China's coating material market size: 2017 thermal spray coating market size is about 970 million US dollars
According to the degree of automation of the process technology, spraying can be divided into manual spraying and fully automatic spraying. According to the definition of spraying, the spraying industry mainly includes two aspects: spraying materials and spraying equipment. Spray materials are materials used in spray technology to obtain the desired coating on the surface of the workpiece. Spray materials can be divided into different types according to different classification standards. The common classification methods are divided according to ingredients:
Figure 1: Spray material classification
According to the “2018-2023 China Coating Industry Development Prospect Forecast and Investment Strategic Planning Analysis Report†published by Prospective Industry Research Institute, the global thermal spray coating market reached US$9.22 billion in 2017, of which Asia Pacific accounted for 21.2% of the global market share. China accounts for about half of the Asia-Pacific region, so it is estimated that the size of China's thermal spray coating market in 2017 is about 970 million US dollars.

China's spraying equipment market demand: the demand for spray guns in China in 2017 was 15.9 million
Spray equipment is a special tool that covers the protective or decorative layers of metal and non-metal surfaces. According to different classification standards, spraying equipment can be divided into the following categories:
Figure 3: Spray equipment classification
Spraying equipment includes spray guns, hydraulic drives (hydraulic oil sources such as oil pumps, fuel tanks and motors), rotating cups, etc. From the data of the spray gun market: from 2013 to 2017, with the development of construction, vehicle spraying, metal spraying, plastic spraying, wood products spraying, industrial spraying, nano material spraying, art spraying, etc., the demand for spray guns in China continues to expand. The growth rate is maintained at around 8%. In 2017, the demand for spray guns in China was 15.9 million. It is expected that the demand for spray guns in China will continue to expand in 2018-2023, but the growth rate will decline.

Development trend of the coating industry: painting robots will become the inevitable result of the development of the coating industry
With the continuous development and improvement of the spraying process, the reform of the spraying machine technology is always in progress, and the requirements of the automated industrial production are gradually improved, and the principles of safe production and environmentally friendly production are continuously implemented, and the emergence of the spraying robot becomes inevitable. And this high-tech spray equipment can also meet these requirements of various workpieces.
The spray robot, also known as the spray paint robot (spraypainTIngrobot), is an industrial robot that can automatically paint or spray other paints. The painting robot is mainly composed of the robot body, the computer and the corresponding control system. It adopts the joint structure of 5 or 6 degrees of freedom, the arm has a large movement space, and can make complex trajectory movements. The wrists generally have 2 to 3 One degree of freedom, flexible movement. The more advanced painting robot wrist uses a flexible wrist that can be bent and rotated in all directions. Its action is similar to that of a human wrist. It can easily penetrate into the inside of the workpiece through a small hole and spray the inner surface. The painting robot is generally driven by hydraulic pressure, and has the characteristics of fast action speed and good explosion-proof performance. It can be taught by hand teaching or point display. Painting robots are widely used in the production of automotive, instrumentation, electrical appliances, enamel and other processes.
The main advantages of the painting robot are as follows:

It can be seen that with the continuous upgrading of the spraying process, the requirements are constantly increasing, and the transformation of the painting robot is also ongoing. It is believed that with the continuous development of science and technology in the future, the modern spraying process will also produce a qualitative leap.
According to GGII data, in 2016, the sales volume of China's painting robots was 45,000 units, a year-on-year increase of 32.35%. The size of China's coating system integration market reached 7.21 billion yuan, a year-on-year increase of 22.62%. GGII expects that the scale of the coating system integration market will maintain steady growth in the next four years, with a growth rate of over 20%. By 2020, the sales volume will exceed 13,000 units, and the market size is expected to exceed 12 billion yuan.
