Industry Experts Praise Sunward Xianxinghao Ultra-Large-Diameter Shield Machine
A New Milestone for Full-Face Tunnel Boring Equipment
Sunward Machine has completed the assembly and commissioning of the Xianxinghao ultra-large-diameter shield machine, marking another important step in the company’s development of full-face tunnel boring equipment. With a diameter of 12.12 meters, the machine demonstrates Sunward’s growing capability in large-section shield tunneling, high-end equipment manufacturing, and customized solutions for complex underground engineering projects.
During the same period, senior representatives from the Tunnelling Machinery Branch of the China Construction Machinery Association visited Sunward Machine for an expert review and technical exchange. The visit focused on the company’s production and service capability upgrade, intelligent manufacturing process, product quality system, and preparation work for full-face tunnel boring machine enterprise evaluation.
Expert exchange on Sunward’s full-face TBM manufacturing and service capability upgrade.
The delegation inspected Sunward’s manufacturing base, production workflow, and equipment assembly process.
Expert Recognition for a 12.12m Large-Diameter Shield Machine
During the site visit, the expert team reviewed the R&D design, production manufacturing, assembly, commissioning, and service preparation of Sunward’s 12.12m large-diameter shield machine. They paid close attention to key technical parameters, intelligent configuration, manufacturing precision, and the overall capability required for large-section tunnel excavation.
- Large-section tunneling capability: The 12.12m machine supports high-efficiency excavation for demanding tunnel projects that require large excavation diameters and reliable ground control.
- Full-process manufacturing control: Sunward demonstrated its integrated workflow from design and component production to final assembly and commissioning.
- Service system improvement: The review also covered technical documentation, after-sales support, quality management, and evaluation preparation.
The expert recognition reflects Sunward’s progress as a China shield machine manufacturer serving both domestic and overseas underground infrastructure markets.
Strengthening Production, Service, and Innovation Capabilities
In the technical meeting, Sunward Machine reported its preparation for the production and service capability evaluation of full-face tunnel boring machine enterprises. The report covered system construction, technical data organization, innovation achievements, service process improvement, and quality control measures.
The association experts provided professional feedback from an industry perspective. They recognized Sunward’s achievements in independent innovation, R&D investment, intellectual property, manufacturing capability, and overseas market expansion, while also offering targeted suggestions for documentation optimization and evaluation preparation.
For tunneling equipment users, these improvements are more than internal management upgrades. A stronger production and service system helps ensure more reliable machine delivery, better technical support during construction, and improved lifecycle service for underground engineering projects.
From Manufacturing Base to Global Project Support
The rollout of Xianxinghao is a practical example of Sunward’s continued investment in advanced shield machine technology. In large-diameter tunneling, equipment manufacturers must coordinate cutterhead design, main drive reliability, segment assembly systems, slurry or earth pressure balance control, intelligent monitoring, and site service planning. Each of these factors can influence excavation stability, construction efficiency, and long-term project performance.
Sunward Machine stated that it will absorb the expert guidance, continue improving its technical system, and further strengthen core competitiveness through R&D innovation and quality management. The company will also support industry association work in technical standards and quality standards, contributing to standardized, healthy, and sustainable development of China’s tunneling machinery sector.
Reliable Shield Machines for Modern Underground Engineering
As a professional tunnel boring machine manufacturer, Sunward provides customized shield machines, pipe jacking machines, and underground construction equipment for metro, railway, municipal, water conservancy, mining, and urban underground space projects.
