Shanghai Yimei Quality Assurance System Introduction

June 04, 2019

"Long life, reliable" is the consistent aim of Shanghai Yimei Electronic Technology Co., Ltd. (website: http://). Shanghai Yimei has obtained CE certification for all products in 2008 and is RoHS compliant. More than 90% of the products are sold to Europe, North America, Asia and other countries and regions. Shanghai Yimei also joined the Shanghai Semiconductor Lighting Engineering Technology Association, and the waterproof LED flexible strip project developed by the company won the “2008 China LED Technology Innovation Award”.

In order to further improve product quality and market competitiveness, and promote quality management work to a new level, and in line with international standards, Shanghai Yimei absorbs advanced enterprise quality management concepts at home and abroad, after successfully passing ISO9001: 2000 certification, high-paying employment Under the supervision of experts, the products are strictly produced in accordance with the international quality standard lS09001:2000, thus forming a complete set of quality assurance system.

In order to implement the quality policy of “long life, reliable” and achieve quality objectives, Shanghai Yimei started from all aspects of product manufacturing, namely design, material selection, material inspection, production process, warehouse inspection, warehouse inspection and after-sales service. A complete, scientific and effective quality assurance system.

In the process of system operation, the entire production process is implemented with the concept of Shanghai Yimei Product Quality Assurance, and the effectiveness and suitability of the system are continuously reviewed internally, and effective corrective and preventive measures are taken in time to improve the company's entire manufacturing process. Always under control.

1. Product design and development: Shanghai Yimei strictly follows the requirements, standards and quality assurance requirements of customer information feedback in product design and R&D.

2. Manufacturing: Shanghai Yimei has advanced and complete production equipment, and also develops, introduces and absorbs advanced design, research and development, and manufacturing processes. In the production of products, strong pre-monitoring is carried out on factors such as people, machines, materials, rings, methods, and tests that affect the quality of the process. For the key work that directly affects the physical quality of the product, the special process sets the control point of the workshop to control, and supplemented by scientific and effective operation quality documents, process specifications, guide and standardize the operator to operate and check. At the same time, the operator is trained in the quality system and establishes the quality viewpoint of “resolutely not letting the defective products flow into the next process”, thus ensuring that the production and service processes of the products are under control from beginning to end.

3. Inspection and testing: Shanghai Yimei implements the “three inspections” system combining self-inspection, mutual inspection and special inspection, and strictly controls the quality. The quality inspection department conducts performance tests and tests on each product in strict accordance with the inspection points and inspection procedures specified in the quality plan. When the product is stored in the warehouse, the inspector of the finished product also checks the product to ensure that the item is complete and the packaging quality meets the requirements. The strict, efficient and complete inspection system has finally guaranteed the product quality of Shanghai Yimei.

Shanghai to the United States consistently committed to "long life, reliable," from beginning to end conscientiously, strive. Shanghai Yimei has established a sound quality assurance management system, timely feedback, statistics, analysis and treatment of quality issues, and effective corrective and preventive measures to ensure that Shanghai Yimei quality system is scientifically and reasonably fully operational. Realize and promote the stability and improvement of product quality.

The pursuit of excellence is the ideal of Yimei, and customer satisfaction is the goal of Shanghai Yimei. Shanghai Yimei will always be committed to ensuring and improving product quality by continuously improving the quality system and making it work normally and effectively.
