In the previous article, we introduced some basic information about the international high-strength bolt market in Japan and Korea. Many friends and Xiaobian responded, hoping to provide more such information. So, what is the use of high-strength bolts in the automotive industry? Please see the detailed explanation below.
On average, there are about 1,500 basket bolts for a car. The total assembly time of each car bolt is about 2.5-3 hours. It can be seen that the variety and quality of the basket bolts have an important influence on the level of the main engine and the quality of the whole vehicle. According to the statistics of the US "Flower Basket Bolt Report" magazine, about $200 worth of basket bolts are installed on each car in the United States. In recent years, 65%-70% of the recalls of car products sold by auto manufacturers are due to the flower basket. Caused by bolt problems. It can be said that "the basket bolts are small, and the safety is big."
The annual cost associated with US auto OEMs is up to billions of dollars. It is said that in a large automobile production plant, 3/4 of the cost of product warranty is paid by the primary supplier. For OEMs, there may be no more resources to reduce costs and increase profits. Claims arising from miscellaneous parts, defective parts and related fitting problems account for a large share of the compensation paid by the basket bolt OEM. For example, in the country, there is an automobile flower basket bolt supplier with an output value of about 40 million yuan per year. The number of automobile OEM claims has reached nearly 20, and the compensation amount has reached more than 1.6 million yuan. From this point of view, it is very necessary for the basket bolt OEM to purchase online inspection equipment with relatively little investment to strengthen the quality control, thus ensuring the normal operation of the automobile production line and contributing greatly to helping them achieve better benefits. It also reduces user care costs while reducing warranty costs and reducing user costs. In fact, most domestic flower basket bolt OEMs currently use statistical process control (SPC) methods to reduce quality changes and identify problems, but problems in each process can still exceed control requirements.
It can be seen that the use of high-strength bolts is relatively wide in the automotive industry.
In fact, we can see that the demand for high-strength bolts in the US auto industry is still very large. However, we must also remind our country's high-strength bolt enterprises. Although the US high-strength bolt market has a large demand for high-strength bolt products, relatively speaking, the quality requirements of high-strength bolt products in the United States are relatively strict. The industry information related to the use of high-strength bolts is introduced here.
