establishes a vertical manufacturing system spanning northern and southern China, with a total production area exceeding 6,500 square meters.
Fifteen years ago, the shareholders of Sanhuan Group made a strategic decision to establish a dedicated foreign trade division in the vibrant port city of Qingdao. What began as a strategic gateway to the global market has, through fifteen years of dedicated cultivation, evolved into an independent, comprehensive high-tech enterprise. Today, Runkel stands as a premier entity integrating Research & Development (R&D), Precision Manufacturing, Global Sales, and Professional Technical Services.
We carry the profound industrial heritage and “Technological DNA” of the Sanhuan Group, blending it with a modern, agile approach to global industrial challenges.
Development
A Synergistic Manufacturing Matrix: Powering Global Supply
Runkel’s competitive edge is anchored in a robust, multi-layered manufacturing and supply chain network. By leveraging Group-wide resources, we have constructed a vertical manufacturing matrix exceeding 6,500 m², strategically positioned to ensure efficient service across both Northern and Southern China:
- Shenyang Enteng Base (3,500 m²):Our hub for large-scale component manufacturing and system integration. This facility specializes in high-complexity projects, including explosion-proof heaters and massive industrial circulation systems.
- Shijiazhuang Sanhuan Base (2,000 m²):A center for high-efficiency and standardized production, focusing on high-watt-density elements and duct heaters to ensure stable supply cycles for large-scale orders.
- Yangzhong Sanhuan Base (1,000 m²):The “Technological Engine” of the enterprise, dedicated to R&D of advanced materials and the precision manufacturing of specialized, ultra-high-voltage heating tubes.
This synergy allows Runke to offer a formidable production capacity and unwavering delivery stability, providing our clients with a reliable foundation for their own operations.
