In the rapidly evolving global rail landscape, procurement is no longer just about cost; it’s about Information Gain and Operational Resilience. As a premier China Steel cast railway components manufacturer, JUNLONG Machinery Co., Ltd. (Founded in 2014) has redefined the standards of precision investment casting. With 60,000 square meters of high-tech production space in Shandong, we bridge the gap between traditional heavy casting and modern aerospace-grade precision.
The global railway industry is shifting towards high-speed, heavy-haul, and green logistics. This requires components—from bogie supports to coupler systems—that offer superior fatigue resistance and weight optimization. Our mission is to provide the "mechanical backbone" for the world's most demanding rail networks, ensuring safety and durability through advanced materials like carbon steel, low-alloy steel, and austenitic stainless steel.
Utilizing internationally advanced automated casting lines, we ensure product quality stability. Our physical and chemical analysis labs provide real-time monitoring of mechanical properties for every heat of steel.
Our products are trusted in the most regulated markets, including Germany, the United States, Italy, and Canada. We understand the specific nuances of AAR (American Association of Railroads) and UIC standards.
Holding ISO 9001, TS 16949, and UL certifications, we offer full-process quality traceability. This ensures that every component used in rail transportation meets life-critical safety requirements.
Shandong Province is the heart of China’s casting industry. Being located here grants us access to a complete raw material ecosystem, specialized logistics, and a highly skilled workforce, allowing us to maintain competitive lead times without sacrificing precision.
We don't just cast; we engineer. From mold design (Tooling) to CNC Machining and Surface Treatment (Zinc plating, Powder coating, E-coating), the entire lifecycle happens in-house. This eliminates multi-vendor communication risks.
We provide localized documentation support for European and North American clients, including REACH/RoHS compliance, Material Test Reports (MTRs), and EN 10204 3.1 certification. Our engineering team speaks the language of global standards.
JUNLONG Machinery Co., Ltd. specializes in materials such as carbon steel, alloy steel, and stainless steel. With over 200 employees, including more than 30 engineering technicians, the company is a high-quality casting supplier integrating precision casting and deep processing. We serve as a key supplier of high-tech precision castings for industries such as automotive, rail transportation, engineering machinery, and petroleum machinery.
The push for energy efficiency in Europe and Asia is driving demand for lightweight alloy steel castings. Our lost wax process allows for thinner wall thicknesses and complex geometries that traditional sand casting cannot achieve, reducing the unsprung mass of bogies.
In North American heavy-haul freight, coupler systems and wedge castings face extreme cyclical loading. Our proprietary heat treatment processes enhance the impact toughness of alloy steel components, extending the service life in harsh, freezing climates.
Global enterprises are now auditing for "Green Supply Chains." JUNLONG is investing in waste-wax recycling and dust suppression systems, aligning with the Carbon Neutrality goals of our Tier-1 partners in the EU and USA.
