Material Selection and Casting of Brake Drum
Each brake drum begins with high-grade cast iron, chosen for its natural ability to absorb and dissipate heat during braking. Our foundry process ensures that the microstructure of the iron is uniform, reducing the risk of cracking under thermal stress. Following casting, each drum undergoes a thorough inspection to verify dimensional accuracy and material integrity.
Machining and Surface Finish
After casting, brake drums are drilled, turned, and finish-ground on CNC equipment, maintaining tolerances within tight limits. This precision machining guarantees consistent contact between the drum and brake shoes, which is essential for predictable braking performance and even shoe wear. A smooth, fine surface finish also helps to minimize noise and vibration during braking cycles.
Quality Control and Testing
Xingtai SNT Auto Parts Factory implements a multi-stage quality assurance program. Incoming raw materials are tested for chemical composition and hardness. During production, we use automated measurement systems to monitor geometric parameters such as runout, concentricity, and thickness. Finally, each finished drum is subjected to non-destructive testing methods, including magnetic particle inspection, to detect any subsurface defects.
Performance Characteristics
Heat Management: Our brake drums are designed to handle the heat generated during prolonged or heavy braking, reducing the likelihood of brake fade.
Consistency: Tight manufacturing tolerances help maintain uniform braking force across all drums in a vehicle.
Durability: With an emphasis on structural integrity, our drums resist deformation and extend service intervals.
Compatibility: Engineered to fit Volvo OEM specifications, they mount easily and align correctly without additional modifications.
Application Spectrum
Suitable for a broad range of Volvo models—including heavy-duty trucks, construction vehicles, and city buses—our brake drums support both fleet operators and individual vehicle owners. Their reliable performance under varied road and load conditions contributes to safer operation and reduced maintenance costs over time.
