Machine Adjustments & Settings

Fixing mould tools

The aluminium mould cooling bolster has internal water channels and care must be taken to ensure holes

avoid the water channels shown. All dimensions in mm. The internal water channels are 10mm diameter.

Pyrometer Air Pressure

The pyrometer has air cooling to prevent over-heat, it is important that this air supply is always connected. A

pressure tank is provided to give the pyrometer air system a short term reserve supply if the main air supply

is disconnected. If the reserve air supply pressure falls then the heaters will turn off and the symbol will

show on the control screen. The pyrometer air supply may be adjusted using the regulator situated on top

of the reserve tank.
