The Equinox system built into Sidel’s rotary blow molding machines is designed to ensure consistent, top quality PET bottle production for better overall bottling line efficiency.

Equinox monitors and corrects bottle quality during production regardless of output rate. No samples are required because Equinox automatically measures the exact weight of every bottle base. If the system detects variations from the setpoint weight, it corrects the problem by adjusting certain blow molding parameters. No machine shutdown is required.

Equinox automatically measures the exact weight of bottle bases using sensor modules that emit infrared light. If the weight is beyond the tolerance limit based on the initial setpoint, the blow molding machine’s control algorithm is automatically triggered, and the operator receives a warning about the problem. Changes to pre-blow pressure regulate overall production on all stations, and modifying the start of pre-blow adjusts individual stations.
