In the rapidly evolving landscape of global transportation, the demand for precision steel casting railway components has reached an all-time high. As a premier supplier and manufacturer, JUNLONG Machinery Co., Ltd. stands at the intersection of traditional craftsmanship and "Industry 4.0" technological integration. We specialize in producing safety-critical components that withstand extreme fatigue, high-load stresses, and diverse environmental conditions.
Established Foundation in Shandong
Total Production Area
Annual Casting Capacity
JUNLONG Machinery Co., Ltd. was founded in 2014. Located in Weifang, Shandong, the company covers a total area of 60,000 square meters and has an annual production capacity of 20,000 tons of precision castings and machined finished parts. It 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.
Our commitment to E-E-A-T principles is reflected in our ISO 9001, TS 16949, and UL certifications, ensuring that every railway component—from bogie frames to braking systems—meets international safety standards.
We utilize ProCAST and MagmaSoft for solidification simulation, predicting potential defects before the mold is even created. This ensures a 99.8% first-pass yield for complex railway castings.
Integrating 3D-printed sand molds and wax patterns for rapid prototyping. This reduces the development cycle for new railway components from months to weeks, catering to urgent maintenance and repair needs.
Our future roadmap includes real-time spectrometer data integration with AI to automatically adjust alloy composition, ensuring consistent mechanical properties across different production batches.
Located in the heart of China's industrial manufacturing hub, our facility leverages a sophisticated ecosystem of raw material suppliers and logistics networks. Our "Factory 4.0" initiative integrates automated wax injection, robotic dipping, and controlled environment drying rooms to eliminate human error.
For global enterprises, this means supply chain resilience. We maintain a strategic buffer of high-grade alloy steel and carbon steel to mitigate global market fluctuations. Our proximity to major shipping ports in Qingdao ensures that "China Precision Castings" reach Europe, America, and Southeast Asia with minimal lead time.
We provide comprehensive casting solutions for various railway sectors:
Focus on lightweight aluminum and high-tensile alloy steel components to reduce unsprung mass and improve energy efficiency at speeds over 300km/h.
Casting solutions for coupler systems, bogie bolsters, and side frames designed to endure 30-ton axle loads in extreme mining environments.
Precision hardware for braking systems and track infrastructure that require high corrosion resistance and low maintenance cycles.
Railway safety is non-negotiable. JUNLONG Machinery operates under a rigorous quality management system. We don't just "cast metal"; we engineer trust.
Our team of 30+ engineers provides DFM (Design for Manufacturing) feedback, helping you optimize part weight and casting feasibility during the RFQ stage.
We work with international standards including ASTM (USA), DIN (Germany), JIS (Japan), and EN (Europe) to ensure direct compatibility with your existing designs.
Dedicated account managers for North America and Europe provide 24-hour response times, addressing logistics, customs clearance, and technical queries.
Core Advantages: Seamless connection, controllable quality, shorter lead times. From initial design concepts to final product delivery, all key processes are completed in-house:
1. Mold Manufacturing: Ensures dimensional accuracy at the source of casting.
2. Precision Casting: Using internationally advanced automated casting production facilities.
3. Machining: Equipped with horizontal/vertical machining centers, CNC lathes, and grinders.
4. Surface Treatment: Meets final appearance and performance requirements such as painting, powder coating, or galvanizing.
