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, the company is a high-quality casting supplier integrating precision casting and deep processing. We bridge the gap between complex engineering requirements and large-scale manufacturing efficiency.
China's shipbuilding and marine component industry has evolved from a low-cost hub to a global leader in high-precision technology. Manufacturers like JUNLONG leverage an integrated supply chain—from raw material sourcing to advanced CNC machining—drastically reducing lead times while maintaining strict adherence to international maritime standards.
Modern precision foundries are adopting digital twin technology and automated wax injection systems. These "Smart Foundries" minimize human error in complex geometries required for ship propellers, engine valves, and hull components, ensuring consistency across thousands of production units.
Environmental regulations (IMO 2020/2030) are driving the demand for lightweight, high-strength alloys. Precision casting allows for "near-net-shape" production, which minimizes material waste and energy consumption during secondary machining, aligning with global ESG goals.
Ship parts are subjected to some of the harshest environments on Earth—constant saltwater exposure, extreme pressure, and high-frequency vibration. Our precision foundry solutions address these challenges through specialized metallurgical control and advanced lost-wax techniques.
Equipped with internationally advanced automated casting production facilities and comprehensive physical and chemical analysis equipment, the company significantly enhances manufacturing efficiency and product quality stability.
Leveraging strong engineering capabilities, a complete quality control system, and advanced management systems, we export to Germany, the United States, Italy, and Canada, serving high-end clients in Europe and America.
Beyond marine parts, we serve automotive, rail transportation, engineering machinery, material handling, agricultural machinery, and petroleum sectors with certified precision components.
The choice of material is paramount. We offer a spectrum of alloys tailored for specific shipboard functions:
In the maritime industry, a single component failure can lead to catastrophic results. Our commitment to reliability is backed by rigorous certifications and a multi-stage inspection process.
Certifications: JUNLONG has obtained ISO 9001, TS 16949, and UL quality management system certifications. This ensures process control over every production detail, from the initial melt to the final surface treatment.
Inspection Protocols: Our facilities include SPECTROMETERS for material analysis, X-RAY flaw detection, Ultrasonic testing, and CMM for dimensional accuracy.
We utilize a full industrial chain integrated manufacturing capability. From mold manufacturing to machining (CNC lathes, milling, grinding) and surface treatment, we ensure a seamless transition from concept to finished product.
As a world-class precision casting supplier, we provide high-quality products, services, and solutions to global industry leaders. Whether you are in Europe, America, or Asia, our engineering team is ready to support your next project.
