Purge Compounds for plastics processing machines

Recommendable Cleaning Process

1.Plastics purge with Injection Molding Machines

Please follow the procedure below.
Finish molding.
↓
Purge the remaining plastics.
↓
Set the back pressure zero,
throw CELPURGE in.
Repeat mete and purge to clean the inside of cylinder.
↓
Put the subsequent material into the hopper.
Repeat metering and purging to change over.
↓
Start injection molding.

2.Recommendable machine settings

For cleaning the cylinder of injection machines, consecutively perform the “1st cleaning/Basic cleaning” and “2nd cleaning/Nozzle cleaning” shown below. The purging times or other conditions in the table are rough standard. Please adjust them to the plastics you use or the dirt of your machines.

	Number of mete & purge	Machine settings
		Metering position	Barrel temp	Screw rotation	Injection pressure	Injection speed	Back pressure
1^st. cleaning: Basic cleaning	5 ~ 10	Same as preceding setting	Same as preceding setting	70% of MAX (*)	70% of MAX.	70% of MAX.	0
2^nd. cleaning: Cleaning nozzle	> 15	Approx. 30mm

(*) Be sure the torque of screw is not too high.

When it seems that the whole barrel cleaning is necessary, set the metering position maximum.
