Open loop process control
Webnote: For those new to the industry, open loop process control uses a set pressure to force polymer into the mold during first stage injection – adversely, closed loop control uses a velocity setpoint to control the filling of the mold. Obviously, if your molding machine is limited to open-loop control, the you can perform the test, but make ...
