Application of Precision Sheet Metal Fabrication in the Automotive Industry

2025-07-31

Precision sheet metal fabrication is widely used in the automotive industry, encompassing areas such as body, chassis, and powertrain. Its core value lies in lightweighting, high precision, and process innovation:

1. Body Panel Manufacturing

Complex Surface Forming:

Drawing die technology is used to achieve deep drawing (up to 300mm) of components such as body sides and doors, with a material reduction rate of less than 15% and a forming qualification rate exceeding 99.6%.

Lightweight Material Application:

Aluminum alloys (such as 6016 and 6022 series) are replacing traditional steel sheets. Anodizing or ultra-mirror finishes (Ra ≤ 0.05μm) enhance corrosion resistance. Automakers such as Tesla have already achieved mass production of all-aluminum bodies.

High-Strength Steel Integration:

Second-generation aluminum-silicon-coated hot-formed steel (such as Usibor® 2000) boasts a strength of 2000MPa, reduces weight by 10%, and maintains toughness. It is widely used in key components such as battery housings in new energy vehicles.

2. Chassis and Structural Components

Integrated Molding Technology:

Tailor-welded blanks (TWB) and multi-directional stretching processes enable integral molding of chassis longitudinal beams, reducing weld points and improving structural strength.

Precision Tolerance Control:

Dimensional accuracy of key components reaches ±0.02mm, with CNC bending and laser cutting (±0.01mm accuracy) ensuring assembly consistency.

3D Printing Composite Process:

Topology optimization design combined with metal additive manufacturing reduces chassis component weight by over 20% while shortening R&D cycles by 50%.

3. Powertrain and Electrical Systems

Battery Housing Manufacturing:

A deep drawing process (depth ratio 2.5:1) is used to form the aluminum alloy battery housing, combined with laser welding to enhance sealing.

Heat Dissipation Component Processing:

Sheet metal stamping processes are used to produce the radiator's air guide structure, optimizing thermal management efficiency.

4. Process Innovation Trends

Intelligent Mold System: Integrates an AI-powered springback compensation algorithm (improving accuracy by 60%) and digital twin technology to enable virtual commissioning and real-time monitoring. Composite processing technology: Electromagnetic-assisted stretching reduces friction by 40%, while a combination of hydroforming and mechanical stretching improves material fluidity.

The automotive industry's reliance on precision sheet metal continues to deepen, especially in the transition to new energy and intelligent manufacturing, where its high flexibility and low cost advantages are becoming increasingly significant.
