  • PVD Coating(color)Process Control
    Sep 06, 2018

    The process parameters for each collating (color) are stored in recipes with different process steps. During the process, all relevant process parameters are continuously monitored and controlled by an automatic control system. By storing the relevant parameters in recipes and controlling and monitoring them during the processes, it is possible to have an excellent reproducibility of the coating quality. PVD yields up to 98% have been achieved on a long-term basis.

    The combination of these, specially designed installations with high flexibility and reliability and automatically controlled processes enable excellent reproducibility of a magnitude of colors on different substrate materials in multiple machines worldwide at any moment in time. Faucets assembled of brass, zinc and ABS products will show no color deviation, even if the substrate materials are purchased, electroplated and PVD coated in different locations.

    1 A PVD chamber is usually operated in the E-3 or E-2 mbar range (1Torr+1.333 mbar) and has a base pressure in the E-7 mbar range. Pressures such as this can be obtained using oil diffusion or turbomolecular pumps. To obtain a vacuum on the high-pressure side of the turbo pumps and to pump down the system from atmospheric pressure a rotary vane and root pumps (forevacuum) are used.
