Dec 21,2023
Although the spring industry is a small industry in the entire manufacturing industry, its role cannot be underestimated. The country's industrial manufacturing industry and automobile industry must accelerate the development, and the spring industry, as one of the basic parts and components, needs a more advanced period of development to adapt to the rapid development of the country's entire industry. At present, the output of China's spring industry tends to be saturated. According to expert statistics, China's spring production has reached 4 billion pieces. There are 21 categories and more than 1600 varieties of spring products, mainly including valve springs, suspension springs, diaphragm springs, damping springs, hydraulic springs, oil pump springs, butterfly springs, high temperature springs, circlip springs, tension springs, torsion springs, compression springs, scroll springs and heterosexual springs. At this stage, China's spring products are mainly low-tech general springs, and only a few large-scale high-tech products such as heterogeneous parts and cross-sectional products can be produced.

In recent years, China's spring industry has achieved rapid development, and the technical level and quality level have been greatly improved. As a general-purpose component, the spring function covers many aspects such as shock absorption, energy storage, control, and tension maintenance. The application fields involve various fields of the national economy, including aerospace, electric power and nuclear power equipment, high-speed railways, automobiles, medical equipment, Daily hardware, toys, etc. In recent years, the rapid development of the national economy has driven the rapid growth of China's spring industry, the demand for the upgrading of machinery and equipment and the demand for the improvement of the performance of the supporting host have a greater role in promoting the technical level and quality level of the spring industry.
The company's hot coil cylindrical spiral compression spring in strict accordance with the material inspection, blanking, end grinding tip, steel seal identification, heating, coil spring, quenching, tempering, shot peening, flaw detection, strong pressure, grinding end face, inspection, surface treatment, packaging and other processes for production.
In order to better guide production and ensure product quality. The technical department of the company has carefully prepared the process documents to form a more complete process document system. In the spring manufacturing process in strict accordance with the requirements of the process documents, so that the entire manufacturing process in a controlled state. In addition, the technical department also organized the process verification of the hot coil production line, including end heating, bar heating, tip grinding machine, spring coiling machine, quenching tank, tempering furnace, flaw detector, shot blasting machine, force measuring machine, fatigue testing machine, etc. The process verification results meet the technical and production requirements. Natural gas is used as energy source in rod heating, which is more energy-saving and effective than traditional electric heating. And the key processes of people, machines, materials, methods, ring according to the procedures for capacity certification, key parts, key processes must go through self-inspection, mutual inspection, special inspection. The special process shall be controlled according to the requirements of JC/CXW-23 Production Process Control Procedure. Special procedures monitor the process and record the necessary items.
