This methodology solves a very practical problem most molders encounter: Each time the mold is put in a different machine, while a good setup technician will use similar conditions he is usually starting as though the mold is brand new. This slows down the time from the initial shots to getting an adequate production cycle. Scientific Molding looks at the molding process from the point of view of the plastic not the machine settings optimizing each portion of the molding cycle. With this approach once a mold has been qualified, a very simple spreadsheet program can translate the machine settings from one machine to the next to its optimum to get the highest quality part and the fastest practical cycle in a disciplined step by step (scientific) manner
