Hot runner injection mould can realize automatic production.

Hot runner system mould is need to be managed reasonably.

In the production,plastic factory need change products color to meet thr market requirement.

Different plastic and colored plastic changing is a difficult technology.

In this article,we mainly introduce open gate nozzle color changing process.

Open gat nozzle color changing process has 6 steps in total.

Hot runner system change color step:

Worker use new colored plastic to clean the injection machine charging barrel.

All temperature of the hot runner system heating zone increase 10~20℃,but lower the plastic processing temperature

Inject 10~15 times to closed mould until the old colored plastic just show beside the gate around.

Turn off the hot runner system heating and break off mould cooling of temperature system.

Heating the hot runner system handling temperature.

High speed inject until get the even colored plastic.

Open gate nozzle color changing process is more easy than the shut off hot runner system.

And hot runner system don’t allow the different kinds plastic changing.

This is because hot runner system and mould is design according to plastic flow speed and shrinking percentage.

Anole hot runner is one of the innovation and best hot runner system manufacturer in China.
