at present, the cable industry generally uses 80 models of high-speed extruder production lines for BV2.5 civil wires, with the fastest extrusion speed reaching about 230 m/min, this is already the highest extrusion speed output in the industry. The same regular rubber cable continuous vulcanization production line is a "one out one" mode, that is, one production line and one host can only produce one line at the same time. In the face of fast production pace, busy production tasks and limited production sites, how to improve production efficiency and equipment utilization is an urgent technical problem to be solved in the cable industry.

in order to actively solve the technical bottleneck, after repeated demonstration and discussion, the company has conceived to improve the production process method in the direction of double improvement of output and production efficiency, I .e. on the same main machine of one production line, the "one out two" production mode of two lines is produced at the same time, reaching a production speed of 460 meters per minute (230 m/min * 2) and reducing the number of operators by half, achieve 2 times the production capacity.

a seemingly simple idea, however, the whole production line needs to be comprehensively adjusted in all aspects of setting-out, extrusion, mold, cooling, take-up, etc. The research and development process is not smooth sailing-just modifying the mold has been tested back and forth more than ten times. After repeated debugging of key technologies such as mold, speed and angle by the technical research and development and production team, the successful test of the "one out of two" production mode was finally realized.

after testing, under the "one out of two" production mode, the production speed of the two lines both reaches 230 m/min. under the same production line, the production efficiency is increased by 100, the output is increased by 100, the number of operators is reduced by 2, the energy consumption of water and electricity is reduced by 60%, the land use of the production site is saved by 50%, and the "double efficiency and output are realized, energy consumption, personnel savings" win-win results.

In recent years, the company's business development momentum is good, sales scale continues to achieve leapfrog growth. Among them, several major innovative R & D projects continue to tackle tough problems in various technical fields, more effectively promote business development, and achieve breakthroughs in economic benefits and brand influence. As of July 31 this year, the company's revenue totaled 12.326 billion yuan, an increase of 27.19 percent over the same period last year, ranking among the top in the country. After the "one out of two" production process technology model is fully replicated and promoted, this potential will continue to move forward.

In the future, the company will continue to be based on the platform of the Cable Research Institute, adhere to innovation-led development, continue to carry out applied research based on problem-oriented and market-oriented, continue to promote the pace of production, education and research, strengthen independent research and development capabilities, and accelerate innovation Achievement transformation to achieve high-end, branding and internationalization of cable products.
