minimized distance as necessary, so as to ensure driving safety and reliable parking without slipping.
We have world-leading automatic casting equipment. By being produced with the vertical flaskless molding technology, various accessories of drum brakes have stable dimensions, small deformation, good hardness consistency, and good processing property, thus guaranteeing the drum brake quality.
The major accessories include adjusting arms, brake back plates and brake shoes which are made of QT450-10, QT500-7, QT600-3 and QT400-12. They are applied in the braking systems of heavy trucks and buses. The drum brake is broadly applied in the braking systems of trucks and trailers.
We use advanced numerical control lathes and processing centers, as well as internationally advanced detection equipment including ARL photoelectric direct reading spectrometer from Switzerland, Zeiss metallographic microscope from Germany, carbon-silicon analyzer imported from Japan and Hexagon three-coordinate measuring instrument in processing drum brakes, to provide more stable and reliable product quality.
