One great way to get your employees excited about energy reduction is to provide a method of monitoring energy consumption. If your employees can actually see that a change, such as increasing 1st stage injection speed or reducing 2nd stage packing time, actually reduces the power consumption it can become a very empowering experience. There are many options available for this, but one which allows you to track consumption for individual machines over time would be most helpful.
You may still have to make a few more adjustments to the cooling time and coolant temperature to get the optimal settings, but this will get you close in a very short period of time.
The following is a formula which can be used to quickly determine the screw speed during setup. This is based on consuming 80% of the cooling time for shot recovery.
The documentation of coolant temperature both entering and leaving the mold is critical to good documentation. This reduces the time required to get to first piece approval during mold start-ups. Troubleshooting will also become much easier, faster, and efficient.
