Managing the operation People


Energy efficiency is not all about hardware; the way a moulding plant is operated plays a key role, too. Management and operational improvements can be made at low cost but, as they require changing the way people work, can be difficult to implement and sustain.


Empower your people Training staff and empowering them to switch off machines, processes and services can lead to energy reductions of up to 20%.


Make a good start Use check sheets to ensure machine start-ups are correctly sequenced to bring the biggest energy users, such as main motors, on line at the latest possible time. This applies to services, too; don’t turn on chilled water until the mould requires cooling.


Manage processes Process setting has a major impact on energy use as well as quality and productivity. So apply ‘scientific moulding’ principles; determine optimum settings then ensure they are recorded and applied. And make sure machine settings are not changed without management approval.


Minimise consumption Machines should be placed in stand-by mode during temporary production interruptions (main motors and downstream equipment switched off and heaters set back). Shut-down completely during extended stoppages.


Improve maintenance All production plant must be well maintained and controls fully functioning to achieve efficient production. Machine monitoring can provide early warning of essential maintenance; a preventative maintenance programme is even better.
