In many car assembly and car repair processes, fasteners such as basket bolts are required. However, many people find that they encounter many problems when installing and using the basket bolts. Is the quality of the basket bolts unqualified? Today we will introduce the use of basket bolts in the automotive industry.
Although we have already controlled the key production processes, we still cannot guarantee 100% production of good workpieces. The level of unqualified defects cannot be reduced. Therefore, 100% final inspection or sorting must be carried out to meet customer requirements. The survey found that domestic car basket bolt OEMs used manual sorting, vortex sorting, optical sensing size and contour sorting after surface treatment. The sorting process is mainly to pick out bad products with obvious defects, such as quenching cracks, surface decarburization, dimensional deformation and so on.
For the domestic automobile basket bolts, the process detection and on-line sorting ability of important parts, especially high-strength thread basket bolts, are strengthened, and some human interference factors are eliminated, which has a great effect on ensuring the quality of supply.
Although the statistical process control (SPC) method has inherent defects in reducing the rate of failure, its role in production process control is still irreplaceable. It is the necessary control means to identify problems in the production process in order to correct them in time. The measurement information of the basket bolt size measurement data, material defects, heat treatment and surface coating can be more accurately determined by the 100% inspection data process of the quantitative inspection than the sampling inspection.
It is not difficult to find out that the smooth operation of the automobile assembly line, the safe driving of the vehicle and the good reputation of the manufacturer depend on the 100% defect-free basket bolt. In recent years, there have been a large influx of multinational companies' basket bolt companies, and the challenges and opportunities are not the same. Domestic local flower basket bolt enterprises create brands, improve quality, and ensure smaller defect rate of defects, from 1000-600PPM value to below 150PPM value, and constantly strive to achieve zero defect goal, which is the goal pursued by the basket bolt industry.
In the automotive industry, the use of basket bolts is still relatively wide. Those involved in related work should pay attention to the timely understanding of this information.
Through the above introduction, in fact, we can see that the emergence of the basket bolt problem has a part relationship with the production, because many flower basket bolt manufacturers can not guarantee the quality of each basket bolt product, only the same batch of basket bolts Sample testing is performed to ensure that most of the basket bolts are qualified. The knowledge about the use of basket bolts is covered in this article.
