PVD technology can provide tools with high hardness, wear resistance, heat resistance and sufficient toughness and strength. The tool coated with PVD coating not only greatly increases the service life, but also meets the requirements of modern machining of high efficiency, high precision and high reliability.

PVD coating can provide molds with high hardness, high wear resistance, low friction coefficient, high chemical stability and other characteristics, and is widely used in stamping molds, die-casting molds, injection molds and other industries.

The diamond-like carbon film is mainly composed of a three-dimensional network of sp3 hybrid carbon atoms with a diamond structure and sp2 hybrid carbon atoms with a graphite structure. It is used in automotive parts, aerospace, machinery, electronics, optics, decorative appearance protection, biomedicine, etc. The field is widely used.

Under the action of the strong electric field in the plasma zone, the positive ions of nitrogen and hydrogen bombard the surface of the workpiece at high speed.  The high kinetic energy of the ions is converted into heat energy, which heats the surface of the workpiece to the desired temperature.  Due to the bombardment of ions, atomic sputtering occurs on the surface of the workpiece, which is purified...
