Process conditions require a relatively high use of energy for the production of moulded rubber products. The largest percentage used is electrical energy followed by cooling water and compressed air. The ever-increasing cost factor for energy has become a real concern in the production of rubber parts. The requirement for energy is increasing steadily, and in turn the effect on the climate is becoming more apparent worldwide. This lecture will survey the fundamental possibilities for energy saving during the production of moulded rubber products. We will especially look at the energy required to drive the motor and pump along with the pneumatic consumption as well as heat losses from the heating required for production. Process optimisation systems like Cure also make an essential contribution to the energy savings. Machine cycles can vary and production processes can be different so the application of single measures for energy saving has to effect the overall saving.
