Injection Molding: How Repeatable is Repeatability?
Process repeatability is not a constant, but varies over time in response to a number of variables. That variation is not captured by a snapshot in time—measuring a discrete sample of parts. And the only way to manage that variation is with process controls that adjust each and every cycle.
