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.
We specialize in materials such as carbon steel, alloy steel, and stainless steel. With over 200 employees, including more than 30 engineering technicians, we are a high-quality casting supplier integrating precision casting and deep processing.
🛡️ Quality Assurance: ISO 9001, TS 16949, and UL certified, ensuring meticulous process control for every component.
⚙️ Advanced Manufacturing: Equipped with automated casting lines and comprehensive physical/chemical analysis equipment.
🌍 Global Reach: Exporting to Germany, USA, Italy, Canada, and beyond, serving mid-to-high-end global industrial leaders.
In an era of rapid global population growth, the demand for agricultural efficiency has never been higher. As a leading China agricultural machinery castings factory, we recognize that the durability of a harvester or tractor depends on the integrity of its smallest cast parts. Our solutions focus on increasing the "Mean Time Between Failures" (MTBF) for farm equipment operating in extreme environments.
The global agricultural machinery market is shifting toward autonomous and high-horsepower units. These machines require castings that offer high strength-to-weight ratios. Our precision lost wax process allows for thinner walls with higher structural integrity, reducing fuel consumption in the field.
We implement "Green Foundry" practices, utilizing recycled alloys and energy-efficient induction furnaces. This not only lowers the carbon footprint of your supply chain but also ensures compliance with evolving environmental regulations in Europe and North America.
Smart farming equipment relies on sensors and GPS. Our castings provide the precise mounting brackets and housings required for sensitive electronic integration, ensuring zero-vibration stability for high-tech farm assets.
Our commitment to Information Gain involves sharing our technical trajectory. We are not just pouring metal; we are engineering performance.
| Phase | Focus Area | Technologies Implemented | Expected Outcome |
|---|---|---|---|
| Short Term | Simulation Optimization | MAGMAsoft, ProCAST Flow Analysis | Zero-defect casting through digital solidification modeling. |
| Mid Term | Material Innovation | High-Entropy Alloys & ADI (Austempered Ductile Iron) | Increased wear resistance by 40% for tilling components. |
| Long Term | Smart Foundry | IoT-enabled furnace monitoring & AI Quality Inspections | Full traceability and real-time process correction. |
Understanding the nuances of international trade is what sets us apart as a premier agricultural machinery castings supplier. We provide localized support to bridge the gap between Chinese manufacturing and Western engineering standards.
Our workshop includes horizontal and vertical machining centers, CNC lathes, milling machines, and grinders, providing full-process machining from rough blanks to precision components.
High-wear alloy steel castings for soil-engaging tools like plowshares and disk blades, optimized for high-abrasion resistance.
Cast chassis components and hitch systems designed to withstand cyclic loading and fatigue in large-scale commercial farming.
Corrosion-resistant stainless steel pump housings and valve bodies for long-term water management infrastructure.
Conveyor components and material handling castings for post-harvest processing plants.
China offers a unique combination of large-scale industrial capacity, advanced metallurgical research, and cost-efficiency. Factories like Junlong provide OEM services that integrate mold design, casting, and precision machining under one roof, reducing supply chain complexity.
Typically, carbon steel is used for structural parts, while alloy steel is preferred for components requiring high toughness and wear resistance. Stainless steel is reserved for components exposed to corrosive fertilizers or moisture.
We use lost wax investment casting, which allows for tolerances as tight as CT4-CT6. Every batch undergoes CMM (Coordinate Measuring Machine) inspection to ensure perfect fitment.
For new products, mold manufacturing takes 2-3 weeks, followed by sample approval. Once finalized, mass production typically ranges from 4 to 6 weeks depending on volume and machining requirements.
Yes, all shipments are accompanied by EN 10204 3.1 material certificates, including chemical analysis and mechanical property test results.
Partner with a world-class precision casting supplier. Our team of 30+ engineers is ready to optimize your agricultural machinery components for the next generation of farming.
