Founded in 2014 and headquartered in Weifang, Shandong, JUNLONG Machinery Co., Ltd. stands as a titan in the Chinese casting industry. Occupying 60,000 square meters, our facility is not merely a factory; it is a hub of innovation where over 200 dedicated professionals, including 30+ senior engineers, redefine precision manufacturing.
With an annual capacity of 20,000 tons, we specialize in high-complexity components using carbon steel, alloy steel, and stainless steel, ensuring the highest standards of structural integrity for global industry leaders.
Our facilities utilize internationally advanced automated production lines. By integrating physical and chemical analysis equipment, we ensure stability in mechanical performance and dimensional accuracy that meets the strictest aerospace and automotive tolerances.
As a global casting leader, our products serve critical infrastructure and machinery in Germany, the United States, Italy, and Canada. We bridge the gap between Asian manufacturing efficiency and Western quality expectations.
From 3D mold manufacturing and precision investment casting to CNC machining and advanced surface treatments, we offer a "one-stop" solution. This eliminates multi-factory communication risks and slashes lead times by up to 30%.
Certified by ISO 9001, TS 16949, and UL, our quality management system is rigorous. Every production detail is tracked, ensuring full traceability and high customer satisfaction across high-risk industries.
The resilience of a China steel casting factory lies in its ecosystem. At JUNLONG, we leverage Shandong's industrial density to maintain production even during global market fluctuations. Our supply chain is bolstered by:
Specialized components for harvesters and tractors that withstand abrasive soil conditions and high-torque stress.
High-pressure pump valves and drill components designed for corrosion resistance in extreme offshore environments.
TS 16949 compliant safety-critical parts, including chassis components and railway suspension systems.
Excavator bucket teeth and structural brackets that define the "backbone" of modern infrastructure projects.
The Evolution of Steel Casting: We are transitioning from traditional foundry methods to Industry 4.0 integrated manufacturing. This includes:
Investment in state-of-the-art machinery is what separates a world-class factory from a local workshop. Our equipment suite ensures that every carbon steel or stainless steel casting meets the micron-level precision required by modern engineering.
