RESUMO

Many times, for some products classes, inputs as packaging may have an expressive weight in the final product cost structure. In the case of products packaged into plastic containers, this is an usual scenario that has as result, the increase of performance requirements of the blow mold machines that produce such containers. A point to be studied in the blow mold machines to fulfill such requirement is an analysis of its hydraulic system in a way to reduce the positioning time in the most significant movements performed by its main devices. Such devices have electro-hydraulic position and speed controls composed by flow control and proportional valves and linear actuators. So, it is presented in this work the description of blow mold machine, modeling of hydraulic components involved with the main equipments movements and an experience to record physical values as pressures and positioning speeds using an existent blow mold machine as testing bench. The tested registers can be confronted against the results obtained in the modeling analysis as a target to make the blow mold machine more productive besides of validate the model to the future projects.
