The injection molding plant and the profile extrusion plant have broadly similar base loads (both in magnitude and in percentage terms) but the extrusion site has a process load only 30% of that of the injection molding site (0.
As we discussed in last month's column, your plant's "energy fingerprint" is composed of the base load and the process load.
For a typical plant, the base load should lie in the range of 10% to 40% of the average total load.
This is average for plastics processing, where typical base loads are between 10% and 40% of total energy use.
Energy usage at a plastics processing plant consists of a base load and a process load.
The energy cost for this site consists of a base load of 152,440 kwh and a process load of 1.
One of the main reasons for this is the base load of these machines.
Check the base load for older hydraulic machines by monitoring the energy used with the main motor running but with the platens not moving--and be prepared for a big surprise.
