In the modern era of Precision Agriculture, the reliability of farm equipment is no longer just about durability; it's about geometrical precision and material integrity. As a leading China Farm Equipment Precision Cast Parts Supplier, JUNLONG Machinery Co., Ltd. understands that a single component failure in a harvester or a seeder can lead to catastrophic downtime during critical planting or harvesting windows.
Precision casting, particularly the investment casting (lost wax) process, has become the backbone of high-performance agricultural machinery. By utilizing advanced carbon steel, alloy steel, and stainless steel, we provide components that withstand the extreme abrasive conditions of soil interaction and the high-torque demands of modern tractor drivetrains.
Equipped with internationally advanced automated production facilities, we enhance manufacturing efficiency and product quality stability while meeting rigorous testing for mechanical properties.
Exporting to Germany, the USA, Italy, and Canada, we serve global industry leaders with high-precision castings that meet E.U. and American industrial standards.
With ISO 9001 and TS 16949 certifications, every batch undergoes chemical analysis and physical testing to ensure 100% reliability in the field.
Custom-cast points, shanks, and plow shares made from high-manganese steel. These parts are engineered for high impact and wear resistance in rocky or compacted soil environments found across North America and Australia.
Precision-cast components for harvester grain handling and threshing systems. Tight tolerances ensure seamless integration with sensor-based automated sorting equipment.
High-pressure hydraulic fittings and valve bodies for tractors and sprayers. Our precision casting eliminates internal porosity, preventing leaks under the high-stress cycles of precision irrigation.
Stainless steel precision parts for automated feeding and milking systems, where corrosion resistance and hygiene are paramount for localized compliance.
Located in Weifang, Shandong—a global hub for machinery manufacturing—our factory benefits from a dense ecosystem of raw material suppliers and logistics experts. This proximity allows for:
By controlling the full industrial chain, we eliminate the communication costs and quality risks associated with multi-vendor sub-contracting.
We are integrating AI-assisted topology optimization to reduce part weight without sacrificing strength, crucial for the next generation of electric farm machinery.
Combining 3D-printed sand molds with traditional precision casting to offer rapid prototyping for custom farm equipment designs within days, not weeks.
Research into self-lubricating alloy castings for pivots and joints to reduce maintenance requirements in autonomous, unmanned farming vehicles.
JUNLONG Machinery Co., Ltd. was founded in 2014 in Weifang, Shandong. Spanning 60,000 square meters, we have built a reputation as a high-quality casting supplier integrating precision casting and deep processing. With over 200 employees, including 30+ senior engineering technicians, we are more than just a manufacturer; we are your strategic partner in precision manufacturing.
Our facilities include internationally advanced automated casting lines and a comprehensive physical and chemical analysis laboratory. Whether it is carbon steel, alloy steel, or stainless steel, our annual output of 20,000 tons ensures we can scale with your business growth.
Ensuring process control over every production detail to achieve high customer satisfaction and meet international trade standards.
For high-impact parts like plow shares, Alloy Steel or High Manganese Steel is preferred. For corrosive environments like fertilizer spreaders, 304/316 Stainless Steel is ideal. We provide expert material consultation based on your specific application.
We use the Lost Wax Investment Casting process combined with CNC machining. This allows us to achieve tight tolerances that are impossible with traditional sand casting, reducing your assembly time and ensuring perfect fitment.
Usually, mold design and sampling take 3-4 weeks. Once approved, mass production takes 4-6 weeks depending on volume and secondary machining requirements. Our integrated chain in Weifang helps us beat global averages by 15-20%.
Yes. We offer professional surface treatments including zinc plating, powder coating, painting, and electrophoresis (E-coating) to ensure parts withstand years of exposure to sun, rain, and soil moisture.
While our capacity is 20,000 tons, we have a dedicated engineering team for R&D and small-batch production to help global OEMs validate new designs before scaling to mass production.
Absolutely. We are ISO 9001 and TS 16949 certified. Our parts meet ASTM (USA), DIN (Germany), and JIS (Japan) standards, ensuring they are ready for global distribution.
