Top-quality service manufacturer in the ship engine field, specializing in the machining and production of piston crowns, piston heads, cylinder covers and piston skirts for two-stroke engines.

Haewon Machinery & Engineering: Manufacture and supply of superior-grade machined parts to ship engine and construction equipment manufacturers


As recently as the late 1980s, piston crowns for large ship engines could not be fabricated domestically due to a lack of proper materials and welding techniques. Recognizing this need to develop the industry, we formed an academic-industry-research consortium with the Korea Institute of Machinery & Materials and Chungnam University Research Institute of Industrial Technology. The technologies that were developed as a result of these efforts received quality certification from the Lloyd’s Register (LR) and Hyundai Heavy Industries in 1990. Building on this success, we established Haewon Machinery & Engineering, a factory specializing in piston crown production, in Gimhae in June 1992. Today, we supply superior process equipment, shipbuilding products, and weld repair products to ship engine makers and shipping companies. Using our advanced technological expertise and adhering to only the strictest quality standards, we have also made inroads into the field of special equipment for on-land construction, and are making our mark in manufacturing and rebuilding services for high-grade drilling components.
