Which China electric vertical takeoff and landing enterprise is doing better? Does everyone understand?

China mainly manufactures three companies: Anke, Ameida and Taihe Optoelectronics. Among them, Anke's photoelectric color sorter has the best quality, and Taihe's CCD is the earliest and the effect is the best. There are about 30-40 color sorters in China. Some color sorter manufacturers have been listed, and some are on the way to listing. I guess I want to know the color sorter manufacturer and then buy a color sorter. Here are some suggestions for choosing color sorter manufacturers. The bigger the manufacturer, the better. Only professionalism and innovation are the best. 1. It is best to choose a color sorter that integrates independent research and development, production, sales and service. We should have our own production site and R&D team to solve technical problems better. Only such manufacturers have the strength and ability to solve customers' problems, which is what we need. 2. Pay attention to the after-sales service of color sorter manufacturers and find a company specializing in color sorters. People who have been in a certain line for a long time are experts, and so are companies; When the company grows bigger, it will concentrate on making more profitable products, focusing on more profitable industries, such as medical care and robotics, and gradually reducing the research and service energy of color sorters. This kind of sales and service cycle is generally longer, and manufacturers specializing in color sorters will serve customers in this industry professionally and provide better services. 3. Choose factory direct sales. Dealers usually buy manufacturers' machines at low prices, and he will sell them to you whichever is cheaper, and the effect is not guaranteed. At the same time, if something really goes wrong in the later period, manufacturers and distributors will shirk each other, and you should not say it is invalid every day. This is the difference between factory direct sales and distributors. 4. Buying a color sorter depends on the future development direction. Nowadays, science and technology are developing rapidly. In big cities like Beijing, Shanghai and Shenzhen, the speed of scientific and technological development has been at the forefront of the world. Enterprises in big cities have great room for scientific and technological development, and their ability to solve problems with technology will be better than that of inland enterprises.
