Products Detail

Auto Batch Pre-expander Machine

Control System

PLC and human-touch Control, automatic operation, convenient maintenance.
Easy and fast working process switching with computer memory function.

Structure Design 

Weighing system is placed on top of the barrel
High-quality closed hot air drying system
Spare parts and fittings are from well-known brands which keep the machine in a long service life

Processes

Electronic weighing system, photoelectric level control system, and automatic negative pressure filling device, keep the weight of expandable material accurately and the error rate of density ≤3%.
The temperature and steam pressure in the barrel are controlled by advanced Japanese high-precision pilot pressure reducing valve, ensure the pressure at the outlet of the reducing valve is always constant. The temperature in the barrel Temperature fluctuation control within ± 1% ℃
Closed constant pressure foaming is suitable for foaming production in high altitude anoxic areas
The automatic discharge of the barrel adopts compressed air blowing
Once forming and circular production.

Production Efficiency 

High efficiency and low labor intensity

Energy savinglow cost.
