In recent years, China's automobile industry has developed rapidly. In particular, in the past 2009, the annual sales of the auto market exceeded the 13 million mark, officially surpassing the United States and becoming the world's largest auto market. Accompanying this is the vigorous development of the auto parts industry. In order to compete for the market share in China, major auto manufacturers have strengthened their cost control capabilities in the Chinese market, and parts and components support systems will be gradually liberalized. Parts procurement will slowly tilt toward China. With the rising of auto parts industry, the chances of auto manufacturers experiencing problems in parts procurement and inspection should be reduced.

In the research and development stage, the various functions and parameters of the car have been basically determined, but the greatest impact on the quality of the car than the drawings into a manufacturing process. The so-called accumulation of soil will affect the whole, and the quality of each component will directly affect the performance of the vehicle. Therefore, the procurement and inspection of parts become an extremely important part of the automobile manufacturing process.

Purchasing parts and components to the direction of specialization and specialization

The structural characteristics of China's auto parts industry is mainly due to the scattered and backward manufacturers. The entire vehicle manufacturer tends to purchase on-site or purchase from the company's internal companies, and implements multiple procurement methods for the same parts of the same model to promote competition among parts manufacturers. In this way, because the production scale of each component factory is too small, it will not be sufficient to realize economies of scale, thus increasing costs, and too small a production scale will result in the inability to invest sufficient funds for R&D. The entire vehicle manufacturer has implemented multiple orders, so that the parts factory can not expect to obtain stable orders, it can not be fully invested, and thus it is difficult to improve product quality.

Fortunately, due to the huge increase in the status of the Chinese market in the global automobile market, many foreign automakers have begun to consider the gradual release of the parts and components supporting system, and cooperate with local Chinese parts manufacturers to establish long-term strategic partnerships. relationship. In terms of specific operations, it is possible to start with the control of parts and components companies, select parts of well-known brands that are widely recognized by customers, and dynamically adjust the list of parts procurement companies each year to win the fittest according to the use situation of the previous year; , Establish quality files of parts and components, carry out routine analysis on a monthly basis, and supervise and promptly rectify the defective parts and components companies.

In addition, compared with European and American automakers and Japanese automakers whose domestic auto companies are relatively mature, local auto makers have high procurement costs and complicated procurement procedures. In order to pass on cost pressures, it is likely that they will be able to suppress supplier costs. This will inevitably lead to The supplier of parts and components will accordingly achieve the goal of reducing costs by reducing product quality within a certain range. Therefore, continuing to develop the procurement process and system in a professional and scientific direction is one of the important ways to ensure the quality of parts and components.

Inspection of parts and components to scientific and institutionalized development

With reliable parts supply, the next inspection process is also indispensable. Quality inspection is the most important thing to ensure the reliability of the product. Components from the supplier to the assembly shop are only checked in layers in the middle to ensure that the quality of the vehicle is not affected. Only from the operator level to control the occurrence of defects can ensure the reliability of the final product.

For the inspection of parts and components, a scientific sampling inspection system should be established to eliminate the hidden dangers of quality. Specific operations can be spotted according to small parts, and 100% inspection is required before large parts are put into storage. Establish records for parts and components of various specifications, trace back the raw materials for each part, and provide records for specifications, models, and other indicators. If a parts and components company needs to replace raw materials halfway, it should be re-inspected, examined, and registered.

Different incentives and penalties are applied to different suppliers to promote suppliers' efforts to increase product quality control. In accordance with certain standards, all parts and details are standardized, and standardization is the process of formulating, implementing, and constantly improving standards, which is the process of continuously improving quality and improving management.
