The Heart of the Steelmaking Site,
Withstanding 1,000°C Heat and Heavy Loads

Scale adhesion and thermal fatigue are the inevitable fate of steelmaking rollers.
Seungjin Machinery minimizes line downtime risks and ensures process stability
with proven high-hardness coatings and heat-resistant alloy thermal spraying.

Micro-level Ultra-precision Pressing Technology,
Determining the Limits of Electrode Density

The key to battery energy density lies in the uniformity of electrode thickness.
Seungjin Machinery achieves 'zero-defect reproducibility' in the electrode process with micron-level ultra-precision roundness technology.

Robust Quality
Safeguarding Safety at Sea

We enhance the value of vessel lifespan with wear-resistant coatings
that have passed rigorous quality inspections.

High-Density Ceramic Coating,
Innovating Durability in Plasma Etching Environments

Unshaken even by Fluorine(F)/Chlorine(Cl)-based chemical gases, our Y₂O₃ (Yttria) coating
maximizes resistance to etching gases, dramatically increasing chamber utilization rates.

Surface Stability for Flawless Paper Production,
A Perfect Finish Without Streaks

In paper manufacturing rollers, even a microscopic wear variance in high-speed, wet environments can lead to quality defects.
Seungjin Machinery extends regrinding cycles and reduces production costs through uniform hardness and roughness control.

The Best Partners
Prove the Technological Prowess of Seungjin Machinery

From the history of Korea's steel industry to the future of the battery industry,
we are growing together with global leaders.
