Sheet metal processing of aluminum: technical points and industry trends
Aluminum is widely used in automobiles, aerospace, electronics and other fields because of its lightweight, corrosion-resistant and easy-to-process properties. Sheet metal processing is one of the key processes for aluminum forming, involving cutting, bending, welding and other links. This article will analyze the key points of aluminum sheet metal processing technology based on recent industry hot spots, and compile relevant data for reference.
1. Core technology of aluminum sheet metal processing
Aluminum sheet metal processing mainly includes the following steps:
| Process name | Technical points | Applicable scenarios |
|---|---|---|
| laser cutting | High-precision, non-contact processing, suitable for complex contours | Electronic product casings, auto parts |
| Bending and forming | The amount of rebound needs to be controlled, usually using a compensation algorithm | Chassis and bracket parts |
| welding | Mainly TIG/MIG welding, oxidation needs to be avoided | Aerospace structural parts |
2. Recent industry hot spots and data
According to the search data of the entire network in the past 10 days, the hot spots in the field of aluminum sheet metal processing are concentrated in the following aspects:
| Hot keywords | Search volume (daily average) | Related applications |
|---|---|---|
| New energy vehicle aluminum sheet metal | 12,500 times | Battery tray and body weight reduction |
| Aluminum sheet metal 3D printing | 8,300 times | rapid prototyping |
| Environmentally friendly aluminum treatment | 6,700 times | scrap recycling technology |
3. Technical challenges and solutions
Common problems in aluminum sheet metal processing include:
1.rebound control: Aluminum has a low elastic modulus and is prone to rebound after bending. The solution is to adjust the mold parameters through multiple trial folds, or use CNC compensation technology.
2.Surface scratches: Aluminum material is soft and special clamps and protective films are required. The "markless processing" process recently launched by a company can reduce the scratch rate by 70%.
3.Welding holes: Argon gas shielded welding is used and environmental humidity is strictly controlled to reduce pore defects.
4. Outlook on future trends
Combined with industry trends, aluminum sheet metal processing will show the following trends:
| trend direction | technological breakthrough | Estimated time to spread |
|---|---|---|
| Intelligent processing | AI adjusts processing parameters in real time | 2025-2026 |
| Composite process | Laser cutting + bending integrated equipment | Has entered the commercial stage |
| green manufacturing | Low temperature sheet metal forming technology | Experimental application in 2024 |
Advances in aluminum sheet metal processing technology will continue to promote the development of related industries. Enterprises need to pay attention to technological upgrades in automation, environmental protection and other directions to cope with changes in market demand.
