The advantages of one-piece stamping body are mainly reflected in the following aspects:
Significant improvement in production efficiency: With the adoption of integrated stamping technology, the manufacturing time of the vehicle body has been significantly reduced from the traditional 1-2 hours to around 45 seconds, while the production cost has been reduced by about 40%.
Enhanced body strength and rigidity: Due to the reduction of welding points, the overall structure is more stable, with a torsional stiffness of up to 50000 N · m. The door rigidity is increased by 30%, with uniform force distribution and less susceptibility to cracking and rusting.
Outstanding weight reduction effect: For every 10 kilograms of weight reduction, the range of electric vehicles can be increased by about 2.5 kilometers, significantly improving energy efficiency and practicality.
Space optimization design: facilitates integration with the battery, expands the vertical space inside the vehicle, and enhances the overall functionality of the vehicle.
Durability and texture improvement: After the door and other components are stamped together, the structure is thicker and more reliable, and it is not easy to deform after long-term use
The one-piece stamping body and multi spot welding body are two different methods of body manufacturing, each with its own advantages and disadvantages:
Advantages of one-piece stamping body:
1. Simple process: Integrated stamping molding reduces complex processes such as welding and improves production efficiency.
2. High strength: The entire body structure is designed to be integrated, with uniform force distribution and overall high strength.
3. Good aesthetics: Due to the absence of welding points, the appearance is more aesthetically pleasing.
Disadvantages of one-piece stamping body:
1. High cost: Large stamping equipment and molds are required, resulting in high investment costs.
2. Difficulty in maintenance: Once damaged, it is difficult and costly to repair.
Advantages of multi spot welding body:
1. Low cost: The welding process is mature and the cost is relatively low.
2. Flexible manufacturing process: Different parts can be welded according to needs, with strong adaptability.
3. Welding firmness: Multi point welding can ensure the firmness of each welding point.
Disadvantages of multi spot welding for car bodies:
1. Multiple welding points: The appearance of the car body may have many welding points, which affects its aesthetics.
2. Quality control: It is necessary to ensure the quality of each welding point and have high requirements for process control.
In summary, both the one-piece stamping body and the multi spot welding body have their own advantages and disadvantages. The specific choice of method depends on factors such as vehicle design, production process, and cost control.
