Machine Controls Summary

This section identified the control units for microprocessor controlled and older relay-logic controlled injection molding machines, their location, and their function. These include the control panel and computer. This information helps to describe the injection molding cycle and what components are involved to produce injection molded parts. On microprocessor controlled machines, a computer is used to make adjustments to the process whereas on older relay-logic machines, manual limit switches, valves and timers are used to make adjustments.
