The main objective of the project is to identify, study, and understand potential improvements of the Sealing Applicators production line of Ecco Finishing/Carlisle Fluid Technologies Company. The ergonomic cases in the plant, established as working postures, will be analysed using manual methods and virtual simulation tools. The analyses will be based on the measurements and depth of the data that is compiled during the visits to the plant. The software used to perform the ergonomic simulations, Siemens Jack 9.0, also has its limitations for each working posture of the production line, as some data for building the postures is missing due to limitations of the measurement taking process. The final result of the project is set of data that includes a solution implementation of the working postures analysed, also developed with simulations in Siemens Jack 9.0, of the production line, that could improve daily working life of the workers in the plant as well as management of the company. The project results reveal a need to add as well as alter elements of the workstation to make sure that the posture the user performs when working adheres to ergonomic principles.
