Problems solved by technology

[0002] With the continuous advancement of science and technology in different fields, more and more undeveloped fields need people or equipment to enter. For these special environments, the performance requirements of equipment parts are extremely high. The main purpose of fasteners is to connect various Components play a very important role in the connection of equipment, so their performance and strength have a very, very large impact on the service life of the equipment. The performance of fasteners can be improved mainly by improving the process and formulating fastener materials. Improvement and accurate proportioning of fastener raw materials to achieve. In order to ensure the production accuracy of each step in the traditional fastener production process, although sensors are used to detect in time, but there is often no unified management, so the process cannot be improved. , with the continuous development of production technology, it is now possible to monitor the entire production process through the computer. After using computer monitoring, some unnecessary detection procedures can be removed to improve productivity
