Industry-standard OEM/ODM components for global machinery leaders
As the global population surges toward 9 billion by 2050, the demand for efficient, high-yield agricultural practices has never been more critical. This pressure has catalyzed a technological revolution in the agricultural machinery sector. Investment casting (also known as lost-wax casting) has emerged as the gold standard for manufacturing complex, high-durability components that can withstand the rigorous demands of modern farming.
Historically, sand casting dominated the industry. However, as machinery becomes more sophisticated—incorporating GPS, automation, and high-torque engines—the need for tighter tolerances and superior surface finishes has driven a shift toward investment casting. Today, the global market for agricultural investment castings is expanding at a CAGR of 5.8%, with China at the forefront as the world's primary supply hub.
Europe and North America remain the largest consumers of high-end precision components, focusing on large-scale harvesters and autonomous tractors.
Shift from standard grey iron to high-manganese steel and specialized alloy steels like Q345 for enhanced impact resistance.
Integration of AI-driven simulation software to predict shrinkage and porosity before the first wax pattern is even injected.
Founded in 2014 and located in Weifang, Shandong, the heart of China’s industrial manufacturing corridor, JUNLONG Machinery Co., Ltd. has established itself as a premier destination for high-precision investment castings. Covering 60,000 square meters, our facility is engineered for scale and precision.

The transition from traditional "foundry work" to "precision metallurgy" is defined by several key technological milestones that JUNLONG Machinery is currently pioneering:
Utilizing 3D printing for wax patterns. This eliminates the need for expensive aluminum molds during the R&D phase, reducing lead times from weeks to days for custom agricultural components.
For high-performance alloy steels used in aerospace and high-tech agricultural sensors, vacuum casting ensures zero gas porosity and maximum structural integrity.
Every casting mold is digitally simulated using Magmasoft or ProCAST. This allows our engineers to visualize the solidification process, ensuring that critical stress points are reinforced.
We don't just provide parts; we provide structural solutions. For global OEMs, we offer "Integrated Manufacturing Capabilities":
Harvester blades, tractor hitches, seed drill components, and plow shears. Our Q345 castings offer the perfect balance of ductility and hardness for soil-engaging tools.
Excavator bucket teeth and heavy-duty hinges. We utilize high-chrome alloy steels to ensure these parts survive extreme abrasion.
Precision valve bodies and ship spare parts. Our stainless steel investment casting prevents corrosion in saltwater and high-pressure oil environments.
Investment casting provides superior dimensional accuracy (CT4-CT6) and surface finish (Ra 3.2-6.3), significantly reducing or eliminating the need for secondary machining. This is vital for complex components like harvester internal gears or hydraulic valve mounts.
Carbon steel (like Q345 or 1045) is common for structural parts. For high-wear areas, we recommend high-manganese steel or alloy steels containing Chromium and Molybdenum for enhanced toughness and fatigue resistance.
We are TS 16949 certified, which is the rigorous standard for the automotive industry. This management system is applied to our agricultural line, involving APQP, PPAP, and FMEA processes to ensure zero-defect delivery to our clients in the USA, Germany, and Italy.
Mold manufacturing typically takes 2-3 weeks. First article samples are provided within 1 week of mold completion. Mass production usually ranges from 4-6 weeks depending on the complexity and volume.
