1. Perforated wire can effectively shorten braking distance and enhance heat dissipation effect.
2. The brake drum is processed by a large CNC lathe, and the dynamic balance error does not exceed 0.5. Beautiful sand coating process.
3. The brake drum should have sufficient wall thickness, and a circumferential or axial reinforcing rib should be cast on the outer surface near the opening to improve strength. It can also play a heat dissipation role, reduce the temperature of the friction surface, shorten the brake cooling time, and increase the energy capacity by 35% to 40%.
4. The material is H250 gray cast iron, with good shock absorption effect, good heat resistance, and high temperature resistance. The surface of the brake drum is painted to reduce external wear.
