Coating Bars
3
D-Bar / E-Roll
A one-piece coating bar with no wound wire. The grooves are formed directly by thread rolling, so there is no wire breakage, spreading, or debris trapping. Produced in outer diameters of φ6–30 mm and lengths up to 7,500 mm, with film thickness adjustable from 3 ㎛ to 450 ㎛.

DLC Coating Bar
A coating bar that achieves diamond-grade hardness through carbon-based plasma coating. With a hardness of 1,500–2,000 HV and a friction coefficient of 0.15, it improves both service life and coating quality. Supplied in two versions: for research and development, and for production equipment.

Mirror Roll / Matte Texture Roll
Micro-textured transport rolls control air entrainment and grip between the film and roll to reduce blocking, slippage and surface damage. Optional DLC coating improves wear resistance, service life and antistatic performance. GHT helps select the roll surface for stable web handling and production yield.
