No. 12, A3, gucheng industrial park, longyao county, xingtai city, hebei province.Brake drum failure in the use of the process, mainly cracking and wear, but from the customer complaints and claims reflected data statistics, is mainly the former. That is to say, most of the failure of the brake drum is in the case of normal or even slight wear, that is, cracking and can not continue to use.
After failure analysis of the failed parts, it can be concluded that there are three main reasons for failure:
(1) The mechanical properties of the casting body are lower than normal requirements.
(2) There are casting defects in the casting, especially shrinkage at the flange rounded corners.
(3) the car overload is serious, brake frequently and spray water to cool in the braking process, and this kind of failure parts check their mechanical properties and metallography are in line with the product requirements.
The production process of brake drum is mainly focused on two aspects. One is how to ensure its mechanical properties and metallographic organization meet the requirements of the product. But how to reduce its casting defects. Especially internal defects in critical parts, in terms of reducing casting defects.
Brake manufacturers, Long Yao County Xiangyuan Co., Ltd. is a collection of scientific research, production, sales in one of the manufacturers, the company's main products are: brake drum, wheel hub, brake disc, brake shoes and other domestic and imported cars, semi-trailer, full trailer chassis accessories, complete varieties, stable and reliable quality. The company not only with sinotruk, Fuhua and other large oems, bridge factory to establish long-term stable supporting cooperation, and products exported to the Middle East, America, Europe, Africa, Southeast Asia countries and deeply customer trust.
