SIMPAC operates a diversified business structure spanning press equipment, ferroalloy, rolls, trading, and auto parts. The largest revenue contributor is the ferroalloy segment, followed by press, casting, and industrial machinery sales.
The press segment has built its competitive position through build-to-order, high-mix low-volume manufacturing, and the company is known to have long held a leading position in Korea's press machinery market.
The ferroalloy segment produces ferromanganese, ferrosilicon, and silicomanganese, sourcing raw materials such as manganese ore and silica ore under annual contracts, with Hyundai Steel and POSCO as principal customers.
The roll segment supplies rolls for paper and steel manufacturing, while the trading segment handles intermediary import-export trade in aluminum, tin ingots, and steel.
The auto parts segment emerged as a new growth pillar after the acquisition of KDA, which brought drivetrain component revenue into the group, and the company is expanding production capacity for EV powertrain component output.
Competitively, the ferroalloy business shares the domestic market with DB Metal, Dongil Industry, Taekyung Industrial, and POSCO-affiliated producers, while the press business competes in a niche, high-mix, low-volume segment against a handful of domestic and overseas players.
In sum, SIMPAC runs a combined portfolio spanning materials (ferroalloy, roll), equipment (press), distribution (trading), and components (auto parts).
