Quality Assurance

Qunmao Display manufactures products from initial design, through production, testing and packaging, to transportation and after-sales service. Quality is strictly monitored in accordance with national, industry and enterprise standards for factory inspection.

1. Raw material Procurement

To guarantee the quality of raw materials, our company's procurement is subject to rigorous evaluation by a qualified party. Only after passing inspection can incoming raw materials be warehoused. This ensures that the rate of qualified warehousing reaches 100%. The company prioritises purchasing from national key designated enterprises of high-quality products. A layer-by-layer customs inspection and audit system is in place to ensure this.

2. Production

To guarantee the quality of products, each production stage is rigorously controlled. Workers install a quality tracking system, and our company has introduced advanced equipment and production technology. This provides a solid foundation for the production of high-quality products.

3. Inspection

Our company maintains strict control over the inspection of products to ensure that they are not released for use or leave the factory without inspection. The technicians of the Quality Inspection Department conduct quality inspections on the production process and finished products in accordance with the technical terms of the products, design drawings and relevant standards and quality specifications. They issue the corresponding inspection reports and relevant records after passing the inspection.

4. Control of unqualified products

Our company employs three inspection systems to control unqualified products: self-inspection, mutual inspection and special inspection. These systems are designed to prevent unqualified products and to take effective corrective and preventive measures to eliminate actual and potential unqualified factors. They are also used to prevent product quality problems.

5. Packaging and transportation

The handling, packaging and delivery of the product during the moulding process affects the quality of the product in all aspects of the control process. This is to prevent product damage and ensure that the final acceptance of the product is in accordance with the signed contract and the relevant requirements of the product packaging and protection. This is to ensure that the product is transported to the customer's destination in an intact and undamaged state.

Quality Control

Qunmao Display adheres to the principle of "operating with standardized processes and speaking with testing data" to carry out comprehensive quality management of products. This is in accordance with the ISO 9001 quality management system, which has been established to provide a perfect quality assurance system. This enables us to achieve sustainable development with quality and efficiency.
