In the global maritime sector, hardware is constantly exposed to aggressive saline environments. Our investment casting process utilizes specialized 316L and Duplex Stainless Steels, engineered to provide maximum pitting resistance. We solve the industry's need for components that require zero-fail reliability in deep-sea operations.
Modern ship design focuses on fuel efficiency and carbon reduction. Through investment casting, we produce complex geometries that were previously impossible, reducing part weight by up to 30% while increasing structural integrity compared to traditional sand-cast alternatives.
As a global OEM manufacturer, JUNLONG Machinery provides a "One-Stop" solution. From mold design to CNC machining and surface treatment, we minimize lead times for international shipping fleets and maritime equipment providers in the US, Germany, and beyond.
Founded in 2014 and located in Weifang, Shandong, JUNLONG Machinery Co., Ltd. has established itself as a premier destination for precision investment casting. Spanning 60,000 square meters, our facility is optimized for the production of carbon steel, alloy steel, and stainless steel components with an annual capacity of 20,000 tons.
Our workforce of 200+ professionals, including 30+ dedicated engineering technicians, ensures that every marine part meets the rigorous standards of global industry leaders.
The marine casting market is undergoing a digital transformation. With manufacturing hubs shifting toward high-tech automation, JUNLONG stays ahead by integrating Automated Precision Casting lines. Our products serve as vital links in the supply chains of North America and Europe, complying with UL and TS16949 standards.
Our 2025-2030 roadmap focuses on "Smart Casting." This includes the implementation of AI-driven physical and chemical analysis to ensure zero-defect production. We are also expanding our deep-processing capabilities, moving from "Part Casting" to "Sub-System Assembly" for maritime propulsion and hydraulic controls.
We provide localized compliance support for diverse markets. Whether it's ASTM standards for the US or DIN standards for Germany, our technical documentation and quality assurance protocols are tailored to meet regional regulatory demands, ensuring smooth customs clearance and on-site integration.
Propeller components, deck hardware, valve bodies, and pump housings. Our parts are designed to withstand the cyclic loading and corrosive nature of seawater.
High-load bearing supports, brackets, and transmission parts. We utilize Q345 carbon steel and high-alloy steels for extreme mechanical durability.
Vibration-resistant investment castings for railway braking systems and connection supports, ensuring safety at high speeds.
From Mold Manufacturing to Precision Machining, we eliminate multi-factory communication risks. Our facility includes:
