1) Meter Controlling System:

a,The temperature controller for the main extruder is OMRON temperature controller from Japan. Solid relay is used for heating and cooling loop. The solenoid valve is imported from Netherland

b,The current displayer is Chang Shuan brand from Taiwan

2) Main Extruder Interlock Protection Function:

a,Main Extruder interlocks with the lubricant pump for the gear box and the fan for the main motor

b,Main extruder interlocks with the feeder, when the extruder stops, the feeder will stop immediately；

c,The main motor has protective functions of over current, under voltage, lack of phases, over heat and block running.

D,There is melt pressure and melt temperature display function on the die, of which the melt pressure interlock with the main extruder to realize the over pressure protection on the die

3) Main breaking switch is joint venture products

4) Small AC contactor is Schneider products

5) New type motor protective air switch is joint venture product；

6) Controlling button and indicating light are Schneider products
