JUNLONG Machinery Co., Ltd., established in 2014 in Weifang, Shandong, represents the pinnacle of China's industrial precision. Spanning 60,000 square meters, our facility produces 20,000 tons of high-grade mechanical parts annually. We specialize in the metallurgical fusion of carbon steel, alloy steel, and stainless steel, serving as a Tier-1 global supplier.
Our engineering team consists of over 30 technical masters who bridge the gap between complex CAD designs and physical reality through advanced investment casting (lost wax) methods. We are not just a foundry; we are an integrated center for engineering excellence and deep processing.
Leading the shift towards Industry 4.0 in Investment Casting
The global investment casting industry is undergoing a seismic shift. Modern mechanical parts require higher strength-to-weight ratios and tighter tolerances than ever before. Our technical roadmap focuses on the integration of Digital Twin Simulation and Automated Shell Room Environments.
| Phase | Technological Focus | Outcome for Clients |
|---|---|---|
| Short Term | Vacuum Induction Melting (VIM) for super-alloys | Elimination of gas porosity; enhanced fatigue life. |
| Medium Term | AI-Driven Quality Inspection (Computer Vision) | Zero-defect delivery for automotive & rail sectors. |
| Long Term | Hybrid 3D Printing & Lost Wax Integration | Rapid prototyping of complex internal geometries without tooling costs. |
Our facilities feature internationally advanced automated production lines. Physical and chemical analysis labs ensure that every batch of mechanical parts meets the exact metallurgical profile required for extreme industrial use.
Exporting to the USA, Germany, Italy, and Canada, we understand international standards (ASTM, DIN, JIS). We bridge the gap between East and West through reliable logistics and transparent communication.
Holding ISO 9001, TS 16949, and UL certifications, we offer full-process quality traceability. From mold manufacturing to surface treatment, every step is audited to mitigate risk.
We don't just "cast and ship." Our secondary machining workshop includes horizontal/vertical CNC centers, grinding, and specialized milling to deliver ready-to-assemble components.
Engineering specific solutions for critical global infrastructure
Cast components for harvesters and tractors in the Midwest US or Europe require high wear resistance. Our alloy steel castings provide the toughness needed for high-impact soil contact.
For coastal industrial hubs, we provide stainless steel investment castings that resist salt-spray corrosion for ship spare parts and pump valves.
Safety is paramount. Our precision steel casts for railway parts undergo non-destructive testing (NDT) to ensure structural integrity under high-speed load cycles.
In the Middle East or SE Asia's urban booms, excavators and loaders rely on our heavy-duty casting components to withstand extreme heat and dust.
Navigating international trade requires more than just good parts. It requires Regulatory Compliance. At Junlong, we provide:
