/PRCWT/Beijing, October 07, 2023 - In daily consumption, quality is often a key factor in determining brand reputation and consumer trust, and this is especially true for automobile consumption. As a consumer product closely related to the safety of people's travel, and the unit price is higher, the quality of the car is the most considered factor when consumers buy a car, after all, a high safety factor, durable and resistant car, in order to allow consumers to rest assured that their own and their family's travel life to it.
As the benchmark of Chinese automobile brand, GAC Trumpchi has already had a set of fine, efficient and perfect "GAC production mode", with high-precision automatic equipment guarantee, zero-defect production guarantee and whole-process control flow prevention system, to maximize for consumers to create a safe, assured and satisfactory quality car. Next, we will take you to understand the leading production process of GAC Trumpchi in the four links of "stamping, welding, painting and final assembly", and immerse yourself in the production process of a good quality car.
Stamping: Automatic stamping production line, 3D simulation technology, efficiency up to 12 pieces/min
The external structure of a car consists of five doors and a cover (4 doors + reserve door + cabin cover), top cover, left and right side walls, front and rear floors, etc. How do these parts come from? The answer is "stamping." The "stamping" process presses a high-strength steel plate into the parts of the body.
According to the lean production method and value stream concept, the stamping factory of GAC Trumpchi revolves around two automatic high-speed punching lines, adopts eight-link transmission press, advanced CNC hydraulic tension pad and linear seven-axis handling robot, and carries out orderly handling and palletizing by robots after the steel plate is pressed and passed the quality inspection.
It is worth mentioning that GAC Trumpchi fully applies 3D simulation technology in the production line and abrasive design, and the production beat is as fast as 12 pieces/minute, which is at the advanced level of the industry.
The application of 3D simulation technology is the biggest highlight of the stamping process, by verifying the equipment specifications and optimization parameters in advance, the production beat is simulated in the abrasive design stage, which can not only reduce the online debugging time, quickly plan and mold analysis of the new car mold process, improve the design efficiency, but also ensure the product shape and material formability, and fully protect the quality of the body.
Welding: 215 robots, to achieve the mixed-flow production of 5 vehicles, "intelligent manufacturing" charm
When the body parts are pressed and formed, it comes to the welding process, and the stamping parts are spliced into a complete body. This link is the part with the highest degree of automation. The welding factory of GAC Trumpchi vividly reflects the charm of China's "intelligent manufacturing".
Gac Trumpchi welding plant adheres to the concept of SSC(Miniaturization, simplification, lightweight) to achieve on-demand distribution of parts, while the parts flowing between the lines are transported by air, which greatly improves the utilization rate of space. Secondly, GAC Trumpchi adopts NC-flexible positioning system, the model switching time is less than 1 minute, and the mixed-flow production of up to 5 models can be realized at the same time, and the flexibility and intelligence are at the advanced level of the industry.
Welding is mostly assembled by robots, Trumchi vehicle manufacturing welding plant has a total of 215 robots, welding automation rate as high as 64%. Automatic line using adaptive welding technology, through MES(manufacturing execution system) and RFID(radio frequency identification system) interconnection, to achieve the automatic identification of models, configurations, both to ensure quality and improve output.
Coating: The 14-stage voltage coating is uniform, and the NVH is static and stable from the source
After the body welding is completed, it is time to put on a beautiful coat for the car - painting. Painting not only has a beautiful role, but also plays a role in protecting the body, in life, we use a variety of steel products will be painted on the surface to prevent oxidation, the car as a longer service life of outdoor travel tools, more need reliable protection.
Before painting need to be washed, degreasing, phosphating and other steps to clean the surface of the body, so as to make the paint and steel better integration, after the completion of the pre-treatment, the body will enter the paint in the pool over again, under the action of positive and negative charges, the paint will be attached to the car to form electrophoretic paint, also known as primer, this layer is related to the rust of the body, is a very important process.
The pre-coating process, electrophoresis process and subsequent spraying process of GAC Trumpchi are fully automated, and 56 spraying robots work together to complete the spraying operation of a car in an average of 42 seconds. The painting process adopts advanced technologies such as double pendulum rod/high permeability electrophoretic line, automatic robot spray painting and recycling of circulating air, which can improve the painting rate, high spraying quality and reduce the production cost.
In addition, GAC Trumpchi also has the industry's rare zoned anode 14-section voltage control, which can ensure the uniform distribution of paint thickness in each part of the body; The top coating uses the industry's most advanced B1B2 water-based no-medium coating process, while meeting low VOC emissions and high quality body finish. The sound insulation material related to the vehicle NVH - sound insulation damping pad is also completed by automatic spraying process, which guarantees the noise reduction and shock reduction of the vehicle from the production source.
Final assembly: The use of modern advanced level of process equipment, plus multiple insurance for quality
Then, it comes to the last step, which is also the most critical final assembly production link.
The assembly workshop of GAC PQI adopts a six-fold layout, which is divided into five functional areas: electric installation, internal installation, chassis, external assembly and composite. There are 139 effective working stations, which can realize the common production of 4-8 models. Through the use of modern advanced level of process equipment, a flexible factory with the shortest conveying distance and modular layout is built.
It has the windshield automatic installation, tire intelligent installation, camber detection technology and other bright technology, to the vehicle quality on the multiple insurance.
The glass is automatically loaded by the AGV intelligent handling robot, and the ABB robot takes parts, applies glue, detects the glue type in real time and automatically installs it. The image recognition and positioning system is used in the installation process, and the repeated positioning accuracy is as high as 0.12mm. In the tire, a key assembly point involving driving safety, GAC Trumpchi realizes tire pre-tightening, forward turning, reverse torque input, Angle control, etc. in less than 10 seconds and more than 20 steps, which greatly increases the safety factor of users' driving.
It can be seen that the birth of a car requires very complicated processes and high-tech equipment. The flexible, automated and intelligent production mode created by GAC Trumpchi will finish the "four processes" with high quality and efficiency, and continuously deliver products with good product quality and safety performance to the market.
In this regard, the warranty rate can be seen in the whole picture, "China Automobile warranty rate Research Report in August 2023" shows that GAC Trumpchi has won the independent brand champion with a three-year warranty rate of 64.9%; In the previous first half of the value rate list, Trumpchi M8, Trumpchi GS8, Trumpchi Shadow Leopard, Trumpchi GS4 PLUS and other models were ranked No.1 in the subdivision list, fully verifying the quality and market recognition of Trumpchi cars.
The eyes of consumers are sharp, GAC Trumpchi ranked first in J.D. Power China New car quality Chinese brand for 8 consecutive years, achieving a two-way relationship with consumers. In the future, GAC Trumpchi will continue to deepen the strength of "made in China" and become a trustworthy auto brand that consumers are willing to choose.
