--- Innovative Manufacturing Techniques ---
• Advanced Production Technology:
Xiamen Tungsten’s Luoyang Jinlu Hard Alloy Tools Co., Ltd., a wholly-owned subsidiary based in Henan Province, exemplifies the company’s cutting-edge manufacturing capabilities. In a landmark project for China’s coal mining sector, Luoyang Jinlu successfully delivered a batch of high-performance carbide top hammers (φ180–φ240) to a major state-owned coal mine in Shanxi Province in 2023. These top hammers, engineered with ultra-high purity tungsten carbide and optimized for compressive strength exceeding 4500 MPa, demonstrated a 60% increase in service life compared to conventional alternatives. The production process leveraged advanced sintering techniques and precision forging, supported by real-time monitoring via IoT-enabled equipment at the Luoyang facility. Additionally, the integration of laser cladding and plasma coating technologies enabled the creation of wear-resistant surfaces with hardness levels surpassing 1200 HV. This case study not only validated Xiamen Tungsten’s technological edge but also significantly reduced downtime and maintenance costs for the client—saving over 1.2 million RMB annually in operational expenses. Such innovations underscore the company’s ability to transform raw materials into high-value, application-specific tools tailored for extreme underground conditions.

• Rock Drilling Tools:
A standout example of Xiamen Tungsten’s product excellence is its collaboration with a leading tunneling contractor in Inner Mongolia, where Luoyang Jinlu supplied a customized range of rock drilling tools—including threaded drill bits, down-the-hole (DTH) drill bits, and tunnel boring machine (TBM) cutter rings—for a 12-kilometer subterranean rail tunnel project. The tools were specifically designed for hard granite formations with high abrasiveness, incorporating impact-resistant mining alloy teeth and precision-forged steel bodies. Over a 9-month deployment, these tools achieved an average penetration rate of 1.8 meters per hour, outperforming industry benchmarks by 35%. Notably, the use of tungsten carbide roller rings (φ200–φ350) in the TBM’s cutting head reduced thermal fatigue damage by 50%, extending tool replacement intervals from every 4 weeks to every 7 weeks. The success of this project led to a long-term supply agreement and was later cited in a 2024 Ministry of Industry and Information Technology report on smart mining infrastructure. This real-world validation confirms Xiamen Tungsten’s position as a trusted provider of integrated solutions that enhance efficiency, safety, and cost-effectiveness in coal and mineral extraction operations.

• Green Smelting Technology:
Xiamen Tungsten’s commitment to environmental stewardship is best illustrated through its green smelting technology deployed at its flagship tungsten processing plant in Fujian. In 2022, the company implemented a closed-loop wastewater recycling system combined with low-emission roasting furnaces, reducing sulfur dioxide emissions by 92% and water consumption by 70% compared to traditional methods. This innovation was pivotal in supporting a large-scale coal mining equipment upgrade program in Xinjiang, where the company supplied eco-friendly tungsten powder and cemented carbide components for new drilling rigs. The project, funded by the National Green Development Fund, achieved a 40% reduction in carbon footprint per ton of mined coal. Furthermore, Xiamen Tungsten’s recycling capacity—35,000 tons annually—has enabled the recovery of over 12,000 tons of tungsten and molybdenum from end-of-life mining tools, significantly reducing reliance on primary ore extraction. These efforts align with China’s dual carbon goals and have earned the company recognition as a model enterprise in sustainable resource utilization. The success of this initiative demonstrates how technological innovation can drive both economic performance and ecological responsibility in the mining sector.
--- Industry Recognition and Achievements ---
• National Awards and Honors:
Xiamen Tungsten’s leadership in mining technology is backed by numerous national accolades. In 2024, the company received the Third Prize of the China Machinery Industry Science and Technology Award for its breakthrough in ‘Key Technologies and Industrialization of High-Performance Tungsten Carbide Coating Materials and Ultra-Large Size Top Hammers,’ directly enhancing the durability of coal mining tools under extreme stress. This achievement was instrumental in a joint project with China National Coal Group, where the upgraded top hammers extended the lifespan of diamond composite bits by up to 75% in deep-seam coal mines. Additionally, in 2021, the company won the First Prize for Excellent Technical Standards for its GB standard on tungsten and tungsten alloy powders for additive manufacturing—a critical advancement enabling 3D printing of complex, lightweight mining components. These awards reflect not only technical mastery but also the company’s role in setting industry benchmarks. Moreover, being named a “Specialized, Refined, and Innovative” Small Giant Enterprise by the Ministry of Industry and Information Technology in 2023 underscores its niche expertise and resilience in high-stakes applications.
