Top performance casting components optimized for agriculture, automotive, and flow control applications.
JUNLONG Machinery Co., Ltd. was established in 2014 in Weifang, Shandong, China. Over the past decade, we have expanded to become an elite precision casting supplier utilizing advanced lost wax investment casting processes.
Spanning 60,000 square meters, our facility delivers an annual production capacity of 20,000 tons of precision castings and CNC finished parts. Our metallurgical focus encompasses carbon steel, alloy steel, and stainless steel, ensuring custom solutions for high-performance applications.
Driven by a team of over 200 dedicated professionals, including 30+ highly-experienced metallurgical and mechanical engineers, we integrate casting, CNC machining, heat treatment, and surface finishing under one roof.
Download Technical Specification CatalogMetallurgical depth engineered for performance under abrasive soils, heavy loads, and severe shock impact.
Agricultural equipment operates in highly abrasive soils and rocks. We customize chemistry by adjusting levels of carbon, manganese, chromium, nickel, and molybdenum to maximize toughness and abrasion resistance.
Our precise tempering, normalizing, and quenching operations eliminate internal stresses. This optimizes grain structures to achieve the required hardness profiles (up to 45-50 HRC) and prevent field failures.
Through simulation software like MAGMAsoft, we predict shrinkage cavities and optimize gating systems. This guarantees void-free internal structures, minimizing tool damage during precision machining.
Bridging Chinese manufacturing efficiency with global standards of engineering excellence.
Equipped with internationally advanced automated casting production lines. We utilize physical and chemical testing setups to verify material mechanical properties under high-stress conditions.
With products successfully exported to Germany, the United States, Italy, Canada, and beyond, our engineering and quality systems comply fully with global client standards.
Serving automotive, rail transportation, petroleum machinery, agricultural engineering, and material handling (e.g., custom forklift parts) with precision OEM casting services.
Many foundries only supply rough castings, forcing you to source secondary machining vendors. JUNLONG offers a fully integrated workflow: mold design, investment casting, heat treatment, precise CNC machining, and final surface coating.
Precision CNC Workshop: Equipped with advanced horizontal and vertical machining centers, CNC lathes, milling machines, and grinders. We achieve tolerances as tight as ±0.01mm, ensuring your parts assemble seamlessly on the production line.
Customer Value: Consolidating your supply chain under a single manufacturer eliminates logistical delays, communication errors, and multiple-tier quality disputes.
By adopting automated wax injection, automated shell-making lines, and environment-controlled drying rooms, we ensure dimensional consistency batch after batch. This modern infrastructure allows us to scale production while containing costs.
Environmental & Regulatory Compliance: Operating a clean, modern foundry is a critical risk mitigation factor. Our plant features state-of-the-art dust extraction, emissions monitoring, and waste treatment equipment, ensuring uninterrupted operations.
Raw Material Supply Partnerships: Located in Weifang, Shandong—a major industrial manufacturing hub—we maintain strategic partnerships with steel and alloy suppliers to buffer against market volatility and guarantee steady lead times.
Precision-cast parts customized to meet the strict demands of diverse industries.
Wear-resistant tillage points, brackets, combine harvester hinges, shear hubs, and custom seed drill components designed for continuous duty cycles.
High-strength cable protectors, downhole tool components, valve housing assemblies, and fluid handling castings certified to survive under high pressures.
Drivetrain components, transmission brackets, steering knuckles, and brake components cast under strict quality management systems (IATF 16949).
High-load linkages, excavator bucket teeth mounts, forklift chassis pivots, and suspension brackets built to withstand extreme mechanical forces.
We apply process controls at every step of production. Our lab is equipped for comprehensive mechanical and chemical analysis, including spectrometers, tensile testers, hardness testers, and non-destructive testing (NDT).
Full Quality Traceability: From raw steel chemistry checks to final dimensional inspections, every batch is fully documented. Our strict record-keeping ensures complete visibility for high-integrity industries.
Audited manufacturing systems verifying trace performance metrics for international markets.
Aligning with tomorrow’s agricultural designs: high wear resistance, lightweight geometries, and sustainable manufacturing.
Next-generation agricultural machinery demands lighter, stronger parts to lower fuel consumption and handle higher working speeds. JUNLONG's technical roadmap focus areas include:
Our commitment to modernization ensures that OEM clients receive field-tested, highly precise cast components designed to lower their total cost of ownership.
