As the global demand for high-speed rail and heavy-load freight increases, the metallurgical integrity of Heavy Duty Train Parts has become the cornerstone of transportation safety. At JUNLONG Machinery Co., Ltd., we recognize that every casting—from bogie components to coupling systems—must withstand extreme mechanical stress, thermal fluctuations, and environmental corrosion.
Founded in 2014 in Weifang, Shandong, our facility spans 60,000 square meters with an annual output of 20,000 tons. We don't just manufacture parts; we engineer reliability through Information-Gain driven design, ensuring that each component contributes to a longer locomotive lifecycle and reduced downtime.
Leading the shift towards "Smart Casting" in the global rail industry.
Transitioning from traditional carbon steels to high-chrome alloys and nanostructured steels. Our R&D focuses on increasing the strength-to-weight ratio, allowing for higher freight loads without increasing energy consumption.
Utilizing AI-driven simulation for mold flow analysis. This minimizes porosity and internal defects before the first drop of molten metal is poured, achieving a "Right-First-Time" manufacturing rate of 98.5%.
Implementing closed-loop sand reclamation systems and energy-efficient induction furnaces to reduce the carbon footprint of heavy-duty part production, aligning with global ESG standards.
Why Weifang, Shandong is the Hub for Global Railway Components.
Being located in Shandong, we benefit from a mature industrial cluster. This provides immediate access to high-quality raw materials and advanced secondary processing facilities. Our integrated manufacturing—from mold making to CNC machining and surface treatment—allows us to offer lead times 20% shorter than international competitors.
Custom solutions tailored for diverse industrial environments.
Railway parts designed for 30+ ton axle loads. We specialize in wear-resistant couplers and bogie frames that operate in high-dust, abrasive mining environments.
Components requiring extreme dimensional stability and fatigue resistance. Our investment casting process ensures smooth surfaces that minimize aerodynamic noise and vibration.
Utilizing high-grade stainless steel (304/316) for chemical-resistant valves and fittings used in liquid hazardous material transportation.
Equipped with internationally advanced automated casting facilities.
Our "Full Industrial Chain Integrated Manufacturing" ensures that from Mold Manufacturing to Precision Casting, CNC Machining (horizontal/vertical centers), and Surface Treatment, every step is traced. This eliminates communication costs and quality risks associated with outsourcing.
Meeting the stringent regulatory requirements of every region.
Adherence to EN 15085 for railway applications and Eurocode standards for material safety. We provide full documentation for TSI (Technical Specifications for Interoperability) compliance.
Meeting Association of American Railroads (AAR) specifications for cast steel components. Our high-strength alloys are tested for impact toughness at sub-zero temperatures (common in Canada/Northern US).
Expert insights into train part casting and sourcing.
High-Precision Metal Components for Global Industry Leaders.
