As part of the passive safety system, automotive airbags play a very important role in improving passenger safety. These various airbags require efficient and flexible processing solutions.
Laser cutting has been widely used in the field of automotive interiors. Such as the cutting and marking of fabrics such as car carpets, car seats, car cushions, and car sunshades. Today, this flexible and efficient laser processing technology has been gradually applied to the cutting process of airbags.
The laser cutting system significantly advantages compared with the mechanical die cutting system. First of all, the laser system does not use die tools, which not only saves the cost of the tooling itself, but also does not cause delays in the production plan due to die tools manufacturing.
In addition, the mechanical die-cutting system also has many limitations, which stem from its characteristics of processing through the contact between the cutting tool and the material. Different from the contact processing method of mechanical die cutting, laser cutting is a non-contact processing and will not cause material deformation.
Moreover, laser cutting of airbag cloth has the advantage that besides the fast cuts the cloth is melted at the cutting edges immediately, which avoids fraying. Owing to the good possibility of automation, also complex work piece geometries and various cutting shapes can be easily generated.
Simultaneous cutting of multiple layers, compared to single-layer cutting, yields increased volumes and decreased costs.
Airbags are required to cut mounting holes. All holes processed with laser are clean and debris and discoloration free.
Very high precision of laser cutting.
Automatic edges sealing.
No post-processing necessary.
