PVD Coating

 

By processing at temperatures around 500°C, a coating with excellent wear and galling resistance can be formed for high-precision molds.

Product Examples

 

 ► Characteristics of each coating

●Film type characteristics

●Application

TiNAbrasion resistance, release properties, seizure resistance
TiCNHigh wear resistance, low friction coefficient
CrNCorrosion resistance, heat resistance, mold releasability
TiAINHigh hardness, heat resistance (high temperature oxidation resistance)

Base coating thickness: 2 to 4 μm

●TIN coating layer cross-sectional structure

 ►Hi-Tensile Cerac (Improved TiN)

 

As the strength of high-tensile steel sheets has increased in recent years, the load on dies and the demand for precision have grown, and the need for longer life through PVD treatment has increased. In order to improve life, we aim to increase the life of dies by minimizing coating defects.
In addition, by combining this with base nitriding (radical nitriding), we can expect to further extend life.

High-Ten Cerac

 

Coating defects (pinholes) can cause adhesion of the workpiece and peeling of the coating.

1. Adhesion of workpiece

2. Increase in adhesion

3. Minor galling (coating peeling)

 ►Effective processing range

・PVD treatment:  φ720×800 - MAX500㎏

・Nitriding:  φ600×600 - MAX300㎏

Depending on the shape and size of the mold, it may not be possible to treat only the required parts.
Please check with our sales staff in advance about the applicable items.
(Generally, it is not possible to treat the entire surface.)
