Selection of Force Creation Method for Press Forming Machinery

Environmental aspects have become increasingly important in today's business. In packaging industry this has created an increased demand for fibre-based packaging solutions which present a renewable and environmentally friendly alternative for oil based materials. One of such materials is paperboard, and for example trays made of paperboard can be an alternative for traditionally used plastic trays in food packaging. Nowadays there is a need for cost-effective small scale machinery. In this study the objective was to define the best method to produce the force needed in the compact paperboard tray pressing machine. Two different force creation methods were studied in this article using Score Table -analysis and SWOT-analysis.Results indicate that the electric actuator system had several key features compared to the hydraulic system that gave it a clear advantage, including high force production, accuracy and cost efficiency.
