High-strength components designed for the rigorous demands of US naval and commercial shipping sectors.
Safety-critical braking components for Class 8 trucks operating across American highways.
Intricate metal components with superior surface finish for high-tech American industrial applications.
Reinforced support components for earthmoving and lifting equipment in the US market.
The manufacturing landscape in the United States is currently undergoing a profound transformation. As the world moves toward "Industry 4.0," US businesses are increasingly prioritizing supply chain resilience and technological integration. There is a growing demand for precision-engineered components that can withstand extreme environments, particularly in the automotive, aerospace, and energy sectors.
Despite the push for domestic "reshoring," the reality of modern commerce necessitates a hybrid sourcing strategy. American manufacturers require partners who offer not just low costs, but significant Information Gain—meaning expertise that optimizes design for manufacturability, reduces material waste, and ensures ISO-certified reliability.
Advanced lost wax and investment casting techniques ensuring tolerances within 0.05mm for complex American machinery.
Full compliance with TS 16949 and UL standards, providing peace of mind for safety-critical US infrastructure.
Optimized logistics from our Shandong hub to major US ports, reducing lead times for critical components by 30%.
Founded in 2014 and headquartered in Weifang, Shandong, JUNLONG Machinery Co., Ltd. has evolved into a premier high-quality casting supplier. Spanning 60,000 square meters, we maintain an annual capacity of 20,000 tons of precision castings and machined parts.
Our facility is equipped with internationally advanced automated production lines and comprehensive physical and chemical analysis equipment. We specialize in materials critical to the US market, including carbon steel, alloy steel, and stainless steel.
Unlike traditional foundries, Junlong offers a Full Industrial Chain. From initial mold manufacturing and precision casting to advanced CNC machining and surface treatment, every step is controlled in-house. This eliminates communication gaps and reduces quality risks for our American clients.
Our laboratory utilizes Spectral Analysis, Magnetic Particle Inspection, and CMM (Coordinate Measuring Machines) to ensure that every part—whether it's for a US railway or a petroleum valve—meets the exact mechanical properties required.
By integrating energy-efficient induction furnaces and waste-sand reclamation systems, we align with the ESG (Environmental, Social, and Governance) goals of modern US corporations. Our efficiency directly translates to cost savings without compromising on the durability of the final product.
Providing high-strength carbon steel casting for truck parts and auto transmissions. Essential for the massive US logistics network and light-vehicle manufacturing hubs in the Midwest.
Lost wax castings for excavators and cranes. Supporting the US Infrastructure Investment and Jobs Act by providing durable wear parts for construction machinery.
Alloy steel cable protectors and pump valve accessories for the unconventional oil and gas fields in Texas and North Dakota. Designed to resist corrosion and high pressure.
Junlong has obtained ISO 9001, TS 16949, and UL certifications, ensuring process control over every production detail.
For custom precision castings, the mold development takes 2-3 weeks, with production following in 4-6 weeks. Sea freight to the West Coast takes approximately 18-22 days, and to the East Coast, 30-35 days. We also offer expedited air freight for urgent prototypes.
Every batch of material is tested for chemical composition and mechanical properties (tensile strength, yield strength, elongation). We provide 3.1 Material Certificates and can accommodate third-party inspections (SGS, BV) required by many US industrial firms.
Yes. While we have a high annual capacity, our flexible production lines allow us to handle medium-to-small batches for specialized engineering projects in sectors like shipbuilding and agricultural machinery.
We provide comparable precision and material quality (often using the same ASTM standards) at a more competitive cost structure due to our integrated supply chain and optimized energy costs in Shandong's industrial hub.
