Dongguan Tuozhan Industrial Co., Ltd. was established in August 2000, located in Tanghuanling Industrial Zone, Chashan Town, Dongguan City, Guangdong Province. It is an environmentally friendly private technology enterprise that integrates scientific research and development, production, and sales, specializing in the recycling and utilization of renewable resources. The company currently has nearly 400 employees, with a strong technical force and excellent production equipment, including advanced automated production lines and high-precision raw material and product testing instruments domestically. The company always emphasizes internal management, adhering to the corporate spirit of "pragmatism, dedication, standardization, and innovation," strictly abiding by the business philosophy of "producing world-standard products and building world-renowned enterprises," and implementing a development strategy of "three-in-one to meet standards." It increases efforts in technological development, strengthens talent aggregation, and enhances corporate culture construction. In 2006 and 2008, Tuozhan received financial support from the Guangdong Provincial Small and Medium-sized Enterprise Technical Project Renovation Program and the Dongguan Municipal Major Technical Renovation Program for Small and Medium-sized Enterprises, respectively. Through these two rounds of technological renovation, production energy consumption was reduced, saving a significant amount of electrical resources and lowering production costs. The method of "Producing Two and Three-dimensional Hollow Fibers Using Recycled Plastics" invented by Tuozhan was applied for a national patent in 2007. Upholding the business tenet of "integrity, service, cooperation, and win-win," since 2000, the company has been annually rated as a "Contract-abiding and Credit-worthy Enterprise" in Dongguan. Since 2008, it has consecutively been awarded the title of "Guangdong Integrity Demonstration Enterprise" by the Guangdong Entrepreneurs Association and the Entrepreneurs Federation.
