Founded in 2014 and headquartered in Weifang, Shandong, JUNLONG Machinery Co., Ltd. has emerged as a global benchmark in the investment casting industry. Spanning 60,000 square meters, our facility integrates high-capacity manufacturing with surgical precision. We specialize in safety-critical heavy-duty railway components, automotive parts, and engineering machinery, delivering over 20,000 tons of finished parts annually.
Our commitment to E-E-A-T (Experience, Expertise, Authoritativeness, and Trustworthiness) is evidenced by our 200+ dedicated staff and 30+ senior engineers who oversee every metallurgical detail from CAD design to final non-destructive testing.
The global rail industry is undergoing a paradigm shift toward "Heavy Haul & High Speed." This evolution demands components that can withstand extreme fatigue, varying thermal gradients, and immense axial loads. Investment casting (Lost Wax Casting) has become the preferred manufacturing route for complex railway geometries such as couplers, bogie brackets, brake disks, and suspension components.
Decarbonization in rail logistics is driving the need for lightweight yet high-strength alloy steels. We utilize advanced metallurgical simulation to reduce component weight by up to 15% without compromising structural integrity.
Global Tier-1 buyers now mandate ISO 9001 and IATF 16949 certifications. JUNLONG provides full material traceability and 3.1 certification for all heavy-duty rail components.
Our "One-Stop Integrated Manufacturing" covers mold design, precision casting, CNC machining, and heat treatment, reducing supply chain complexity for international OEMs.
The future of railway casting lies in Digital Twin Integration and AI-Optimized Alloy Development. By 2025, JUNLONG is committed to implementing real-time sensor feedback within the casting process to detect micro-porosity at the molecular level.
We have secured ISO 9001, TS 16949, and UL certifications. These are not just badges; they are our promise of process control and continuous improvement.
Equipped with internationally advanced automated facilities, we ensure product quality stability for high-tech industries like rail and petroleum.
While we lead in Rail Transportation, our precision castings are structural backbones for multiple high-load industries:
