Voith Quality Control System (QCS) OnQuality

    Voith’s Quality Control System (QCS) OnQuality is a smart and integrated concept to enable producers to gain control over production processes and product quality. It offers the opportunity to stabilize and optimize the product quality and the production process while increasing productivity and decreasing operation and maintenance costs.

    Our QCS is the latest in quality control systems for online analysis of paper properties.

    It is a system for paper makers with a passion for high paper quality who want to meet their customer’s expectations and increase their operation efficiency. Our system is smart and modular, and compact to fit in almost any paper machine. Its attractive lifecycle costs improve the competitiveness of the production through improved reliability and decreased maintenance need. Production value is increased as quality requirements can be met reliably and consistently. Detailed insight into production and steps to improve processes and maintenance activities are provided to give the paper maker a high amount of control over machine and production. In-use times of plants are increased, and target KPIs can be met fast and consistent.

    Products & Solutions

      The measurement frames are built to be integrated into all paper machines even with small available space and in high temperature Environments.

      Measurement plates and heads are highly standardized components that ensure a plug and play configuration of sensors. Sensors have a small format that is easy to handle. The QCS is based on the modular automation platform ComCore. ComCore allows an easy integration of the QCS into a customer automation system and provides clear information and access to the paper maker.


      OnQuality.Sensors are compact, robust and include state of the art technology. They include a smart sensor and comprehensive diagnostic functions and insure easy access for maintenance and system extension. Interfaces are easy to use. All sensors include the new processor board with powerful signal processing capacity and standardized communications.

      The Voith quality control system is based on the modular automation platform ComCore. The modularity allows easy integration of your quality control system into existing automation systems and provides clear information flows. The easy-to-use user interfaces allow direct access and optimization of the quality parameter profiles.

      Success Story

        Decor paper specialist Ahlstrom-Munksjö modernizes its quality control system with ComCore

        Due to the technical performance spectrum, the Unterkochen team decided to modernize the quality control technology with the ComCore QCS system by Voith Digital Solutions. ComCore is an automation platform developed specifically for the paper industry. It comprises digital assistance, measurement and control systems that can also be expanded with the OnEfficiency and OnCare product families.
        The start-up processes have accelerated considerably, and the changeover times have been shortened.
        Guido Feuchter is responsible for the rapid adaptation of the parameters on the ComCore platform to the desired product in the event of a grade change.
