For years, we have remained the only enterprise in China’s rotomolding industry that maintains long-term cooperation and exchanges with universities and industry associations at home and abroad, setting us apart from our peers in the domestic market.

Around 2013, we realized that equipment and mold manufacturing alone were not enough. The key to mutual success lies in providing customers with comprehensive solutions to optimize their product design and production lines. Since then, our company has transformed its positioning from a manufacturer to a service-oriented enterprise, dedicated to delivering end-to-end system solutions.

 I officially joined Rising Sun Rotomolding in 2015, marking the start of our close integration with the global rotomolding community. We actively participate in industry associations worldwide, attend international rotomolding conferences, and represent the China Rotomolding Association in overseas speeches. Over the past decade, we have expanded our sales network significantly—from having offices only in China to establishing a presence in Australia and even purchasing land in the United States, enabling us to serve customers more closely with high-quality, localized support.

To date, our products have been exported to more than 90 countries globally. Notably, our very first piece of equipment was sold overseas. Despite my father’s limited English proficiency and reserved personality, his sincerity and perseverance won the trust of customers step by step.
