Introduction

At a critical juncture in the company's full-industry-chain strategic advancement, there is a female worker in the cable workshop who safeguards the "first checkpoint" of cable production with focus and craftsmanship. As the "threader" in the extrusion process, she weaves the precise structure of the cable cores with her hands. Every meter of meticulously formed cable core lays a solid foundation for the subsequent processes of wire twisting and cabling.

Strict control over the first process ensures precision down to the millimeter.

The extrusion process is the 'starting line' of cable production, and the precision in making the cable core directly determines the cable's quality performance and service life. Li Xiaojuan understands this very well. For more than ten years, she has been dedicated to frontline work, showcasing 'millimeter-level' precision skills in front of the extrusion machine. To ensure the insulation layer fits the conductor perfectly, the first thing she does when starting her work is repeatedly adjusting the mold temperature, screw speed, and traction speed. Even a temperature difference of 0.1°C or a speed deviation of 0.5 revolutions per minute cannot escape her 'keen eye.' 'The first process is like laying the foundation of a house; if the foundation is crooked, no matter how good the house is, it will still be unsafe,' Li Xiaojuan often says.

Produces 100,000 meters a day, 270,000 repeated tests with zero defects

In Li Xiaojuan's work log, a set of numbers stands out: 100,000 meters of cable core produced in a single day. Over the course of a year, the company's drag chain and drag chain cable life test bench conducted 270,000 repetitive tests, and neither the drag chain nor the cables showed any quality defects. To achieve such a 'hardcore target,' she invented the 'three checks and three observations' work method—before starting the machine, check the raw material moisture, check equipment parameters, check mold wear; during production, observe the uniformity of cable core color, check the fluctuation of insulation layer thickness, and monitor the stability of traction speed. It is precisely her strict self-discipline over more than a decade and rigorous control over product quality that has made the company's cable products a 'quality benchmark' in the industry for specialized cables.

From 'craft inheritance' to 'technological innovation,' let craftsmanship shine through innovation.

  

As a 'master worker' in the workshop, Li Xiaojuan not only excels in her field, loves her work, and perfects her skills, but also transforms her expertise into 'sparks' to pass on to the younger generation. She leads the 'Extrusion Task Force,' regularly conducts on-the-job training, combining theory with practice while balancing quality and safety. During the company's push for an 'intelligent cable full-industry chain upgrade,' she takes the lead, conducting joint research on the applicability of new polymer insulation materials in the extrusion process, contributing to the improvement of product quality and processes. 'Craftsmanship is not about rigidly adhering to tradition, but about using new methods to perfect old skills.' Her determined gaze shines with the light of innovation.

Day after day, through the changing seasons, the roar of the extruder served as background music as Li Xiaojuan traced the age rings of a craftsman in the arcs of the cable cores flowing through her hands. Every meter of cable core she handled was an interpretation of 'Quality is Life'; every contribution she made was a testament to her commitment to 'Intelligent Mining Manufacturing.' In the confined space of the cable workshop, she used the skill of 'threading the needle' to embroider a long scroll of the miners' craftsmanship.
