S-DLC |

Product Name:
|
S-DLC Coating |
|
Description:
|
Function:
The stamper is simply touched on the uniform and denser apexes of mirror surface
to create heat resistance
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: that of Seikoh Giken F-type), DVD-R mold, and Blue-ray Disc. The life-time is more than 3 million pieces.
