This training, the second in a twopart series, ensures math skills needed for the injection molding worker. Mathematics is used throughout the injection molding industry on a daily basis in many different capacities. It can be as simple as counting inventory or as complex as calculating the tonnage required for a multicavity mold.
Math skills are required to perform common tasks like calculating part tolerances, determining production requirements, or comparing measurements. They are critical when performing advanced functions, such as; intensification ratio calculations and converting hydraulic pressure to plastic pressure  all of which are covered within this two part training program.
