Flow Lines. Description: Flow lines are streaks, patterns, or lines - commonly off-toned in color - that show up on the prototype part as a consequence of the physical path and cooling profile of the molten plastic as it flows into the injection mold tooling cavity. Injection molded plastic begins its journey through the part tooling via an entry section called a “gate.”

Part Two of a Two-Part Series Valve Gate Sequencing ...

Valve gate 1 closes when the pressure has fallen to 3,300 psi. Material at gate 2 reaches the maximum pressure and begins declining and gate 2 closes when the pressure falls to 2,700 psi. In this scenario, the discharge is used to minimize compressive stress in the valve gate areas and to minimize warp while eliminating knit lines in the part.
