Agr International, Inc., Butler, Pa., enhanced its Process Pilot automated blowmolder control system to include Individual Mold Control, which controls the blow parameters for each individual mold station, making it possible to minimize mold-to-mold variation in thickness distribution.
With the Process Pilot system, high-precision thickness distribution measurements are captured on every bottle. Typically the Process Pilot system manages material distribution to a base-line thickness established on an overall average of all mold stations by controlling the oven parameters and P1 pressure as well as start time. These parameters move the material distribution close to baseline to produce a consistent quality of bottles.
