There is a group of people in the entertainment industry who may not be able to name themselves, but they are indispensable in film and television works. They have no appearance or physique, and have silently worked in the entertainment industry for more than ten years, only able to play small roles and small figures. Of course, there are also some talented actors who have successfully made a comeback from grassroots roles to becoming movie stars, such as Wang Baoqiang, Huang Bo, and others, which are good examples. But not all actors can be as lucky as them. Most grassroots tricks are like small "screws", but each screw plays a crucial role and is an indispensable part.

A small screw may seem inconspicuous, but its function is incredibly important. From high-speed trains, airplanes, spacecraft, robots, to mobile phones, cameras, computers, and medical devices, screws are indispensable. Some patients even need to implant screws into their bodies. In 2000, The New York Times launched a poll called "The Best Tool of the Second Millennium in the Age of Humanity", and in the end, the inconspicuous screw even topped the list, becoming the undisputed industrial adhesive.

As long as it is manufacturing, there will be screws, and screws will involve tightening. As the backbone of digital tightening technology, Speed Digital Tightening has been committed to the research and development, production, and sales of intelligent electric screwdriver torque testers and peripheral supporting products since its establishment in 2007. Through technological research and development, the concepts of "intelligent tightening" and "digital tightening" have been constructively proposed in the industry. Their foresight has a great driving force for the transformation and development of Chinese electric screwdrivers, and has led China to enter the era of digital tightening, helping Industry 4.0 digital factories.

The professional level intelligent brushless electric screwdriver independently developed and created by it is in a leading position in the industry in terms of accuracy, intelligence, and digitalization. Firstly, the torque accuracy of its millions of tightening assemblies is accurately controlled within a standard deviation of ≤ 3%. Under normal working conditions, it can achieve Cmk ≥ 1.6, which means that there is only an error rate of 0.6 times per million screws, and the qualification rate is as high as 99.9994%. Secondly, it is also possible to freely set and adjust torque, speed, waiting time, and rotation direction within the performance parameter range according to different tightening process requirements, achieving more precise tightening. In addition, it significantly reduces operating costs, has a longer lifespan, and ensures robust power performance and torque peak output, making it an ideal digital tightening assembly process choice.

As a leading practitioner and excellent supplier of Industry 4.0, Speed Digital Tightening will continue to optimize product assembly processes based on past practical experience, reduce equipment on-site assembly problems, shorten assembly cycles, significantly improve assembly efficiency and quality, and bring innovation in tightening tools and processes to the transformation and upgrading of the manufacturing industry. At present, the company has rich application experience and successful cases. Intelligent will continue to innovate and research and develop tightening tools, providing advanced tightening tools to customers, thereby helping enterprises improve their production process quality and automation assembly level, leading industry transformation and upgrading.
