We have an annual production capacity of 20000 tons of sand castings and an annual production capacity of 5000 tons of loss model processing assembly line, mainly producing cast iron, steel, castings and machining of various products. It can produce a variety of automobile brake discs/rotors, as well as many automobile brake discs/rotors and brake drums. Hub and hub.

The design of the brake discs is somewhat different. Some are solid, but others are hollowed out by connecting the two contact surfaces of the valve disc with fins or blades (usually as part of the casting process). The weight and power of the vehicle determine the need for the ventilation panel. "Vented" brake discs are designed to help dissipate heat and are typically used on heavily loaded front brake discs.
