How is Jieshijie Company in Hefei, Anhui?

I’m not sure if it’s the same company as Shanghai Jieshijie; Shanghai Jieshijie is really excellent. I started working at a materials company right after graduating, and after working there for 3-4 years, it’s time for me to get involved in formula modification as well

Anhui is a subsidiary of Shanghai: http://www.geniuscn.com/about.php?id=11. It has grown up alongside the development and transformation of China’s engineering plastics industry. Upholding the values and spiritual heritage associated with the hard work and perseverance required in this industry, it continues to innovate and improve itself, driven by a spirit of unity and determination, as well as a strong sense of social responsibility, in order to meet new challenges. Development History: In 1992, Yang Guisheng, the leader of the **8.5 Major Scientific and Technological Project and a doctor in engineering plastics, with the goal of changing the backward state of China’s engineering plastics industry, moved to Shanghai and founded “Shanghai Jieshijie New Materials Technology Company”. In 1993, Jieshijie was recognized as a high-tech enterprise in Shanghai. That same year, leveraging its technical advantages, Jieshijie became the first company to provide bumpers, wheel housing materials, and domestic solutions for PP1-PP10 to Shanghai Volkswagen. In 1994, it was the first to introduce AS alloy for Chulan’s air-conditioning products, as a substitute for PPO. In 1996, Jieshijie provided a complete set of solutions using thermoplastic engineering plastics to replace thermosetting materials in Haier’s dishwashers. In 1998, Jieshijie obtained the international ISO9001:1994 quality management system certification. In 1999, the company was restructured into a joint-stock company, with Shanghai Jieshijie New Materials Co., Ltd. officially established. The same year, Jieshijie received the “double high” certification for high-tech enterprises from the China Securities Regulatory Commission, the **Ministry of Science and Technology, and the Chinese Academy of Sciences. In 2000, Jieshijie obtained the ISO14001 environmental management system certification. In 2001, it passed the TS16949 quality system certification. In 2001, Yang Guisheng, the company’s chairman, was named one of China’s top ten outstanding young people. That same year, Professor Heck, a Nobel Prize winner in chemistry, was appointed as a special advisor to the company’s board of directors. In 2002, Jieshijie’s “new generation of high-temperature resistant polymer composite materials” was included in the **863 Program. In 2004, Jieshijie was recognized as a “**level key high-tech enterprise”. In 2005, it was ranked first among Shanghai’s technology companies in terms of independent innovation by the Shanghai ** authorities. In 2006, Jieshijie was approved by the ** Ministry of Human Resources to establish a post-doctoral research station. In the same year, Hefei Jieshijie was established, with a registered capital of 200 million yuan. The total investment in the facility was 430 million yuan; it covers an area of 150 mu, with a building area of over 80,000 square meters. The facility includes 40 engineering plastics production lines, 8 TPAC long-fiber production lines, 8 TPAC lightweight panel production lines, and 4 PE nanofilm production lines. In addition, a **-level R&D center and the most equipped testing center will also be established. It has become one of the largest production bases for engineering plastics and thermoplastic composites in Asia. 2007: Provided engineering plastic system solutions for Chery Automobile and established a strategic partnership with the company. 2007: The Hefei facility of Jieseje began operations
