Stock Preparation and Variability

The paper production is a combination of very complex sub processes and stock preparation is one of the main areas where most of the variability of the final end product is created. Fibers from recycled paper, wood, and cellulose must be treated mechanically and chemically before they are sent to the stock preparation area and in the stock preparation those different fiber and additive streams are combined to one big stream going to the Paper Machine.

The key for the Stock Preparation area is consistent and accurate consistency control with the proper Agitation. Conmark has developed over the several years a "Total Consistency Management" (TCM) concept for the stock preparation area that provides the capability of reducing drastically the variability created by the Stock Prep area in the past.Stock Prep Area

Consistency is the foundation of the papermaking process. Consistency measurement and control has a significant impact on both product variability and manufacturing costs. Even slight improvements in the control of consistency throughout the mill can result in major savings because stabilizing the wet end and reducing machine directional basis weight variability.

Although consistency is almost universally recognized as the most important variable in the manufacture of pulp & paper, it is often the most neglected. Good consistency control requires that the entire system be engineered and designed correctly.

The improved understanding of the variability in the paper making process helps mills to improve their bottom-line directly with the very small investments in the Stock Preparation area. Stock Preparation area is excellent place to implement Six Sigma Principles for continuous process improvements.  Ultimately, reward is measured by increased profitability and increased customer satisfaction.

Ultimately, reward in the improvements in stock prep are measured by increased profitability and increased customer satisfaction. To effectively improve the performance of your process, you must be able to measure quantitatively what your customers consider critical about your products or services.
