Function:
The stamper touch on the uniform and denser apexes of mirror surface to create heat resistance.

Combining the characteristics of graphite lubrication and diamond hardness:

DLC diamond-like carbon, diamond-like carbon, diamond-like film, steel-like carbon, diamond film color: bright black

DLC diamond-like carbon, diamond-like carbon, diamond-like film, steel-like stone carbon, hardness of diamond film: HV1750~HV3500

DLC diamond-like carbon, diamond-like, diamond-like film, steel-like stone carbon, film thickness of diamond film: 0.5-3.5um

DLC diamond-like carbon, diamond-like carbon, diamond-like film, steel-like carbon, diamond film heat resistance temperature: 400 ℃

DLC diamond-like carbon, diamond-like carbon, diamond-like film, steel-like stone carbon, friction coefficient of diamond film: 0.08~0.12

Effects:
1. Lower friction, prolong life of mold, mirror plate, and stamper.
2. Keep stamper at constant temperature when forming the disc. As the molten polycarbonate flows out from the center, the temperature curve decreases more smoothly; thus, allowing the grooves and pits to be formed more easily, which can improve the yield rate and shorten the cycle time. (In this case, the time required for formation).

Application:
Applied in molds (Ex: Seikoh Giken F-type), DVD-R mold, and Blue-ray Disc.
