  • Segezha’s Vyatka Plywood Plant implements lean principles in Russia

    Segezha Group, a subsidiary of Sistema PJSFC and a leading Russian vertically integrated forest holding with a full cycle of logging and advanced wood processing, informed that Vyatka Plywood Plant (Kirov Region of Russia) is successfully implementing methods of lean production and efficiency improvement.

    According to the announcement, the company established working groups to identify production-related problems and ways to tackle them. Economically sound improvement suggestions of employees are taken into account while implementing production processes, and innovators receive financial rewards.

    Thus, starting this spring a working group for efficiency improvement acts in the longitudinal ply shop. The group includes Svetlana Kochkina (In-shop Process Technician), Tatyana Marikhina (Forewoman), Alexey Gribanov (Sawyer) and Nikolai Musinov (Mechanical Technician). The main task of the group is to counteract a critical defect on high grade veneer, which is known as “pinhole”. By “pinholes”, experts mean pinpoint damages of a surface layer of finished products.

    The root cause of the defect was analyzed amid materials, equipment and production technologies. It turned out that the products were damaged by the harvesting equipment and rollers of bark peeling machines as well as by conveyors while being crosscut and peeled. The improvement suggestion implied the adjustment of the program, which controls operations of a log storage conveyor, closure of chain conveyor dents and extension of crosscutting of the front edge.

    In January, before the working group was set up, the “pinhole” defect reached its peak value of 14.66%. In April-May, the percentage of such defective products dropped down to 0.95%. As a result, the output of high-grade plywood at the mill increased by 9% on average, and the amount of veneer used for patching purposes upon grading and separation of A-grade products dropped by 9%. The so called “percentage of grade compliance” on the patching line increased by 10%.

    “The role of working groups is particularly important when methods of lean production are being implemented. This is an efficient way to encourage personnel for active involvement into production management. Now, every staff member can suggest process improvements and take part in the company development. The task of the management is to support the culture of continuous improvement and assist with the implementation of specific initiatives.”Alexey Stepanov, Management Board member, Vice-President of Segezha Group, Executive Director of Vyatka Plywood Mill

    Earlier, Vyatka Plywood Plant started production of special kinds of plywood as part of its modernization program in Russia.
