Shan Wei, Quality Manager, Qianchao Senwei Precision Engineering Department
Understanding product quality status, exploring process improvements, addressing user feedback issues... These tasks may seem routine, yet Shan Wei has been committed to them for a decade. Every day, he makes several trips to the production floor, leaving no product defect unnoticed—because only in this way can he feel truly “at ease.” He remains steadfast in his role as the guardian of quality, building a solid quality defense line for the company.
Meticulous Refinement: The Transformation from Operator to Quality Expert
In 2014, Shan Wei joined the company as a CNC machine operator. Thanks to his diligence and hard work, he quickly stood out and was transferred to the position of inspector. Faced with a completely new field, Shan Wei didn't back down; instead, he started from scratch, learning the professional knowledge of quality management and rapidly mastering the skills required for his new role.
Shan Wei deeply understands that quality work affects the entire operation—every single step must be meticulously controlled. To perform his job more effectively, he proactively learned the production processes involved in CNC machining, quenching, and other procedures, mastering the technical essentials of each stage. He strictly adhered to operational documents when verifying product parameters, ensuring consistent quality in mass production. He also actively collaborated with the company on new-product trials, collecting, compiling, and analyzing data on product defects, and developing improvement plans that significantly reduced the defect rate. “Quality inspection allows for no room for even the slightest carelessness,” and not a single minor scratch or the most subtle dimensional deviation could escape his keen eye. Thanks to his outstanding performance, Shan Wei was successively promoted to team leader and then to quality supervisor, successfully making the transition from technical operator to quality management professional.
On-site Problem-Solving: Upholding the Quality Lifeline with Professional Standards
The production site is the place that Shan Wei knows best. No matter what kind of problem arises, he never shies away from it; he always rushes to the scene at the first opportunity and promptly formulates measures to track and resolve the issue.
Once, during product processing, a problem arose: the center hole became elliptical instead of round. How could we pinpoint the source of the issue among so many production steps? Shan Wei carefully examined the production process of each step and, using a reverse-engineering approach, inspected every batch of products. Eventually, he identified the root cause—the center hole was prone to impact damage during transportation. He immediately organized an optimization of the transportation process, completely resolving the problem.
Traditional inspection equipment requires removing the tool for measurement, which often leads to premature tool wear and disposal. “If we could measure directly without removing the tool, we’d avoid the wear and tear caused by repeated tool removal and installation,” said Shan Wei after observing the on-site operations. By adopting a handheld measuring device and upgrading the measurement method, they’ve significantly reduced material waste and greatly improved measurement accuracy.
“There are no shortcuts to quality improvement—only by being deeply rooted in the field can we find the answers.” This is a phrase that Shan Weichang often has on the tip of his tongue. Over the past year, he has completed 16 quality improvement projects covering various aspects such as product intrinsic quality, surface defects, tooling methods, and dimensional accuracy, successfully reducing the defect rate of multiple products to zero.
System Innovation: Building a Long-Term Quality Management Mechanism
In Dan Wei’s view, excellent quality management cannot rely solely on individual or short-term efforts; rather, it requires establishing a scientific and sustainable system and mechanism. In 2024, the Precision Engineering Department achieved an outstanding result—a 100% pass rate in 9N user reviews—clearly demonstrating the fruits of its quality-management system development.
In terms of quality management, Shan Wei implements a “root-cause analysis system” to systematically summarize and document previously encountered issues, thereby preventing their recurrence at the source. At the same time, he promotes a management mechanism featuring “daily inspections, weekly reports, and monthly training,” ensuring that quality awareness is deeply ingrained in everyone’s mind and that quality management is consistently and persistently pursued.
In terms of personnel management, Shan Wei actively implements the “mentorship” system, passing on knowledge to his apprentices in areas such as blueprint interpretation, inspection tool usage, and equipment operation, thereby helping new employees quickly acquire the necessary operational skills. During the weekly Monday meetings, he uses visual aids to highlight typical defects, enhancing operators’ quality awareness throughintuitive visual comparisons. Moreover, he systematically collects quality incidents into a case library and promotes continuous employee improvement through a dual-track approach combining "assessment and training."
“We rely on strictly following standard operating procedures every day—not on last-minute突击 efforts,” said Shan Wei. “Only by making everyone a guardian of quality can we truly achieve zero defects.”
There’s no end to quality—it’s all about continuous improvement. Shan Wei has always approached his work with a rigorous attitude and safeguarded quality with an earnest, meticulous approach. “I want to do well every single thing I do each day and take each step firmly and steadily,”—this is the heartfelt sentiment of him, a true “guardian of quality.”
