Purpose: The article includes characteristic of the extrusion moulding as the most popular method of the plastics processing industry. Statistical analysis and a test of explanation of cause of so-called foam collapsing in the chosen productive enterprise were presented. Six Sigma method was used to the problem solution. Design/methodology/approach: In this paper a detailed plan for implementation of Six Sigma quality management conception in order to eliminate the collapsing effect of polyethylene foam during its cutting was showed. The detailing analysis of the polyethylene foam aging cycle (degassing) was carried out. Next the appropriate measures and procedures to eliminate collapsing foam effect were implementation. Findings: Six Sigma leads to an effective improvement of the financial results of the enterprise by controlling and planning of a course of work to minimize waste formation and raw materials consumption. These actions make possible a greater customer satisfaction. Research limitations/implications: In these investigations was established that a decisive influence on the quality of polyethylene foam had the first five days of the seasoning. The proper weather conditions assure obtainment of the product meeting the basic qualitative standards. It was also found that the polyethylene foam rolls which were cut directly after production they were less subject to the process of shrinkage than the rolls cut after several days since the moment of production. Practical implications: Six Sigma is a well-chosen collection of tools which orientate to the approach to improvement and problems solution in the processes. This results the workings which characterize conscientiousness in the everyday work, maturity in the decision making, responsibility in the tasks realization, consequence in applying suitable tools and effective co-operation in the group. Six Sigma method can be used not only in the production but also in logistics, administration or in services. Originality/value: In the article the result of the project realization is the introduction of the proper actions and procedures which should bring the improvement of the quality of finished products and financial results of the enterprise.
