Engineered for Durability in Extreme Industrial and Agricultural Environments
In the contemporary landscape of global industrial manufacturing, 16Mn (Q345B) has emerged as the gold standard for high-stress agricultural machinery components. As an OEM 16Mn precision casting agricultural machinery parts manufacturer, we recognize that the shift toward precision farming requires components that can withstand higher mechanical loads while maintaining lightweight profiles. 16Mn steel, characterized by its low-carbon alloy content, offers a superior strength-to-weight ratio, excellent weldability, and low-temperature impact toughness—essential for farm machinery operating in diverse climates from the Siberian plains to the tropical zones of Southeast Asia.
The global demand for precision-cast agricultural parts is currently driven by the "Smart Farming" revolution. OEMs in North America and Europe are increasingly outsourcing to specialized factories in China to leverage advanced investment casting (lost wax) technologies that achieve dimensional tolerances once reserved for aerospace. This trend is not merely about cost reduction; it is about Information Gain in the manufacturing process—integrating material science with automated production to eliminate sub-surface defects that cause catastrophic field failures.
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. It specializes in materials such as carbon steel, alloy steel, and stainless steel. With over 200 employees, including more than 30 engineering technicians, the company is a high-quality casting supplier integrating precision casting and deep processing.
Leveraging strong engineering capabilities, a complete quality control system, and advanced management systems, the company has become a well-known brand manufacturer in the field of precision casting both domestically and internationally. Its products are exported to overseas markets, including Germany, the United States, Italy, Canada, and other countries.

The transition from sand casting to precision investment casting for agricultural durability.
16Mn (Q345B) provides a yield strength of 345MPa. Our casting process ensures a homogenous microstructure, reducing the risk of fatigue cracks in harvester blades and tillage parts.
Equipped with internationally advanced automated casting production facilities and comprehensive physical and chemical analysis equipment, we enhance product stability and mechanical reliability.
We are equipped with horizontal machining centers, vertical machining centers, CNC lathes, and grinders, providing full-process machining from rough blanks to precision components.
Furthermore, the company has obtained ISO 9001, TS 16949, UL, and other quality management system certifications, ensuring process control over every production detail. We provide high-quality products, services, and solutions to global industry leaders and mid-to-high-end clients in Europe and America.
Our precision castings serve as the backbone for the world's most demanding industries.
Forging Strong Mechanical Backbones. Excavators, loaders, and cranes rely on our high-strength, wear-resistant castings to support heavy-duty operations in harsh mining and road environments.
Providing safety-critical components for rail transportation and automotive systems, ensuring structural integrity at high velocities.
Precision-cast pump and valve accessories made of premium alloy steel, offering corrosion resistance and high-pressure stability.
Custom lost wax casting components for harvesters and farm vehicles, designed for soil-engaging tools that require maximum abrasion resistance.
As we look toward 2030, the integration of AI and IoT into agricultural machinery parts is becoming a reality. Smart sensors require housing that is perfectly cast to protect electronics from vibration and moisture. JUNLONG Machinery is at the forefront of this transition, offering "Design for Manufacturability" (DFM) support to global clients.
We provide localized technical support and ensure all products meet regional environmental regulations (REACH/RoHS) and metallurgical standards (ASTM, DIN, JIS). Our logistics network ensures seamless delivery to major hubs in the US, Germany, and beyond.
16Mn (Q345B) is a low-alloy high-strength steel that provides an excellent balance between cost, strength, and weldability. It is significantly more durable than standard carbon steel in high-impact agricultural applications.
Our lost wax process achieves tolerances within ISO 8062 CT4-CT6, significantly reducing or eliminating the need for secondary machining, which saves cost and time for OEM partners.
Yes, we provide a full suite of surface treatments including zinc plating, powder coating, electrophoresis, and shot blasting to ensure longevity in outdoor farming environments.
Every batch undergoes spectral analysis and mechanical testing. We provide full material certificates and dimensional inspection reports with every shipment, ensuring 100% traceability.
