There is an explosion, the ability to turn the tide, the maximum protection of your safety, this is the car passive safety technology in the airbag - the "protection god" of life.
Early cars used split mounted airbags with noticeable color differences that seriously damaged the overall aesthetics of the dashboard. With the technological upgrading of the automotive industry, luxury cars up to one million level, scooters as low as tens of thousands of yuan, and the configuration of invisible airbags in the passenger seat of the dashboard has become the mainstream.
How should safety manufacturers choose in cutting process applications where invisible airbag weakening lines for automotive instrument panels are used?
CNC milling, hot knives, cold knives or laser weakening?
Laser weakening processing as a modern precision machining method, compared with the traditional processing methods (CNC milling weakening, cold knife, hot knife weakening, etc.), it is a non-contact, no cutting force, small thermal impact of the processing method, suitable for the current general majority of materials, such as violinum leather materialS TPO, PU, vacuum forming epidermal materials PVC, ABS, etc.
The hard instrument panel laser weakens the solid sample
Soft instrument panel laser weakening solid sample
It can process both a single material such as a PP injection molded dashboard upper body, or a viscopied instrument body body that is cross-cured by the skeleton, foam layer and epidermis. Therefore, the laser weakening processing process has a wide range of materials and obvious advantages.
Popular science small class, what is the laser weakening process?
Laser weakening process is the use of the laser has the high energy, through the focus of the laser beam in the range of about 0.2 mm, to obtain up to 108 ~ 1010W / cm, or even higher power density, through the way of fixed frequency pulse hit on the dashboard, the focus of the material in the absorption of laser high energy after rapid vaporization, the formation of penetration or non-penetration (as needed) of the small hole, the thickness of the material in these small holes area thinner, the fracture strength is reduced, so that when subjected to external impact, priority fracture.
From 0 to 1 fill the domestic gap
Subject to the lack of core technologies such as the weakening of the residual thickness full closed-loop control system, the laser weakening equipment of the airbag line in the past was monopolized by foreign monopolies, and the customers of the mainland automotive industry were deeply troubled by its "expensive price, long supply cycle, after-sales service can not be processed in time and the cost is high, and the price of supporting fixtures is high".
In 2008, Huagong Laser, as the "national team" in the field of lasers, formed an "iron triangle" with Huazhong University of Science and Technology and a well-known domestic car company, and successfully developed the first set of domestic laser weakening processes and equipment suitable for multi-variety production of automotive instrument panel airbags with completely independent intellectual property rights, which met the manufacturing needs of high precision, high stability, high flexibility and aesthetics in the automotive field, and became the only two enterprises in the world and the only one in China that can provide laser weakening processes and equipment.
The launch of the first set of domestic laser weakening equipment has filled the technical gap in related fields in China, broken the industry monopoly of foreign enterprises in one fell swoop, forced the import price of products to be reduced by more than 20%, and vigorously promoted the development of the mainland automobile manufacturing industry.
The first set of domestic automotive instrument panel laser weakening equipment
At present, the first laser weakening equipment of Huagong Laser has been running smoothly at the customer site for 13 years, and has gradually formed batch sales, and the market share has been expanding. Through the strength, it is proved that the processing accuracy, reliability, stability and other performances of domestic equipment are comparable to the level of imported equipment.
Technology Empowerment Safety is more important than anything else
Airbags are only used once in the entire life of a car, but it is this only use that determines the life and death of the occupant. Therefore, the production process of the automotive airbag itself should ensure safety and precision to ensure that the product meets the design requirements in the only use.
01
Traceability
The relevant national laws and regulations stipulate that the production data of each airbag must be kept for 15 years.
JRC series automotive airbag laser weakening equipment processing process
Huagong Laser fifth generation JRC series automotive airbag laser weakening equipment, equipped with self-developed full closed-loop control system, through the setting of a series of quality inspection points, accurately record the production process, calculate and store in the database, in order to ensure that defective components are not selected, and to achieve 100% process data traceability of the product, for safe driving "escort".
02
High security
When the airbag explodes, the airbag will give the cover an instantaneous huge force, pushing the airbag cover along the airbag line to open; therefore, the accuracy of the remaining thickness of the airbag weakening line plays a crucial role in the protection of life safety. If the remaining thickness is too thin, it will cause the appearance of the dashboard to have traces that cannot achieve the invisible effect, and affect the life of the dashboard; if the remaining thickness is too thick, it will affect the blasting effect, and it will not be able to pop out in time according to the established trajectory to protect people's life safety.
Huagong Laser's fifth-generation automotive instrument panel laser weakening equipment, its core component - the self-developed residual thickness sensor closed-loop control system can ensure that the entire weakening process is highly precise and completely controllable, and the residual thickness of the dot weakening can be uniformly controlled within the accuracy of 0.15±0.05mm, which greatly improves the safety factor during blasting, and makes the airbag become the "talisman" of life.
03
Cost-effective
Compared with imported products, domestic laser weakening equipment is not inferior in performance, and the price is more reasonable. At present, the price of imported equipment is almost 2-3 times that of domestic equipment, and the price of after-sales service is expensive.
Deeply rooted in the industry for many years, Huagong Laser has many mature application cases, which can provide customers with customized design solutions and localized after-sales service.
Customer site
Innovation is supreme, and the light is not stopped
With the increase of national regulations on safety products year by year and the rapid growth of China's automobile market, airbags will become the standard of all types of models, intelligent, multi-airbag is the inevitable trend of the development of the overall airbag system in the future, the mainland airbag market will face huge market demand.
In the future, Huagong Laser will keep up with the tide of the times, continuously 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 sail away.
