In response to the sustainable development of quality, productivity, cost control, and environment, there is also a growing demand for product customization, market flexibility, and faster market launch. The corresponding solutions are increasingly dependent on industrial automation. The electromechanical integrated automatic machine adopts automatic installation, which is faster to install and has better production control, thus meeting customer needs more easily. And being able to control and improve the functions of the machine means that the process is more stable, information is transmitted in real-time, and timely corrections are made. Automation is beneficial for protecting the environment, saving energy, and reducing pollution such as waste, air, and noise. DOS products have been widely used in automation fields such as warehousing and logistics, power plants, and railways.
