Analysis of main barriers to entry of precision metal parts industry
The manufacture of precision metal parts is the basis for the manufacture of various types of precision instruments and equipment, and its development level is closely related to a country's technological level and the level of manufacturing development. In the early days, the manufacturing of precision metal parts was monopolized by industrialized countries such as Europe, America and Japan. Most Chinese manufacturing companies were in the stage of outsourcing and learning of non-core products. In recent years, in the context of global economic integration and the accelerated process of international industrial transfer, large-scale enterprises at the end of the industrial chain have begun to seek and cultivate precision machining capabilities and strict A parts supplier with excellent quality control ability, independent research and development ability and fast response speed. Through the absorption of introduction and independent innovation, my country's parts manufacturing enterprises have emerged a number of enterprises with precision manufacturing technology and fine quality management as their core capabilities, which can cooperate with supporting enterprises in the industrial chain to conduct joint research and development, and the precision metal parts industry has achieved considerable development. .
The precision metal parts industry is a technology-intensive industry with high technical barriers. This industry serves a wide range of customers, involving many industries such as equipment, energy, medical care, finance, communications, etc. Customers in various industries have different needs for precision manufacturing products, and related products have a wide variety of applications with complex processes, new processes and new materials. With endless features, enterprises in this industry need to have the ability to provide customers with serialized manufacturing services in the manufacturing process, involving fine wire forming, high-precision turning and milling composite forming, high-speed continuous stamping, metal insert injection molding, metal powder injection molding , 3D bending and forming of pipe fittings, micron metal wet drawing and other precision metal parts forming processes and precision metal parts assembly processes. With the rapid development of the industry, enterprises with higher technical level and scale will have stronger competitive advantages, so the industry has certain technical barriers.
Domestic situation of optical fiber connector
At present, with the continuous development of the domestic communication industry, optical fiber communication has entered the stage of practical application, and the scope of application is getting wider and wider. For optical fiber connectors used in optical communication systems in my country, either imported connectors are used, or so-called "parts" such as imported ceramic sleeves and peripheral metal parts are assembled in China, or according to the imported foreign technology and Key equipment is produced, mainly FC-type fiber optic connectors. In view of this situation, the author recommends the following.
General structure of optical fiber connector
The main purpose of fiber optic connectors is to connect optical fibers. Optical fiber connectors, which have been widely used in optical fiber communication systems, have many types and different structures. But on closer inspection, the basic structure of various types of fiber optic connectors is the same, that is, most fiber optic connectors are generally realized by high-precision components (composed of two pins and a coupling tube). Alignment of optical fibers.
