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.
