In the modern era of Agriculture 4.0, the demand for precision-engineered components has skyrocketed. Unlike traditional farming tools, today's agricultural machinery—ranging from autonomous tractors to high-yield harvesters—requires components that offer a perfect balance of lightweight design and extreme durability.
Custom precision casting, particularly using the lost wax (investment) casting method, has become the backbone of this technological shift. By allowing for complex geometries that are impossible through forging or traditional sand casting, precision casting reduces the need for extensive secondary machining, effectively lowering costs while enhancing structural integrity.

Equipped with internationally advanced automated casting production facilities and comprehensive physical and chemical analysis equipment, JUNLONG Machinery significantly enhances manufacturing efficiency and product quality stability while meeting comprehensive testing requirements for the mechanical properties of different materials.
Leveraging strong engineering capabilities, a complete quality control system, and advanced management systems, the company has become a well-known brand manufacturer. Its products are exported to overseas markets, including Germany, the United States, Italy, Canada, and other countries.
We serve as a key supplier for high-tech industries: automotive, rail transportation, engineering machinery, material handling machinery, agricultural machinery, and petroleum machinery. We provide high-quality products, services, and solutions to global industry leaders.
Ensuring longevity in harsh soil and climatic conditions
Ideal for structural components where strength is paramount but cost-efficiency is required. Used extensively in tractor frames and heavy-duty plow mounts.
Incorporating Chromium, Molybdenum, and Nickel to provide superior wear resistance. Essential for components subject to constant friction like thresher teeth and soil cultivators.
Used for fluid control systems in fertilizer sprayers and irrigation valves where corrosion resistance is non-negotiable.
The "China Advantage" in the casting industry has evolved from mere labor-cost savings to Integrated Supply Chain Efficiency. As a leading supplier located in Weifang, Shandong—a global hub for machinery manufacturing—we offer:
Where our precision castings make a difference every day
Gearboxes, tillage tools, harvester blades, and seed drill components that endure 24/7 harvest cycles.
Forging Strong Mechanical Backbones. Excavator buckets, hydraulic cylinders, and crane pivots designed for extreme load-bearing.
Safety-critical components for braking systems and engine mounts that meet TS 16949 standards.
E-E-A-T: Expertise, Experience, Authoritativeness, and Trustworthiness
Our commitment to quality is backed by globally recognized certifications. We don't just cast metal; we engineer reliability.
"The company has obtained ISO 9001, TS 16949, UL, and other quality management system certifications, ensuring process control over every production detail and continuously pursuing and improving product quality to achieve high customer satisfaction."
Addressing the core concerns of global procurement managers
Investment casting (lost wax) provides superior surface finish and dimensional accuracy compared to sand casting. This reduces or eliminates the need for expensive CNC machining, allows for thinner wall sections (reducing weight), and enables the use of high-hardness alloys that are difficult to machine.
We utilize advanced spectral analysis before pouring to ensure the chemical composition is exact. Post-casting, we perform heat treatments (annealing, tempering, quenching) and verify results through tensile strength tests, hardness testing, and impact testing in our certified laboratory.
New projects typically require 3-4 weeks for mold development and sampling. Once approved, mass production usually takes 4-6 weeks depending on volume and machining requirements. Our integrated production line in Shandong allows us to be 15-20% faster than decentralized competitors.
Yes, we offer a full range of surface treatments including zinc plating, powder coating, electrophoresis (E-coating), and hot-dip galvanizing to protect components against fertilizer corrosion and oxidation in humid field conditions.
