Hongliang Boat Technology: Pioneering the Future

Nantong Hongliang Boat Technology Co., Ltd. is a manufacturer and processor of nonferrous metals—producing copper and aluminum castings—located in the Yangtze River Delta, one of China’s six major metropolitan regions. The company is bordered by the Yellow Sea to the east, the Sutong Bridge to the south, Nantong Port to the west, and the Xinchang Railway to the north. It lies just a few kilometers from Nantong Airport and faces Shanghai and Suzhou across the river, enjoying an excellent location with convenient and efficient transportation links.

Our company’s factory covers a total area of 5,000 square meters, with a casting workshop spanning 3,000 square meters and a machining workshop covering 2,000 square meters. We produce centrifugally cast friction‑plate components in copper, with diameters up to 2.5 meters, and employ a cutting-edge centrifugal casting process for high‑lead bronze castings. Our copper bushings can be cast in weights of up to 2 tons. Equipped with a full range of advanced production machinery and robust manufacturing capabilities, we achieve an annual output value of approximately RMB 40 million. Our facilities include medium-frequency induction furnaces, horizontal split‑mold core‑shooting machines, CNC lathes, Heraeus pre‑furnace analyzers, and Italian GNR spectrometers, along with a comprehensive suite of testing equipment.

This year, the company has commissioned a new set of negative-pressure investment casting production lines. Compared with traditional methods, this casting technology offers distinct advantages and has been hailed as a “green revolution in the casting industry.” The company boasts a team of highly qualified technical professionals and an experienced workforce, and it is equipped with ProCast, a casting process simulation software developed by UES in the United States. With these capabilities, we can tailor products to meet customer specifications and provide timely support whenever you need it.

The company places great emphasis on its quality assurance system, having successfully obtained ISO 9001:2000 certification and holding the official certificate. Committed to delivering superior quality, the company boldly pursues innovation, adheres to a product philosophy of high standards, high aspirations, and premium excellence, and strives to create value for our customers, employees, and society. Upholding a people‑centric approach, conducting business with integrity, working tirelessly, and continuously innovating—crafting exceptional products through unwavering character—is the company’s steadfast development goal.

The company adheres to a business philosophy of surviving through quality, growing together with our customers, and winning the market through integrity. We consistently place customer interests at the forefront and orient ourselves toward customer satisfaction, wholeheartedly delivering high‑quality castings. With a scientific and sincere approach, we strive to earn broad recognition from our clients, earning their praise and trust.

In July 2001, the company successfully piloted a new process for large‑scale centrifugal casting of high‑lead bronze and double‑flanged copper bushings, producing castings weighing up to 2 tons. High‑lead bronze exhibits self‑lubricating properties and reduces the coefficient of friction, making it ideal for wear‑reducing bearings in aerospace engines and various cone and gyratory crushers operating under heavy loads and high impact conditions. The high‑lead bronze components manufactured by our plant have been put through trials at numerous domestic industrial and mining enterprises and have received widespread approval. Furthermore, we have produced replacement parts made of high‑lead bronze for U.S.-imported equipment used in the Three Gorges Project—such as Simons crushers and 23‑cubic‑meter electric shovels—and these components, once installed and commissioned, have all met or exceeded the expected service life of high‑lead bronze parts.
