Leveraging cross-industry expertise to drive innovations in printing machinery, national infrastructure, tube manufacturing, and global shipping.
With a history of over 30 years, the company's chairman personally oversees its operations. It has participated in the construction of numerous national key projects, and its involvement in high-speed railway projects alone includes the Harbin-Dalian High-Speed Railway, Qingdao-Rongcheng Intercity Railway, Datong-Xi'an High-Speed Railway, Beijing-Shenyang High-Speed Railway, Beijing-Shanghai High-Speed Railway, among others.
Founded in 2014, the company acquired a printing machine manufacturer with a 70-year history in 2020. It produces 100 units of double-sided printing machines of various models annually and is the largest manufacturer of double-sided printing machines in China in terms of sales volume.
Located at the estuary of the Yangtze River, the company covers a land area of 160,000 square meters and provides services for clients/projects including Datang Power, Huaneng Power Plants, and the Hutong Yangtze River Bridge. It also owns two 10,000-ton-class docks with a total value of 200 million yuan (RMB).
It owns 5 10,000-ton-class cargo ships, and continues to invest funds to expand its scale. Its medium-term goal is to have 20 cargo ships for various purposes, with a total tonnage reaching 500,000 DWT (Deadweight Tonnage).
Modern book and periodical publishing houses face unprecedented challenges: shorter run lengths, tighter delivery timelines, and the need for cost-efficient production. Traditional single-sided printing presses require sheets to be run through the machine twice, which increases paper waste, labor costs, and the risk of alignment errors.
Industrial sheet-fed double-sided printing machinery has emerged as the definitive solution. By printing both sides of the sheet in a single pass, publishing houses can effectively double their throughput while maintaining perfect registration. This technology is vital for the mass production of academic textbooks, trade paperbacks, and high-circulation magazines.
The integration of IoT (Internet of Things) and AI-driven quality monitoring systems is transforming the print floor. Modern print machinery for book publishing now features automated ink key adjustments, real-time color density scanners, and self-diagnostic software that prevents downtime.
Simultaneously, environmental regulations are pushing manufacturers to optimize energy consumption and reduce chemical waste. Modern press designs incorporate eco-friendly dampening systems, efficient UV LED curing, and optimized paper path layouts that minimize setup waste, aligning with global green publishing standards.
The technical team has maintained close cooperation with domestic universities and colleges. Adhering to the combination of independent innovation and technology introduction, the team has made over 600 improvements to its products in various aspects. Compared with five years ago, the products have achieved a qualitative leap in all aspects.
It has the capability to rapidly and systematically initiate the development of multi-color offset printing machines. Our focus remains on high-precision mechanical structures, advanced pneumatic sheet separation, and seamless automation interfaces.
We persist in allocating 5.08% of annual sales revenue as special R&D funds. Our commitment to innovation is the engine driving our global competitiveness in the publication manufacturing sector.
To ensure the absolute stability required for high-speed book printing, our production facilities utilize state-of-the-art metalworking and inspection centers.
It has purchased brand-new high-precision main processing equipment for consecutive years, with its equipment level and processing accuracy leading the industry. All key components are independently processed in-house.
The selected high-grade castings all undergo secondary heat treatment to eliminate internal stress, ensuring the machine maintains its shape without deformation during long-term use.
It possesses domestically advanced processing capabilities for key components of double-sided printing machines, as well as robust quality inspection capabilities.
Our specialized sheet-fed double-sided offset printing machinery is engineered for diverse, demanding production environments.
Educational publishers require high speed combined with absolute consistency. Textbooks often contain intricate charts, diagrams, and fine typography. Our double-sided printing machinery ensures that front-to-back registration is flawless, eliminating any page-through shadows. The robust construction allows for continuous 24/7 operation during peak seasonal printing periods.
Color fidelity and paper handling are critical when printing lifestyle, fashion, and scientific periodicals. Our multi-color double-sided presses deliver vibrant color reproduction on coated stocks. With advanced ink-key control systems, publishers achieve consistent ink density across thousands of copies, minimizing setup times and material waste.
For monochrome literature, maximizing output while minimizing cost per page is the primary objective. Our sheet-fed machines are optimized for quick plate changes and rapid paper size adjustments. This flexibility allows publishing houses to easily switch between different book formats (e.g., A5, B5, royal octavo) without long setup delays.
As publishing models shift toward low inventory and print-on-demand (POD), printing machinery must adapt to shorter print runs. Our offset presses offer fast make-ready times and automated cleaning cycles, enabling cost-effective production even for runs of just a few hundred copies, bridging the gap between offset quality and digital flexibility.
In addition, Ding Bangguo, the company's chairman, also proposed that enterprise management should practice the "Three Minds" – namely the "Mind of Vitality", the "Mind of Diligence" and the "Mind of Belonging". This initiative aims to build China's top brand in double-sided printing machinery manufacturing and enhance employees' sense of happiness. The company adheres to its corporate goal of "customer-centricity, where customer satisfaction is our eternal pursuit", upholds the concept of win-win cooperation, and actively builds Ruyu into a renowned brand of Chinese sheet-fed double-sided printing machinery with the "craftsmanship spirit".
Innovation and integration, honesty and modesty, good learning and success, self-transcendence.
