Jinhecheng Machinery manufactures high‑precision mirror‑finish hard chrome‑plated rollers for printing, film coating, laminating, leather and paper calendering applications.
Using high‑quality carbon steel substrate with uniform hard chrome plating, our rollers reach hardness HRC58‑62. Strong coating adhesion avoids peeling, pinholes and cracks. After fine grinding and mirror polishing, surface roughness can be as low as 0.02 μm.
The mirror‑smooth surface enables even coating, accurate ink transfer and high finished‑product yield. Good wear‑resistance and anti‑corrosion performance resist oil, moisture and weak acid‑alkali media for long‑term stable high‑speed running.
Besides new roller customization, we provide refurbishment services: old‑roller stripping, re‑plating, straightening and precision repair. Each product is tested for coaxiality, hardness and flatness before delivery.
We support large‑size and special‑condition custom orders with adjustable chrome thickness and installation structures. As original factory, we ensure stable output and short lead time for precision industrial transmission.
