In the modern industrial era, the demand for Custom Precision Cast Mechanical Components has shifted from mere part replication to high-level engineering integration. As a leading manufacturer, JUNLONG Machinery understands that precision casting (Investment Casting) is the backbone of critical industries including aerospace, automotive, and heavy-duty logistics.
Global supply chains are currently facing a transformative period. The rise of Industry 4.0 requires components that offer not just dimensional accuracy but also material integrity that can withstand extreme thermal and mechanical stresses. Our manufacturing processes utilize the Lost Wax Casting technique to produce complex geometries that would be impossible or prohibitively expensive to achieve through traditional machining.
The global precision casting market is projected to reach $20.5 billion by 2028. We are positioned at the forefront, providing "Information Gain" through our R&D and proprietary alloy formulations.
Founded in Weifang, Shandong, JUNLONG Machinery Co., Ltd. has grown from a local foundry to a global powerhouse in precision manufacturing.
A massive production footprint dedicated to carbon steel, alloy steel, and stainless steel investment casting with an annual capacity of 20,000 tons.
Staffed by over 200 employees, including 30+ senior engineering technicians specialized in metallurgical analysis and CNC deep processing.
We go beyond standard casting. Our facility provides tailored metallurgical solutions to meet specific mechanical property requirements.
Utilizing high-grade carbon steel for industrial components requiring high structural integrity. Ideal for auto transmissions and heavy machinery frames.
Superior corrosion resistance using SS304, SS316, and duplex grades. Widely applied in chemical processing and marine environments.
Specialized low-alloy high-strength steels. Our 16Mn casting provides exceptional toughness for railway and construction components.
Engineered for extreme wear resistance. Perfect for mining equipment, grinding media, and abrasive material handling.
