The Main Advantages of Laser Cutting Technology in Automotive Manufacturing

In order to meet the needs of export and domestic upgrading in the automobile manufacturing industry, small-batch and multi-variety vehicle production has become the norm.

The original general automotive body parts processing technology can not fully meet today's product quality and production needs, of which the laser cutting machine has the characteristics of processing high-precision, multi-hole class and shape complex features accessories, and has an irreplaceable role.

Now truck manufacturers have been equipped with CNC fine plasma cutting machines, laser cutting machines, etc., for the processing of sheet metal parts with complex shapes and high precision requirements in automobiles.

Laser cutting machines have been widely used in the automobile manufacturing industry and play an irreplaceable role for other CNC cutting equipment. Its main advantages are as follows:

1. Applicable to a variety of materials accessories

Automotive materials such as low-carbon low-alloy steel, high-strength steel, atmospheric corrosion-resistant steel, ferritic stainless steel, austenitic stainless steel and aluminum alloys can be processed by laser cutting equipment, and its processing range can cover almost all materials of sheet parts in automobiles.

2. High processing precision

Laser cutting equipment has higher processing precision than other cutting equipment, and can meet the processing requirements of high-precision parts.

3. Narrower cutting slit width

Smaller cutting slit is good for reducing the spacing of accessories, improving material utilization and producing less cutting slag when cutting.

4.High material utilization rate

When cutting parts, it is possible to cut different parts of the same plate thickness and material, so as to make full use of the raw material's edge residue.

5. Low cutting roughness value

In cutting the same material parts, compared with other equipment, laser cutting equipment cutting roughness value is low. In the automotive manufacturing industry, different CNC cutting equipment processing workpiece section roughness is significantly different, laser cutting section roughness value is low.

6. Small heat-affected zone

In the laser cutting process, the edge of the material to be cut will produce a heat-affected zone due to the heat. But laser cutting than other processing methods of energy concentration heat input is small, compared with fine plasma cutting and flame cutting, the heat-affected zone is relatively small. This feature of small heat input is very important for ferritic stainless steel and high-strength steel that is prone to grain growth and hardening tendency, which is conducive to improving the quality of the weld.

7. Low cost of laser cutting for small batch production

In high-volume production, choose the process of mold drop for processing, high-volume production, the cost of making the mold is evenly spread to each fitting, its production costs are lower. However, if it is a small batch production, the processing process of mold blanking, not only the production cycle of the mold is long, can not meet the timeliness of the parts processing, and the mold production cost is equally spread to each accessory, the processing cost is relatively high.
