Remark: The products and pictures showed above are only to present the scope of our manufacturing types. We're happy to evaluate if we could custom the parts according to your drawings or samples after receiving them.

The brake disc (or rotor) is the rotating part of a wheel's disc brake assembly, against which the brake pads are applied. The material is typically gray iron,a form of cast iron. The design of the discs varies somewhat. Some are simply solid, but others are hollowed out with fins or vanes joining together the disc's two contact surfaces (usually included as part of a casting process). The weight and power of the vehicle determines the need for ventilated discs.The "ventilated" disc design helps to dissipate the generated heat and is commonly used on the more-heavily loaded front discs. Our advantage as below: 1.-Professional Manufacture ,high-volume environmental foundry electric stoves and foundry production line,output reach 5000 tons per month. 2.-Long Service Life and quality warrantee period & Low noise for brake discs. 3.strictly testing and ways for discs and drums dynamic balance.keep the products stable balance during driving. 100% test brake discs' crucial dimension inspection and machining surface. 4.Material: casting Iron 5.Standard: HT-250 raw material G3000 standards. 6.Solid or vented for brake discs style: VENTED 7.Packing: Neutral or Color carton.poly woodpallet. 8.Short-term Export Credit Insurance, TS16949 and ISO 9002certificate; 9.many years of export experiance.familiar to many kinds of certifications and government CIQ regulation.many kinds of goverments and Customs documents meantime.FAQQ1: Are you a trading company or a factory?
