The structural design of fan-shaped reinforcing rib on the surface of brake drum ensures that the air flow can be stirred more quickly when the axle rotates, so as to enhance the heat dissipation and prevent high temperature burst.
The reinforcing rib can enhance the strength and wear resistance of the brake drum and prevent expansion and cracking.
It adopts high compactness molding machine and sand mold regeneration technology to realize dust-free casting, PLC automatic control, high precision, high density and outstanding anti-wear performance.
