Shut-Down

To shut down the process:

1) Shut the feed throat to prevent any more plastics pellets from entering the screw and barrel assembly. After the machine cycles a few times, put it in semi-automatic mode.

2) After the completion of the one cycle, place the machine in the manual mode. Move the injection carriage away from the mould.

3) With the purge guard down, reduce the injection velocity and slowly jog the screw forward, repeating this procedure until all of the material has been purged. Leave the screw in the forward position.

4) Coat the mould with a mist of mould saver and close it, but do not put it under clamp tonnage.

5) Shut down the hydraulic pump and barrel heaters.

6) Be sure to shut down the mould heater or chiller and de-pressurise the water lines.






· Most mould heaters and chillers have a vent button that will de-pressurise the water lines and displace water to either the drain or back to the chiller return line.
