End of previous process

• Remove preceding resin from the hopper and discharge inside the cylinder.

Preparation

[ Detach the nozzle from the mold ]

It is not necessary to change the molding temperature of preceding resin if the right temperature range for Z CLEAN is kept.

If dry color is used, clean the hopper thoroughly.

Clean inside the cylinder

[ Z CLEAN charge ]

The normal consumption ranges from 3 to 5 shots (varies according to the color state)

[ Injection purge by Z CLEAN ]

A higher injection speed enhances the cleaning effect. In case of an open nozzle, a backpressure purge (*) also enhances its the effect.

※Backpressure purge is a way of successive extrusion of Z CLEAN by measurement of backward pressure.

Clean inside the hot-runner mold

[ Attach the nozzle to the mold ]

It is not necessary to change the temperature of mold if the right temperature range for Z CLEAN is kept.

[ Clean inside the hot-runner mold with Z CLEAN ]

Return the gauge of molding machine properly.It allows to shorten cleaning time with short cycle (curtail cooling time)

Replace remains inside the cylinder with succeeding resin

[ Succeeding resin charge ]

Set the suitable temperature for succeeding resin.

An increase in the nozzle temperature by 20 to 30°C allows faster replacement with succeeding resin.

【Injection purge by succeeding resin】

Replace Z CLEAN with succeeding resin.

Replace remains inside the hot-runner with succeeding resin

[ Attach the nozzle to the mold ]

[ Replace remains inside the hot-runner mold with succeeding resin ]

Replace Z CLEAN with succeeding resin.

Check of the molded form
