Who We Are
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, we represent a high-quality casting supplier integrating precision casting and deep processing. Our WCB (Water Quenched Carbon Steel) castings are engineered specifically for the mining industry's most demanding applications.
ASTM A216 WCB is the gold standard for mining components. Its balance of tensile strength and ductility ensures that parts like crusher liners and excavator teeth can withstand massive impact without catastrophic brittle failure.
As global demand for lithium, copper, and iron ore surges, mining operators are shifting toward "Zero-Downtime" strategies. Custom WCB castings reduce the Mean Time Between Failures (MTBF), providing a clear competitive ROI.
Our localized support spans Germany, USA, and Italy. We ensure full compliance with ISO 9001 and TS 16949, meeting the stringent safety requirements of international mining jurisdictions.
The industry is moving beyond traditional "pour-and-cool" methods. JUNLONG is integrating AI-driven solidification simulation and 3D sand printing for complex internal geometries. This ensures that every WCB casting is free from internal porosity—a critical factor for parts operating under 500+ tons of pressure.
Our future roadmap includes the adoption of smart alloys that incorporate micro-alloying elements to enhance wear resistance by 30% compared to standard WCB specifications, reducing the carbon footprint by extending the lifecycle of heavy equipment.
WCB castings for bucket linkages and pivot pins in ultra-class excavators. Engineered to operate in temperatures ranging from -40°C in Nordic mines to +50°C in Australian outbacks.
Precision-cast pump housings and valve bodies for mine dewatering and slurry transport. High dimensional accuracy ensures leak-proof performance in high-pressure subterranean environments.
Custom structural components for vibrating screens and flotation cells. Our lost-wax process achieves the surface smoothness required to prevent material buildup and corrosion.
Customer Value: Eliminates communication costs, quality risks, and delays associated with multi-factory collaboration, enabling full-process quality traceability with a single point of responsibility.
We have obtained ISO 9001, TS 16949, UL, and other quality management system certifications, ensuring process control over every production detail and continuously pursuing and improving product quality to achieve high customer satisfaction.
