Changhan Metal Co., Ltd. is a specialized non-ferrous metal manufacturer located in the Noksan National Industrial Complex in Gangseo-gu, Busan. We manufacture precision parts for machinery and turbines through a consistent production process, ranging from the melting and casting of non-ferrous metals such as copper alloys to rough and finish machining. Based on our accumulated technical expertise, we supply high-quality finished non-ferrous metal castings to industries across the board.

"Our company is a manufacturer of non-ferrous metal castings and finished products through rough and finish machining, producing and supplying various non-ferrous metal products to the market while prioritizing quality as our most important value."

Business Areas

• Non-ferrous Metal Casting: We precisely melt and cast non-ferrous metal alloys, including copper castings, using CO2 sand casting and centrifugal casting methods. We stably produce casting materials of various specifications and materials required for industrial machinery and plants.
• Precision Machining and Finished Product Manufacturing: We manufacture finished products according to specifications by performing rough and finish machining on cast non-ferrous metal parts. We specialize in machining turbine parts and rotating equipment parts that require strict dimensional precision and durability.

Products

• Copper Alloy Bushings and Liners: These are wear-resistant copper alloy castings used in the rotating and friction parts of industrial machinery and heavy equipment. They are characterized by a dense structure and excellent durability achieved through centrifugal casting and finish machining processes.
• Turbine Parts (Ring / Gland): These are precision-machined non-ferrous metal parts in the form of rings and glands, installed in power generation facilities and industrial turbines. They are manufactured through precision casting and precision cutting to withstand high-temperature and high-pressure environments.

Special Notes

• Integrated production system from casting to precision machining: We possess a production line capable of handling everything in-house, from raw material melting and casting processes to final finish machining. This allows us to achieve shorter lead times and thorough quality control.
• Professional technical expertise in copper alloy casting: We operate various casting methods such as sand casting and centrifugal casting, and possess specialized know-how in processing copper alloy parts that require high wear resistance and mechanical properties.

Recruitment Information

• Main Hiring Positions: Caster (sand casting, centrifugal casting, melting, molding, sand removal), Quality Control Inspector (product inspection, measurement and delivery management), Accounting Clerk
• Benefits: Four major social insurance programs (National Pension, Health Insurance, Employment Insurance, Industrial Accident Compensation Insurance), severance pay, lunch provided

💡 A Word from JOBPLOY
The casting and machining site of Changhan Metal Co., Ltd. primarily involves working with high-temperature melting furnaces and heavy-duty casting machinery, so wearing safety gear and following safety protocols is essential. As it is a small-scale, high-intensity workplace, close collaboration with managers and colleagues is important, and learning basic Korean work instructions and safety terminology will be of great help for a smooth transition. JOBPLOY recommends this for those who value technical skill development.
