Customer Projects for Coating Processes
Metzner provides a number of proven automation solutions for the automatic loading and unloading of coating carriers for CVD and PVD coatings. The abbreviations PVD (Physical Vapour Deposition) and CVD (Chemical Vapour Deposition) stand for different coating processes.
When loading the PVD spears, we differentiate between "single-loading" and "back-to-back loading". In addition to part loading, spacers are loaded onto the spears in addition to the parts. In single-loading, a spacer is located behind each individual insert, whereas in back-to-back-loading, two inserts are placed "back to back" and only then is a spacer loaded.
To implement "back-to-back-loading", a turning station is integrated into the machinery. This station is used to turn the corresponding insert by 180 degrees, loading it directly onto the respective spear.
