CAVITY AND CORE COMPONENTS Mold Vac MOLD VAC - Vacuum & Blowback Controller Custom microprocessor allows for precise control of vacuum and blowback. Control - Custom microprocessor allows for precise control of vacuum and blowback functions. Vacuum control can be adjusted to 1/10th of a second, eliminating flash and improving part quality. Limit Switches - One set of limit switches are provided. 1st (mounted on platen) is energized at mold closed (vacuum). The second switch is energized at mold full open (blowback). Vacuum Circuit - Eliminates part burns, voids, and short shots. Reduces reject rates and improves part quality. Vacuum cycle can be adjusted from 0-24”hg. Vacuum Reservoir - All units are designed with a vacuum reservoir which is discharged at mold closed. This feature provides an instant vacuum within the mold. Blowback Circuit - The patented two-phase blowback assists in part ejection (1st phase) and purges vented pins (2nd phase) after each cycle. Purging of the vent pins reduces mold maintenance and increases productivity.
