Said to reduce shot hesitation, blush, and air entrapment and to ensure overall smoother, more consistent filling.

EvenFlow is a new variable-pin-speed valve-gate hot-runner controller from Plastic Engineering & Technical Services ( P.E.T.S.), Inc., Auburn Hills, Mich. Starting the valve opening at low pin speed is said to reduce shot hesitation, blush, and air entrapment and to ensure overall smoother, more consistent filling. EvenFlow allows touchscreen control of pin speed from 20% to 100% of full speed. The controller works with a variety of valve-gate systems.
