Founded in 2014 and headquartered in Weifang, Shandong, JUNLONG Machinery Co., Ltd. has evolved from a local foundry into a global benchmark for precision carbon steel fabrication. Spanning 60,000 square meters, our facility represents the pinnacle of "Industry 4.0" integration in the casting sector.
With an annual capacity of 20,000 tons of precision castings and finished machined parts, we specialize in high-integrity components crafted from carbon steel, alloy steel, and stainless steel. Our workforce of 200+ professionals includes a dedicated core of 30+ senior engineers, ensuring every project benefits from deep technical expertise.
In the contemporary industrial ecosystem, carbon steel remains the "backbone of infrastructure." Global procurement trends indicate a significant shift towards Total Cost of Ownership (TCO) optimization. Enterprises in North America and Europe are no longer just seeking "parts"; they are seeking "strategic fabrication partners" who can offer Information Gain—insights into weight reduction, material substitution, and longevity.
High-strength carbon steel castings are critical for chassis components and engine brackets where durability meets mass-production efficiency.
From wind turbine components to solar tracking gear, carbon steel provides the necessary fatigue resistance for 25-year life cycles.
Safety-critical components for high-speed rail systems require ISO 9001 and TS 16949 certified manufacturing processes.
Our facility is equipped with internationally advanced automated casting production lines. We utilize Lost Wax Investment Casting technology to achieve tight tolerances and superior surface finishes that reduce or eliminate the need for secondary machining.
In-house mold manufacturing ensures dimensional accuracy at the source, significantly shortening lead times for custom prototypes.
Equipped with horizontal/vertical machining centers and CNC lathes for high-precision finishing requirements.
Comprehensive options including powder coating, galvanizing, and heat treatment to enhance mechanical properties.
Trust is built on verification. JUNLONG Machinery maintains a rigorous quality management system to ensure global reliability.
Our certifications include ISO 9001, IATF 16949 (Automotive), and UL (Safety Standards), ensuring full process control over every production detail.
We provide high-quality products, services, and solutions to global industry leaders and mid-to-high-end clients in Europe and America. Our components are vital for:
As we move towards 2025, JUNLONG is integrating AI-assisted simulation for solidification analysis. This allows us to predict potential casting defects before the first drop of metal is poured. By combining digital twins of our molds with automated chemical spectral analysis, we are setting a new standard for "Zero-Defect" manufacturing in the carbon steel fabrication industry.
