Leading the market in high-strength investment casting for heavy-duty applications.
The Evolution of Agricultural Machinery Investment Casting in the Era of Precision Farming
The global agricultural machinery market is shifting towards high-efficiency, autonomous systems. Investment casting (lost wax process) is at the forefront of this transition, enabling the production of complex, lightweight components that traditional sand casting cannot achieve. Modern tractors and harvesters require parts with higher fatigue resistance to survive 24/7 harvest cycles.
OEMs in the US, Germany, and Italy are increasingly prioritizing "Total Cost of Ownership" (TCO). This includes not just the piece price, but the durability of the component and the reduction in secondary machining. Our factory addresses this by providing near-net-shape castings that reduce waste by up to 30%.
China's casting industry has evolved from labor-intensive to tech-driven. At JUNLONG, we integrate automated wax injection, robotic shell building, and real-time spectroscopic analysis. This ensures that every batch of carbon steel, alloy steel, or stainless steel meets international standards like ISO 9001 and TS 16949.
In a post-pandemic industrial landscape, the resilience of the supply chain is paramount. Chinese manufacturers have optimized the vertical integration of the "Mold Design - Casting - Machining - Surface Treatment" cycle. This eliminates the risks associated with multi-vendor coordination. Our facility in Weifang, Shandong, covers 60,000 square meters, ensuring we have the scale to buffer against global demand surges while maintaining an annual capacity of 20,000 tons.

Founded in 2014, JUNLONG Machinery Co., Ltd. has emerged as a high-quality casting supplier integrating precision casting and deep processing. With over 200 employees, including 30+ engineering technicians, we provide high-tech precision castings for sectors including automotive, rail transportation, construction machinery, and agricultural equipment.
Our commitment to quality is backed by ISO 9001, TS 16949, and UL certifications, ensuring every production detail is monitored for high customer satisfaction across Germany, the USA, Italy, and Canada.
From Material Selection to Extreme Performance
We specialize in carbon steel (AISI 1020, 1045), alloy steel (4140, 8620), and stainless steel (304, 316). Our metallurgical lab ensures optimal grain structure for high-stress agricultural applications.
Using internationally advanced automated production facilities, we significantly enhance dimensional accuracy (CT4-CT6) and surface finish (Ra 3.2-6.3).
Whether it's drought-resistant irrigation components for Australia or high-torque harvester gears for the American Midwest, our parts are designed for specific environmental stress factors.
Full-process quality control from mold manufacturing to final surface treatment. Each part is traceable via heat number and batch code.
Forging Strong Mechanical Backbones. Excavators, loaders, and cranes rely on our high-strength, wear-resistant castings to support heavy-duty operations in extreme mining and road construction environments.
Supplying critical components for harvesters, tractors, and farm vehicles. Our lost wax casting technology ensures complex geometries and thin-walled parts meet the rigors of modern farming.
Precision valve bodies and pump components designed to withstand high pressure and corrosive fluids. Our stainless steel castings provide the longevity required for the oil and gas sector.
Investment casting allows for intricate designs that reduce part weight while maintaining structural integrity. This is vital for fuel efficiency and reducing soil compaction in modern tractors. Additionally, it minimizes the need for machining, significantly lowering production costs for complex parts like brackets and levers.
We utilize controlled heat treatment processes and rigorous physical/chemical analysis. Every melt is tested using spectrometers to verify material composition, and mechanical properties (tensile strength, yield, elongation) are validated in our in-house lab before shipping.
Yes, we have deep experience working with European and American industry leaders. We provide full industrial chain integrated manufacturing, from mold design (CAD/CAM) to machining (CNC centers) and surface finishes like zinc plating, powder coating, or electrophoresis.
Depending on the complexity, mold manufacturing typically takes 3-4 weeks, followed by sample approval. Once the sample is confirmed, mass production cycles are usually 4-6 weeks, significantly aided by our automated production lines.
Our company will continue to strengthen research and development efforts for new products and technologies, integrate advanced management and technical resources, and strive to become your preferred one-stop precision manufacturing partner.
