Founded in 1986, Shanghai Chunxu Group was formerly known as the No. 3 Model Factory of Xiangshan County, Zhejiang Province. It specialized in manufacturing metal casting molds at the beginning. It served with Shanghai Aerospace Design Institute, Shanghai Aircraft Manufacturing Plant, Shanghai Diesel Engine Co., Ltd., Shanghai Jiangnan Shipbuilding Co., Ltd. Large-scale state-owned enterprises such as the joint stock company and the Shanghai Heavy Machinery Plant provide aircraft wing drawing dies, diesel engine cylinder dies, marine propeller dies, aerospace, and shipbuilding equipment.

　　In 1989, the factory moved to Shanghai. In 1999, it was renamed Shanghai Chunxu Mould Industry Co., Ltd.

　　In 1991, Chunxu began to cooperate with Shanghai Aircraft Manufacturing Plant and Boeing and McDonnell Douglas in the development of aircraft wing projects. In 1999, the Shanghai Aircraft Manufacturing Plant introduced the American helicopter project, the model LE100, and the introduction of the heavy-duty machine rotomolding fuel tank. At that time, the rotary plastic helicopter fuel tank was expensive. The Shanghai Aircraft Factory decided to localize in China, but after three months of research and search nationwide, it did not find a manufacturer that can produce rotational molding molds. At this difficult time, the founder of the company, Mr. Huang Quanchun, took the initiative to ask, Shanghai Aircraft Manufacturing Factory readily accepted the project to Shanghai Chunxu, which has a certain mold casting foundation, and hoped to rely on the strength of the Chinese people to independently develop this new project. In August 1999, the first mold of the rotomolding helicopter fuel tank began to start, but it quickly encountered difficulties and the first trial production failed. After the founder, Mr. Huang Quanchun led the technicians to study and inspect the relevant enterprises all over the country, and repeatedly visited Beijing, Guangzhou, Shenyang and other places to visit large machinery and mold manufacturers to discuss the manufacture of aluminum alloy molds. Working with Boeing of the United States to study mold surface problems and manufacturing technology improvements for zinc alloy and aluminum alloy casting. After groping, researching, and trial production, after three months, I successively reported three pairs of molds, and finally succeeded in trial production in March 2000. This pair of molds also marked the birth of the first aluminum alloy rotomolding mold in China. The blank history of China's rotomolding aluminum alloy molds. In the following years, through its own exploration and innovation, Shanghai Chunxu took the lead in completing the professionalization of the design and processing of rotomolding aluminum alloy molds in China, and became one of the earliest and most powerful professional mold manufacturers in China.

　　In the initial stage, due to insufficient equipment and shortage of technicians, and facing the competitive pressure of foreign advanced technology, China's rotomolding molds cannot be recognized by the international rotomolding industry. Even Taiwan's rotomolding molds rely on imports from the US and Italy. Mr. Huang Quanchun, the founder of the company, is committed to changing this situation. In order to cooperate with Longcheng Group, the most famous rotomolding toy manufacturer in Taiwan, he promised to help him develop a set of molds for free, when the first pair of rocking chair molds are perfectly presented. This was recognized by the top management of Longcheng and opened the road of rotational molding cooperation. In the next two years in 2000, Shanghai Chunxu developed and manufactured more than 80 sets of rotomolding molds for Longcheng, which really dispelled the concerns of the international market for Chinese molds. Later, Mr. Huang Quanchun led technicians to the United States, Europe, and Australia and other rotational molding technology developed countries to study and exchange, so that Shanghai Chunxu rotational molding mold manufacturing technology has been greatly improved, mold quality has also rapidly improved.

　　After years of development, today's Shanghai Chunxu has developed into a subsidiary with Shanghai Chunxu Mould Industry Co., Ltd., Shanghai Chunyang Rotomolding Products Co., Ltd. and Lianyungang Chunxu Rotational Molding Technology Co., Ltd. with a total registered capital of 53.8 million. It has a total area of ​​85,000 square meters, a construction area of ​​60,000 square meters, a total investment of 150 million yuan, and a large-scale rotomolding enterprise with more than 380 employees. The products involve sewage treatment and environmental protection industry, all plastic rotomolding storage tanks, water treatment containers, chemical industry tanks. Body, sewage treatment tank, septic tank, inspection well and other industries, the company's products are mainly exported to Europe, the Middle East, Japan, South Korea, North America and other countries and regions, in the 2008 Beijing Olympic Games, 2010 Madrid World Expo, 2012 London Olympic Games, The company also participated in the design and construction of sports facilities as a designated rotomolding mold manufacturer.

　　The company's leaders and all employees, led by Mr. Huang Quanchun, the chairman of the board, work together to create an internationalized Chunxu with more products, better quality, better service and partners from all over the world. Plastic new era! We sincerely welcome friends from all walks of life to visit our company and negotiate business!
