Founded in 2014 and headquartered in the industrial heart of Weifang, Shandong, JUNLONG Machinery Co., Ltd. has evolved into a tier-1 global supplier for OEM Mining Machinery Casting. Spanning 60,000 square meters, our facility represents the pinnacle of China's "Intelligent Manufacturing 2025" vision, combining traditional metallurgical expertise with AI-driven process controls.
With an annual production capacity of 20,000 tons of precision castings and machined finished parts, we specialize in high-stress materials including carbon steel, alloy steel, and stainless steel. Our team of 200+ dedicated professionals, including over 30 senior engineering technicians, ensures that every component meets the rigorous demands of the global mining sector.
In the modern mining landscape, the transition from surface mining to deeper, more complex underground operations has increased the failure stress on machinery components by over 40%. As a leading OEM Mining Machinery Casting Supplier, JUNLONG Machinery employs a multi-phase technical roadmap to ensure component longevity and reliability.
Utilizing ProCAST and MagmaSoft simulation, we predict shrinkage porosity and thermal stresses before the first drop of metal is poured, reducing lead times by 30%.
Developing custom alloy steel grades that offer superior fracture toughness (K1c) and abrasion resistance for drill bits and crusher liners.
Integration of multi-axis CNC machining centers (horizontal and vertical) to achieve tolerances within +/- 0.01mm for critical assembly components.
Our castings are engineered to perform in the world's most hostile environments, from the sub-zero temperatures of Canadian oil sands to the abrasive dust of Australian iron ore mines.
Our ESP Cross Coupling Cable Protectors and petroleum cable clamps are critical for protecting electrical submersible pump lines in offshore rigs, designed to withstand high pressure and corrosive saltwater environments.
Precision castings for agricultural machinery, such as harvester hubs and transmission housings, provide the durability needed for 24/7 seasonal operations across the Midwest US and European plains.
Supplying high-precision truck valve parts and brake lever components for heavy-duty commercial vehicles used in massive infrastructure projects in Southeast Asia and the Middle East.
As a prominent China Casting Manufacturer, we leverage the unparalleled industrial ecosystem of the Shandong province. This geographic advantage allows us to integrate the entire value chain—from raw material sourcing (premium scrap and ferroalloys) to advanced surface treatment—within a 100km radius.
Quality is not an option; it is our foundation. We adhere to the strictest international standards to ensure reliability in every ton of metal we pour.
Rigorous quality management systems covering the entire production lifecycle, ensuring consistent output for mid-to-high-end global clients.
Automotive-grade precision and reliability standards applied to our mining machinery casting processes for defect-free performance.
Full physical and chemical analysis, including spectral analysis, tensile testing, and non-destructive testing (NDT).
