Open Pandora's box and explore different SAIC Volkswagen.

As the first joint venture to enter China, it has been rooted in Anting for 37 years. From 1983, the first Santana car of Shanghai Volkswagen rolled off the assembly line to SAIC Volkswagen now, and in the process of catching up with many rising stars, it has always maintained the leading position in China automobile industry. Quality is the life of SAIC Volkswagen, which may be the best answer to why SAIC Volkswagen can lead the domestic passenger car market all the year round.

How does SAIC Volkswagen infiltrate quality culture into the blood of enterprises? A few days ago, the author walked into the quality assurance center located in the first factory of SAIC Volkswagen Anting, focusing on visiting the quality assurance laboratory, and personally felt the "most authentic" quality assurance system of SAIC Volkswagen.

Test whether you are sensitive to color with Munsell color chess.

SAIC Volkswagen has strict requirements for every interior and some exterior decorations with color definitions. Since the establishment of SAIC Volkswagen Color Difference Group in 2003, the core of the work is to ensure the appearance matching of the interior parts of each Volkswagen product car. SAIC Volkswagen has its own color difference standard VW50 190, which is one of the most stringent standards at home and abroad. The supplier needs to send the finished parts to the quality assurance laboratory, and can only install them on the finished vehicle after being approved by the color difference engineer. The color difference team will conduct random inspection every week. If unqualified parts are found, the supplier will be informed to rectify and send samples again until they are qualified. Those that are seriously unqualified shall be scrapped.

The requirements of color difference group on the appearance of parts include color, luster and surface quality. The evaluation method is visual inspection combined with measured data, but at present, most automobile enterprises only require visual inspection matching. Visual matching is to evaluate the matching state of a real car from the consumer's point of view; The measured data can correct the influence of subjective factors of engineers. It is said that if you want to become a color difference engineer of SAIC Volkswagen, you must first pass the Munsell color chess test and be sensitive to color. The author made a simple 24-color test of Munsell color chess on the spot, and arranged 24 disturbed same-tone color chess according to the gradient of depth. The first attempt turned out well, except for one mistake.

In terms of hardware, the color difference team of SAIC Volkswagen assisted the appearance evaluation with a variety of professional equipment, including the light source room of the whole vehicle, the small light source room, and the dermatoglyphic tester imported from Germany. There are also small light source rooms, standard light source boxes, color difference meters, glossmeter, etc.

Among them, Uwe? Braun? The vehicle-mounted light source room can switch multiple light sources at any time, ensuring the consistent visual matching of vehicles under F 1 1, D65 and other light sources, and it is in a leading position in China.

The air quality inside the car is also a part that cannot be ignored.

In recent years, there are always several brands named at the 3 15 party because of the air quality inside the car, and air quality has become an unavoidable topic among car companies.

According to the VW50 180 standard, the smell and distribution team of SAIC Volkswagen ensures that the whole vehicle meets the national standard GB/T? Requirements of 27630 on the limit of eight toxic and harmful substances of "pentatriphenylaldehyde". At the same time, all interior assemblies are required to meet the EU CLP regulations at the initial stage of development, and the EU CLP regulations strictly stipulate the limit value of about 1400 kinds of toxic and harmful substances.

SAIC Volkswagen has been committed to building a green cabin. Starting from 20 18, SAIC Volkswagen tried to replace solvent-based glue with buckles or welding on interior parts during the development of new projects.

Key interior parts such as seat cover, roof and steering wheel in the car must be baked in the "in-car sauna room" to remove toxic odor before they can be put on the line.

SAIC Volkswagen has also made special efforts to solve the technical problems of TVOC. TVOC refers to the total concentration of volatile organic compounds between C6 and C6 -C 16, including most toxic and harmful substances and odor substances. TVOC concentration of vehicles is the most comprehensive index to evaluate whether vehicles are green or not. Therefore, SAIC Volkswagen has formulated a TVOC limit standard for interior trim which is higher than that of German Volkswagen, which is the first vehicle material standard of German Volkswagen in China.

In addition, in terms of odor emission improvement, SAIC Volkswagen introduced GC-O (odor traceability) equipment, and finally developed an "electronic nose" with sensitivity matching with human nose through the accumulation of odor substances in parts and raw materials combined with neural network algorithm.

Come on, let's make a part CT.

It's the first time I heard of doing CT for auto parts. In fact, it's the same as people with chest pain and leg pain who need to go to the hospital to take a photo to check the internal situation. However, this is carried out before the vehicle assembly, and it is mainly used for nondestructive testing of parts defects and structures to prevent product defects from causing functional failure and affecting driving safety.

As early as 2008, SAIC Volkswagen purchased industrial CT equipment at a high price of 6.5438+million yuan, and it was also the first automobile factory in China to adopt industrial CT equipment for quality control. This equipment plays an important role in early identification of parts quality, safety of function development, batch quality control and failure analysis.

A small screw is related to the quality of a car.

Each car consists of more than 10,000 parts, which are mainly connected by welding and bolts. Among them, there are about 2000 fasteners such as bolts and nuts, and 80% of the work stations in the assembly workshop are screwing "screws". The quality of fasteners and the level of tightening technology play a vital role in the strength of the whole vehicle and the firmness of the chassis.

In addition to ensuring the stability of the quality of high-strength fasteners through strict testing, SAIC Volkswagen is also committed to researching the three leading tightening technologies in the industry, testing more than 15 sets of parts for each important tightening point, and then calculating the most reasonable tightening process according to curves and data to ensure that each screw is fully tightened on the vehicle, thus providing a basic guarantee for chassis safety and vehicle comfort.

In addition, the tightening of all workshops of SAIC Volkswagen adopts multi-level torque monitoring, and all tightening curves and data are collected and saved by the tightening system, so that all tightening data can be recorded and traced.

An indispensable "internal stress" detection

"Internal stress" is a new word that appears in front of the author. As a physics kid, it's hard to understand after listening to it twice. Internal stress is an important index of metal parts. It is invisible and intangible, but it does exist inside the part, which affects the strength of the part. Internal stress can be divided into two categories: one is compressive stress, which is helpful to improve the wear resistance and fatigue strength of parts; One is tensile stress, which will reduce the strength of parts and easily lead to early failure of parts. Simply put, it's like everyone is under pressure. Some people have good resistance to pressure, they will bite their teeth and stick to it, while others will collapse if they have poor resistance to pressure.

In 20 13, SAIC-VolkswaGEn took the lead in introducing the XRD3003 internal stress meter produced by ge company, which mainly detects the internal stress of metal parts such as engine, gearbox and chassis. At the same time, it can measure the internal stress value and stress distribution of the parts, guide the production of suppliers, and ensure that the parts meet the design requirements and will not fail during use.

Visiting the entire quality assurance laboratory of SAIC Volkswagen not only subverts the imagination but also makes sense. There has always been a popular joke in the automobile circle: "Nissan studies leather seats, Honda studies engines, and Volkswagen studies China people". Although it is a joke and a little ironic, there is no denying that the public has made great efforts to study the psychology of consumers in China! However, the product quality is unambiguous, which inherits the rigor of German industry and even exceeds the standards of the German public.

Building a car is never a simple assembly on the production line, but the reverence of the car maker for this profession and the awe of life. SAIC Volkswagen pursues the best product quality, understands the needs of users and creates greater value for users. Otherwise, it will not gain a foothold in the China market for more than 30 years. It's really a pity to see that Beijing Jeep and Guangzhou Peugeot, which entered the China market at the same time, didn't even leave their own company brands.
