Quality Month Activities

We organize Quality Month activities from June to July every year to improve the quality awareness of all employees.

July 2026 — SINOROCK successfully completed its annual Quality Month Campaign with the theme of “Addressing Customer Feedback and Eliminating Quality Risks Across the Entire Process.”

The campaign aimed to strengthen employees’ quality awareness, encourage full participation in quality management, and build a company-wide culture where everyone values, contributes to, and continuously improves product quality.

Throughout the month, SINOROCK organized a series of activities, including quality awareness meetings, customer complaint reviews, quality risk inspections, quality knowledge competitions, professional training sessions, and internal quality communication activities. These initiatives further integrated quality management into every department and every stage of production.

Customer Feedback Drives Continuous Improvement

Customer Feedback Drives Continuous Improvement

Customer feedback is an essential source for identifying potential quality issues and improving products and processes.

During Quality Month, SINOROCK conducted customer complaint review meetings, analyzing real cases from customer feedback, identifying root causes, and developing targeted improvement measures.

Through these case studies, employees gained a deeper understanding of how product quality impacts customer satisfaction and project performance. By transforming customer feedback into practical improvement actions, SINOROCK continues to optimize its quality management system and enhance product reliability.

Quality Is Everyone’s Responsibility

Quality Is Everyone’s Responsibility

Quality is not only the responsibility of the quality department — it is a commitment shared by every employee.

During the “Everyone Talks About Quality” communication sessions, employees from different positions shared their understanding of quality based on their daily work and responsibilities.

At the same time, SINOROCK organized a company-wide quality risk inspection activity. Employees actively participated in identifying potential risks within production processes, reporting issues, and proposing improvement suggestions.

These activities helped strengthen employees’ ability to identify and prevent quality problems, promoting a transition from “solving problems after they occur” to “preventing problems before they happen.”

Improving Skills Through Learning and Competition

SINOROCK 2026 Quality Month

To further enhance employees’ professional knowledge and practical quality control capabilities, SINOROCK carried out various training sessions and competitions during Quality Month.

The “Product Matching Challenge” focused on 15 similar and easily confused product types. Participants were evaluated on their product identification accuracy and completion efficiency, improving their understanding of product specifications and classifications.

SINOROCK also organized a Quality Knowledge Competition featuring a 200-question quality knowledge database. The competition combined theoretical knowledge with real quality cases from company records, helping employees better understand quality standards and practical problem-solving methods.

In addition, professional training sessions were conducted, including:

  • Hardness tester operation training;
  • Product inspection knowledge sharing;
  • Inspection procedures and standards training;
  • Product inspection specification training.

These programs further improved employees’ capabilities in product inspection, process control, and quality assurance.

Strengthening Quality Awareness Through Real Cases

During Quality Month, SINOROCK held quality awareness meetings in different locations.

On July 13. the Quality Warning Conference was organized in Changzhou. On July 14. similar meetings were held at the Luoyang office and Luoyang branch.

Through reviewing quality-related cases and sharing lessons learned, these meetings further reinforced employees’ understanding of the importance of product quality and encouraged everyone to take greater responsibility for quality improvement.

Quality Is a Long-Term Commitment

Quality Is a Long-Term Commitment

Although Quality Month was carried out throughout July, SINOROCK’s commitment to quality improvement extends far beyond a one-month campaign.

Through meetings, practical training, competitions, inspections, and internal communication activities, quality awareness has been further integrated into daily operations.

“Addressing Customer Feedback and Eliminating Quality Risks Across the Entire Process” represents not only the theme of the 2026 Quality Month Campaign but also SINOROCK’s long-term commitment to customer-oriented quality management.

Moving forward, SINOROCK will continue to focus on customer needs, strengthen quality control throughout the entire production process, proactively identify and eliminate potential risks, and continuously improve product quality and service capabilities.

Driven by continuous improvement and a strong commitment to quality, SINOROCK will continue providing reliable, high-quality self-drilling anchor bolt products and engineering solutions to customers worldwide.
