OHSEONGTECH designs and manufactures in-house the core equipment and auxiliary machinery that make up a complete coating line.

Coating Machine Line
COATING LINE

From unwinder to rewinder —
we build the entire coating line in-house

From Coaters tailored to viscosity, coating weight and substrate, to precision drying chambers, lamination & winding equipment, and auxiliary machinery for measuring, mixing and slitting — we configure it all into a single line. Every machine is engineered for safety, precision and energy savings.
