This master’s thesis evaluates the quality stability of the production process for film-faced panels by analysing various technological parameters. The research is relevant to the production of ready-to-assemble furniture, where MDF and MDP panels are coated with decorative film, and the quality of the final product depends on stable adhesion between the panel, adhesive, and film. The main problem analysed is the delamination of black decorative film from the board, which occurs not only immediately after the lamination process but also during subsequent production processes, storage, and at the customer’s site. The theoretical part of the study analysed the principles of film lamination, the properties of MDF and MDP panels, the influence of environmental conditions, and the main mechanisms of adhesion formation. It was determined that lamination quality depends on surface wetting, physical interactions, mechanical adhesive bonding, and the compatibility of technological parameters; therefore, it can be concluded that the lamination process functions as a multifactorial system in which quality depends on environmental and technological parameters. The practical section examined the main parameters affecting the process: adhesive quantity, uniformity of adhesive distribution, adhesive and calander temperature, line speed, pressure conditions, film type, and the adhesive system used. The research methodology includes the analysis of production data, the calculation of quality indicators, the comparison of technological parameters, and the laboratory evaluation of adhesive stability. Film adhesion is evaluated using methods that closely reflect real-world conditions, including the ISO 2409:2020 cross-cut adhesion test and thermal aging conditions in accordance with the principles of ISO 9142. The study also examines how defect reduction can impact production efficiency, material consumption, and the environmental assessment of the process. The study underscores the importance of integrated process control, where quality stability is ensured not only by regulating individual parameters but by managing their interactions throughout the entire lamination process. |
