In the modern era of precision agriculture, machinery is no longer just about brute force; it is about material intelligence and structural integrity. As a leading Agricultural Machinery Parts Manufacturer, JUNLONG Machinery Co., Ltd. (founded in 2014) leverages the sophisticated Lost Wax Casting (Investment Casting) process to deliver components that withstand the most abrasive soil conditions and high-stress environments.
Located in Weifang, Shandong—the heart of China's casting industry—our 60,000 square meter facility operates with a singular focus: bridging the gap between traditional metallurgy and AI-driven precision engineering. We don't just supply parts; we provide the backbone for tractors, harvesters, and seeding equipment that feed the world.
The global agricultural equipment market is shifting toward high-performance materials and complex geometries.
Integration of sensors into structural castings. We develop hollow-cavity parts that accommodate IoT sensors for real-time soil analysis and stress monitoring.
Transitioning from heavy cast iron to high-strength alloy steel. Reducing machinery weight improves fuel efficiency and reduces soil compaction, a key demand for EU and US markets.
Utilization of high-chrome alloys and specialized heat treatments to extend the life of tillage tools by 300% compared to traditional sand-cast components.
Global OEMs in Germany, USA, and Italy require "Zero-Failure" parts. Our ISO 9001 and TS 16949 certifications ensure that every batch of agricultural castings—from harvester blades to tractor brackets—is fully traceable.
Our engineering team collaborates with clients to optimize part geometry, reducing material waste by up to 15% and lowering the total cost of ownership (TCO) for global agricultural distributors.
Combining 3D printing of wax patterns with traditional investment casting allows us to deliver prototypes in weeks rather than months, accelerating the time-to-market for new equipment models.
At JUNLONG, we are investing in the next generation of casting technologies to stay ahead of the "Industry 4.0" curve. Our roadmap includes:
Operating globally requires adhering to strict environmental and safety standards. We offer:
✅ REACH & RoHS Compliance for European markets.
✅ UL Certification for electrical-adjacent agricultural components.
✅ Localized logistical support for DDP (Delivered Duty Paid) shipping to North America and the EU.
✅ On-site engineering audits for strategic long-term partners.
Investment casting provides a superior surface finish (RA 3.2-6.3) and much tighter tolerances. This reduces the need for expensive secondary machining and allows for complex internal geometries that sand casting simply cannot achieve.
We typically recommend 4140 or 8620 Alloy Steel, or High-Chrome Iron. Through our specialized heat treatment processes, we can achieve surface hardness levels up to 60 HRC while maintaining core toughness.
For new toolings, the mold development takes 3-4 weeks. Samples are provided within 7 days thereafter. Mass production usually ranges from 30 to 45 days depending on the complexity and volume.
We utilize Spectrometers for every melt and provide 3.1 material certificates. Every part undergoes magnetic particle inspection (MPI) or ultrasonic testing (UT) if specified, ensuring internal integrity.
