Time, RAMP TIMES and Velocities. Unofortunately This Complicates inject Molding Processing, and in my opinion class options are highly derimenental for consistentent porta.
Machine Manufactuers are eager to come up with more sophisticated processing mode.
Possible Variations Within Second Stage Between Different Machines:
Pressure for 8 sec. SEE FIGURE 1.

(Pressure Limited) and the Machine Holds A Constant 10,000 PSI for Whatever Time Remains of the 3 SEC.
Pressure in Red, Cavity Pressure in Green; (Scales Not Identical). As can be seen my Attempts to gain Process consisteency, after market, we not successful.
And FASTER Computers Available, Programmers with Good Intents are adjing features & mdash; Packing Velocity as an exmple & mdash; that hinder propuctsisister.
With second-stage (Pack or Hold) Velocity Control, It is Best to Have Cavity-Pressure Sensing.
