What is the laser weakening technology?

The laser weakening technology uses the high energy of the laser to focus the laser beam to a range of approximately 0.2 mm, obtaining a power density of up to 108 ~ 1010 W/cm², or even higher, and hitting the instrument panel by means of fixed frequency pulses. The thickness of the material becomes thinner so that it can preferentially fracture when subjected to external impact.

Laser weakening technology in the automotive industry

Airbags are only used once in the entire life cycle of a vehicle, but it is this single use that can make the difference between life and death for the driver. Therefore, the production process of the airbag itself has to be safe and precise to ensure that the product meets the design requirements for the only time it will be used.

• Traceability

The fifth generation of HGTECH's JRC series of automotive airbag laser weakening equipment is equipped with a self-developed fully closed-loop control system, which precisely records the production process, calculates and stores it in a database by setting up a series of quality inspection points to ensure that no defective components are selected and that the product is 100% data traceable, so it can ensure safe driving.

• High safety

When an airbag explodes, the airbag will give the cover an instantaneous and enormous force, pushing the airbag cover along the airbag line to open; therefore, the thickness of the airbag weakening line plays a vital role in the protection of life and safety. If the remaining thickness is too thin, it will lead to the appearance of the dashboard traces can not achieve the effect of invisibility, and affect the life of the dashboard; if the remaining thickness is too thick, it will affect the blasting effect, can not follow the established track in time to pop out to protect people's life safety.

The core component of HGTECH's fifth generation of automotive dashboard laser weakening equipment, the independently developed residual thickness sensor closed-loop control system, can ensure that the entire weakening process is highly precise and fully controllable, and the residual thickness of the point-like weakening can be uniformly controlled within 0.15±0.05mm accuracy, so that the safety factor when blasting is greatly enhanced and let airbags fully protect lives.

With years experience in the industry, HGTECH has many mature application cases and can provide customized design solutions and localized after-sales services for customers.

In the future, we will keep up with the trends, optimize and upgrade the airbag laser weakening equipment, continue to increase the research and development of core technologies such as control systems, and help the automotive industry to grow.
