Vac-Alert’s patent-pending technology provides real-time vacuum level inside the die cavity, through measurements taken by Midland’s ‘iBlock’. iBlock alerts users when the vacuum level falls below a programmed level in Inches of Mercury (“Hg), Kilopascals (kPa), Torr or PSI. When the pre-determined level is reached, the user can select to have the machine shut down to prevent more unacceptable parts from being made. Vacuum sensors, installed at critical locations in the vacuum system, also detect performance degradation and notify the user of those issues, via the VMS-100 touch screen interface. Data capture begins just before the solenoid valve opens, through the end of fast shot.
