EPS Expandable Polystyrene Foam Beads Pre Expander Machine Production Line

Automatic PID adjusting and control system, temperature sensor automatic feedback. PID steam and compressed air automatic adjusting to achieve different steam temperature for different density requirement. Temperature tolerance is ±0.2℃, temperature remain stable. It achieves constant temperature and constant pressure foaming, ensure the foamed beads density evenly, foaming accuracy ±1%.
Weighing feedback system adopts famous brandsdedicated weighing controllers, controlled by PLC and touch screen. The weighing system can accurately weigh the foamed beads weight, give feedback in time. By adjusting feeding material weight to control the foam density accuracy.

01Vibration level sensor control system

It adopts Germany imported vibration level sensor to control the foaming beads level to achieve accurate volume control, then ensure foaming density accuracy.

01Vacuum drying system

Vacuum drying system adopts vacuumize drying method, drying forming time short, ensure foaming more uniform & accurate and ensure clean discharging, when weighing samples will not confuse and feedback is accurate.
