The development trend of automotive trim system
The development trend of "new Four Modernizations" in automobile industry also puts forward new requirements for the design and development of trim system. As one of the important subsystems of interior and exterior decoration, the trim system has shown remarkable features such as diversified process and intelligent parts while conforming to this development trend.
Process diversified trim system involves more than 20 kinds of molding process and surface treatment process, which is itself the "material library" and "process library" of interior and exterior decoration system. In recent years, with the progress of technology, more and more new processes are applied to the trim system, showing a trend of economic and quality oriented development.
Water assisted forming
Hydraulic auxiliary molding can be the luggage rack longitudinal beam, front and rear bracket, front and rear trim cover and other sub-parts integrated into integral parts. The picture shows a luggage rack made of BASF material. From the current more than ten seed parts simplified to five or six seed parts, auxiliary molding greatly simplifies the types of sub-parts and internal assembly relations, and eliminates the process of polishing aluminum profiles, can achieve about 35% cost reduction and about 50% weight reduction, the follow-up will further expand the scope of application.

Color band injection
Using colored raw materials directly injection molding, molding products to achieve the surface treatment effect of spray paint, can replace the corresponding color of the paint process. Compared with spraying process, this process has the advantages of more efficient, more environmental protection and lower cost. At present, this process has been mass-produced in the wheelbrow assembly and anti-scratch strip assembly of some new energy models. In the future, more spray painting parts will be replaced by color injection.
High light injection
Direct use of high light material injection molding, at the same time for mirror level polishing of the mold, so that the parts out of the injection to achieve high light effect, can replace the complex high light spraying process. Compared with the high light spraying process, the process has the advantages of more efficient, more environmental protection, more free modeling and more cost saving. Future A/D column trim assembly, tail door spoiler assembly, rear plate trim assembly, signage and other parts will further apply this process.
Whether from the growth space of Chinese auto industry or the rules of industrial structure adjustment and upgrading of Chinese auto parts industry, there will still be great space for Chinese auto parts industry in the coming years.
From the perspective of structure, automotive exterior parts mainly include trim, trim, functional structure, body structure, chassis structure (new energy vehicle battery box), lights, door handles, sunroof, etc.
Do you understand the selection, application and future of automotive interior and exterior decoration materials?
With the rapid promotion of China's automotive industry status in the world, people's ability to comprehensively evaluate the performance of automobile products has been strengthened, and the requirements for the shape and structure of automobiles have become more stringent. Automotive interior and exterior decoration products are not only an element, but also a product highlight. In order to meet the requirements of users for car comfort and environmental protection, in addition to the extraordinary overall structure design, the selection of automotive interior and exterior decoration materials is also the key.
Car exterior trim refers to the parts of the body that play the role of protection and decoration. It is not only the appearance parts (such as the hub decoration cover can improve the brand image of the car, and all kinds of decorative strips can enhance the vehicle beauty), but also the safety parts (such as the bumper can absorb energy, reduce the damage of the body), or the functional parts (such as the fender can prevent the wheel rolling sand and sound insulation). So the exterior parts play an important role in the auto parts system.
The black edge and flower design of the front and rear wind window assembly are directly related to the driver's vision and the brightness and darkness of the interior light, affecting the evaluation of the vehicle quality sense. The main function of the black edge includes two aspects: to protect the glass glue from being exposed to the sun, to prevent the aging of the glass glue leading to the fall off of the front window; Secondly, the black edge can block the trim, the inner rearview mirror or sensor bracket, so that the vehicle is more beautiful. The flower point is located inside the black edge, the main function is to act as the transition from the black edge to the transparent glass, weakening the visual mutation; In addition, the flower point can also contain the black edge to create deviation. It can be seen that the design difficulty of the black edge and the flower point is to ensure the beauty while matching well with the peripheral parts. The flower diagram is shown in the figure.
The company is a professional plastic electroplating manufacturers. Founded in Zhaohe 38 years (1963), it is Japan plastic plating technology industrialization period. Through more than 50 years of development, has become the top plastic electroplating manufacturers in Japan. In Japan, in order to achieve the perfect combination of electroplating technology and the beautiful natural environment in Nagano Prefecture, the company treated and recycled the product, drainage and waste liquid, creating an ideal environment-friendly electroplating business.
In China, which has the world's automobile market, in order to meet the needs of customers, a factory was built in the electroplating industrial base of Yamen Town, Jiangmen City, Guangdong Province, China. Like the Japanese headquarters, the company takes care of the environment as its own responsibility, uses skilled and advanced electroplating technology, implements high-quality and diversified electroplating production, and provides high-quality services to global customers.
