Daedong Metal traces its roots to a foundry division established in 1947 and is an affiliate of Daedong Group, Korea's largest agricultural machinery maker.
The company operates with an annual casting capacity of 70,000 tons, producing agricultural machinery castings, automotive engine cylinder heads, MCV and hydraulic parts for construction equipment, and vacuum pump parts for semiconductor manufacturing.
Its clients include Hyundai Motor Group, to which it directly supplies cylinder heads, and Volvo, which receives MCV and hydraulic components; it also supplies core cast vacuum pump parts to global equipment makers including Edwards of the UK, the world's leading semiconductor vacuum pump manufacturer.
The finished vacuum pumps from these suppliers are deployed in production lines at Samsung Electronics, SK hynix, TSMC, and Micron.
In shipbuilding, the company has expanded its customer base beyond HD Hyundai Heavy Industries to include Hanwha Engine and STX Engine, and it also trades with Japanese industrial machinery firms Kawasaki and KYB as well as semiconductor equipment makers.
As of last year, revenue from customers outside the parent group reached 87.8%, up 2.1 percentage points from 2023, reflecting a broadening external customer base.
The company is regarded as a technology leader among domestic foundries in producing high-difficulty automotive cylinder heads and blocks, and it is now extending its portfolio into new businesses such as robot actuator materials and smart-farming structural materials, aligned with the group's shift toward robotics and mobility.
