After CHINA's accession to the WTO organization, the world's major brands of automobiles poured into the Chinese market, and even established joint ventures in CHINA. Japanese automobile companies such as Toyota, Toyota, Nissan, Honda, and Mazda basically formed their own strategic deployments in CHINA. Geely, Chery, Hafei, Great Wall Motors and other national brand banners are not to be outdone, and the domestic auto industry has entered a fever pitch.
The competition in the automotive industry is comprehensive, price, quality, marketing, brand, etc. Now, to survive and develop in this highly competitive market environment, it is necessary to satisfy customers in all aspects as much as possible. The paint color of the body paint and auto parts is like the coat of the car. It is a very important factor to control the color of all parts of the car in order to satisfy the interests of consumers. It is in this situation that the Colorimeter appears on the automobile production line.
With the improvement of people's living standards, people's consumption intentions are more regionally rational, more professional and demanding. At this time, the production of a car must not only satisfy the consumer's use function, but also meet the consumer's aesthetic point of view. From the lines of the exterior of the car body to the color of the car paint parts, everything is the standard for customer evaluation. There are strict requirements for the vividness, glossiness and even the color difference between different parts of the car color. We know that the color difference meter quantifies the abstract color into numerical form, which is very convenient for analysis and adjustment. We know that the production process of the car uses a lot of equipment and is very precise and professional. These devices not only guarantee the performance and function of the car, but also ensure the appearance and color of the car. For the color control of the automotive industry, different instruments may be used in different parts. If it is an automotive parts manufacturer, general-purpose color testing equipment such as Spectrophotometer s and Colorimeters are sufficient to meet the needs. However, if you want to detect the surface color of automotive pearlescent paint, you must use a special instrument called a multi-angle Colorimeter.
With the mass adoption of colored plastic parts such as bumpers, door handles, rearview mirrors and refueling doors, it is required that the color of the body and the plastic parts have no deviation, which puts forward higher requirements for the control of the color difference of the body paint. At present, the popular method in car factories is to control the color difference by combining instrument measurement and visual inspection. Generally, a standard color sample is provided, and the color of the body and plastic parts is required to be close to the standard sample, whether it is visual inspection or instrument measurement. . There are many factors affecting the color difference of body paint, which are closely related to factors such as paint materials, spraying process, spraying equipment, and paint supply system.
The above is the detection application of Colorimeter in color management in the automotive industry, and I hope it can be used as a reference for relevant users in the industry.
