Development of Energy-Saving Electronic Component Manufacturing Equipment
At Murata, we are developing electronic component manufacturing equipment that has a high rate of energy efficiency. Our indicator for the energy savings realized by this manufacturing equipment is energy consumption per unit of production (per unit of net production). We are developing the new equipment with the goal of a 50% or higher reduction in energy consumption against benchmark machinery (conventional manufacturing equipment).
We have also been proceeding with energy-saving improvements to the existing manufacturing equipment in operation at our plants, focusing on measures that will realize the greatest reductions in CO2
emissions. In fiscal 2017, we focused on a horizontal rollout of approximately 70 energy-saving measures for manufacturing equipment that we have formulated to date.
Our main energy-saving initiatives included: 1) The installation of heat exchangers to enable us to use the waste heat from drying equipment; 2) The operation of heat treatment equipment in eco mode; 3) The use of vacuum plants for ejectors; and 4) Ensuring that air blowers are turned off when equipment is standing by.
In addition, every year we conduct energy-saving training workshops for production equipment design engineers in their second year of employment, providing them with know-how in relation to the design of production equipment in order to realize energy savings.
In fiscal 2018, we will continue to standardize energy-saving improvement measures that have proven successful, and incorporate them into the standard functions of production facilities. By this means, we will accelerate the introduction of energy-saving production equipment and promote the further horizontal rollout of energy-saving measures.
